revolutionary AP TM All Purpose rail road bearings in 1954 it was a railroad industry milestone Decades later Timken is a leader in the friction management and power transmission industries and continues to lead in advancing bear ing technology through continuous innovation and development In addition to railroad applications AP bearings are successfully used in many types of industrial applications This can be attrib uted to many factors including the bearing s high load carrying ca pacity and its adaptability to a wide variety of applications advantages of Timken AP Bearings Self contained unit provides substantial cost savings in design and installation Many mounting parts are available with the bearing assembly Pregreased unit reduces installation costs Preassembled bearing reduces the number of separate parts to be applied and helps reduce the chance of incorrect assembly High quality tested and improved radial lip seals provide exceptional protection minimum relubrication and low maintenance Positive alignment of rollers is maintained in the bearing due to its basic tapered roller construction This distributes the load over the entire roller length and helps to prevent rollers from skewing On apex design provides true rolling motion with less friction and more resistance to wear Case hardened and hardened cones cups and rollers put hardness where it is needed at the working surfaces The core of these parts being more ductile resists the propagation of fatigue cracks and spalls AP bearings are adaptable to a wide range of applications in new designs and changeovers from other bearing types AP bearings range in bore size from 101 6 to 203 2 mm 4 to 8 inches Optional auxiliary parts can be added to suit a wide range of mounting configurations Bearing Reconditioning Rail Bearing Service Corporation a wholly owned subsidiary of Timken reconditions bearings and related parts used in railroad rolling stock and industrial equipment To learn more about repair for AP bearings contact your Timken representative AP TM BEARINGS FOR INDUSTRIAL APPLICATIONS7 INTRODUCTION A Timken AP Bearing Assembl y Description of Parts The narrow adapter shown in Fig 1 can be used in many ap plications Another type of mounting utilizes a full bore housing see page 21 While this type of housing is currently unavail able through Timken most bearing distributors provide a selec tion from other manufactuerers The bearing assembly is pressed on the axle as a completely sealed unit The axle end cap cap screws and locking plate Fig 1 3D illustration of AP bearing VentNarrow Adapter Cap Screws Backing Ring Locking Plate Basic Bearing Assembly with seals and seal wear ring Axle End Cap can be applied to the axle as a unit When the axle end cap as shown in Fig 1 is used the locking plate provided locks the cap screws The recessed end cap not shown reduces the overall bearing assembly width A piece of soft wire is required to lock the drilled cap screw heads A backing spacer can be used in place of a backing ring AP TM BEARINGS FOR INDUSTRIAL APPLICATIONS8 INTRODUCTION A Class Inner Race Cone Number Outer Race Cup Number d 1 Bore D

to facilitate the identity of groups of parts a bearing as sembly number system is used AP bearings are each assigned a five digit numeric code that follows the cone part number to describe the individual component parts prelubrication perfor mance codes and internal clearance of the pre set assembly In some cases the code may be alphanumeric although the first digit is always 9 For new applications an assembly number is assigned on receipt of the first order It is very important for the correct fitting and func tioning of the bearing that the same assembly number is quoted for all subsequent replacement orders for that specific bearing posi tion Standard and supplemental assembly numbers are listed in this catalog starting on page 55 Timken should be consulted if additional

moisture and kept dry until they are installed on the shaft Bearing assemblies should not be removed from the shipping package nor should the protective wrapping be removed until they are installed Do not remove the cardboard insert from the bore of the bearing assembly This insert will hold the cone spacer in alignment with the bearing cones when installing the bearing assembly on the pi lot sleeve Pressing Bearing Assemblies on Shafts The amount of press fit of the bearing on the shaft is predetermined by the dimensional tolerances of the shaft and bearing cones Tools designed for roller bearing installation and removal should be used Timken AP bearings may be installed or removed with a bearing press wheel press or with portable fixtures depending on produc tion requirements Coat the bearing seats of the axle with castor oil heavy mineral oil or a molybdenumdisulphide and oil mixture Do not use white lead Lead compounds may be detrimental to lubricating greases by acting as an oxidation catalyst A thin coating of rust preventive can be applied to the axle fillet if the standard backing ring Fig 26 is used The rust preventive used must not contain lead or other compounds which may be det rimental to lubricating greases The bearing assemblies are shipped with a protective coating of grease over the vent fitting Care should be taken to see that the grease is not wiped off when the bearings are applied to the axles Fig 26 Separate sleeve method of applying roller bearings to a shaft Roller Bearing Assembly Sealant Backing Ring Hex BoltPilot Sleeve Assembly Sleeve Ram NOTE Heat must not be applied to the bearing cone assemblies to facilitate installation AP TM BEARINGS FOR INDUSTRIAL APPLICATIONS41 TECHNICAL SUPPORT D A pilot sleeve should be used to keep the cone spacer in alignment with the bores of the cones and to guide the bearing assembly on the axle page 45 An assembly sleeve which contacts the seal wear ring outer face and telescopes over the pilot sleeve is used to press the bearing on the axle When the bearing assembly is slipped on the pilot sleeve and the cardboard insert is ejected the seal wear ring should be held in place to prevent it from sliding out of the enclosure seal If the seal wear ring slips out of the assembly it must be inserted into the enclosure seal correctly and carefully chamfered end first so that the outer lip of the seal does not turn under when the seal lips are expanded over the seal wear ring To make sure that the bearings are firmly seated against the axle fillet the forces shown Table 3 should be applied to the bearings after the surge of the pressure gage indicates that the bearings have contacted the axle fillet Due to the rubbing type seals the bearing assembly will not rotate freely at initial application New bearing assemblies are pre set at the factory No adjustment is necessary at installation Applying The Axle End Cap Remove the axle end cap assembly from the carton and remove the cardboard cap screw retainer Apply the axle end cap locking plate and cap screws to the end of the axle as a unit A ratchet wrench or an impact wrench may be used to run up the cap screws Tighten the

Simplified Installation of AP Bearings For Industrial Equipment Installation Methods What does the operator of a machine do when the operator s ma chine located in a remote area away from any sophisticated tools needs a bearing replaced Timken suggests using the following procedures for installing AP bearings when sophisticated tools are not available These methods for installing AP bearings are valuable ways of saving time and money Unlike other tapered roller bearing installations where the individ ual components are installed separately the complete AP bearing assembly should be installed at the same time Hydraulic RAM Method One method of installation utilizes a pressure piston pump and ram in an arrangement as shown at right The 445 kilonewton 50 ton capacity centerhole hydraulic ram is used for the Class D 5 1 2 x 10 bearing Threaded Rod and Nut Method One of the least expensive tooling arrangements for installing our AP bearing utilizes the tools shown in Fig 27 The push tube is counterbored to accommodate our T127 thrust bearing to eliminate much of the friction between the nut face and the push tube Pressure Piston Pump 1 1 4 in Nut Pressure Piston Ram Bearing PilotImpact WrenchFig 27 Auxiliary equipment WARNING Failure to observe the following warnings could create a risk of serious bodily harm Always use suitable personal protective equipment including safety glasses AP TM BEARINGS FOR INDUSTRIAL APPLICATIONS45 TECHNICAL SUPPORT D Tooling Both installation methods used a 1 1 4 in 7 UNC threaded rod SAE 4340 steel hardened 48 53 Rc threaded into a bearing pilot Both methods use a push tube nut and cap screws An example of tooling is shown in Fig 28 Three cap screws are then used to bolt the bearing pilot to the end of the shaft Lubricant is applied to the shaft before pressing on the bearing Required installation clamping force for each size of AP bearing may be obtained from page 42 Comparison of Methods If the user does not own a hydraulic pump and ram the thread ed rod and nut method may be be less expensive However the threaded rod and nut method requires slightly more time and effort to install the bearing Regardless of the method used for installing the bearing assembly it should be made certain that all components are properly seated A distinctive metallic ping occurs at the instant all the components are seated Fig 28 Tooling used to push bearing onto shaft WARNING Failure to observe the following warnings could create a risk of serious bodily harm Proper maintenance and handling practices are critical Always follow installation instructions and maintain proper lubrication AP TM BEARINGS FOR INDUSTRIAL APPLICATIONS46 TECHNICAL SUPPORT D Bearing Removal Axle The bearing assemblies may be removed with a press or with por table fixtures A force of 356 534 kilonewtons 40 to 60 tons is nor mally required to break the bearing fit When it is desirable to remove the bearing without removing a wheel or other adjacent backing part a pulling shoe is used simi lar to that shown in Fig 29 Make sure that the pulling shoe is of the correct size for the bear ing to be removed Proper contact with the backing ring and puller alignment are necessary for efficient bearing removal Position the pulling shoe behind the backing ring The pulling shoe contact surface of the backing ring is very narrow Therefore it is necessary to hold the pulling shoe down in position behind the backing ring as shown below until the initial pressure has been applied to ensure proper contact with the backing ring Extend the ram to remove the bearing from the axle If bearings are to be removed along with wheels make sure that the wheel hub will contact the backing ring or seal wear ring if a backing ring is not used If the axle has large wheel seats a suit able shoe or blocks must be used to make contact between the wheel hub and backing ring When bearings are removed from the axle a pilot sleeve or guide tube should be fastened to the end of the axle or to the press ram to keep the bearing parts together and protect them from damage Do not drop the bearing when removing it from the pilot sleeve After the bearing assembly is removed from the pilot sleeve a tube similar to the cardboard insert or a similar device should be insert ed in the bore of the bearing assembly to hold the internal bearing parts in place Particular attention should be given to keeping the seal wear ring in place in the enclosure seals When bearing assemblies are removed from the axles the bear ings should be disassembled cleaned and inspected Fig 29 Holding the pulling shoe down against the bearing face bearing puller AP TM BEARINGS FOR INDUSTRIAL APPLICATIONS47 TECHNICAL SUPPORT D H o w T o O r d e r

bearing and end cap Lubrication of AP Bearings Timken AP bearings are furnished prelubricated approximately half full with greases approved by the Association of American Railroads AAR Specification M942 78 To help prevent the ingress of contamination it is advantageous for the customer to fill the AP bearing completely full of grease particularly in low and moderate speed applications The grease used to fill the bearing must be compatible with the factory fill grease That is any grease added to the factory grease must not result in grease softening and consequent leakage around the seals A lithium 12 hydroxy stearate soap grease with added rust and oxidation inhibitors is suggested The viscosity of the base oil should be in a range from 150 220 cSt at 40 C 60 100 SUS at 210 F An NLGI No 2 grease is preferred however if there is a problem of pumping an NLGI No 2 grease in cold weather an NLGI No 1 grease can be used In industrial applications factory fill greases are generally satis factory up to 93 C 200 F on a continuous basis and up to 121 C 250 F on an intermittent operation basis For higher temperature operating environments and grease temperatures up to 177 C 350 F a high temperature grease should be used to fill the AP bearing as well as for further relubrication In these instances products utilizing a urea or complex thickener should be used The grease selected must also have rust and oxidation inhibitors and a minimum base oil viscosity of 150 cSt at 40 C 60 SUS at 210 F Frequent relubrication may be required even with higher temperature capability greases
