INTRODUCTION intrODuction When Timken introduced its revolutionary APTM (All-Purpose) railroad 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 bearing 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 attributed to many factors including the bearing’s high load carrying capacity and its adaptability to a wide variety of applications....

Timken® AP Bearing Assembly 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 unavailable through Timken, most bearing distributors provide a selection 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 Vent Narrow Adapter 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...

HOW TO IDENTIFY ASSEMBLY NUMBERS AND PART NUMBERS How to Identify Assembly Numbers and Part Numbers Vent Fitting Bearing Assembly Numbers In order to facilitate the identity of groups of parts, a “bearing assembly 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, performance 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...
