When Timken introduced its revolutionary AP™ (Ail-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...

TIMKEN® AP BEARING ASSEMBLY • 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 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 The recessed end cap, not shown,...

HOWTO IDENTIFY ASSEMBLY NUMBERS AND PART NUMBERS HOW TO IDENTIFY ASSEMBLY NUMBERS BEARING ASSEMBLY NUMBERS In order 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 maybe alphanumeric, although the first digit For new applications, an assembly number is assigned on receipt of the first order. It is very important...
