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 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  of the first order. It is very important for the correct fitting and functioning of the bearing that the same assembly number is quoted for  all subsequent replacement orders for that specific bearing position. Standard and supplemental assembly numbers are listed in  this catalog starting on page 55.  Timken should be consulted if additional information is needed on  any combination of parts or if questions arise about the correct  assembly number for a specific application.
