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.
