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.


Polymer cage 

The cage is a key component in achieving  reliability and safety of tapered roller  bearing units. Cages in rolling bearings  perform several tasks: 

• During operation, the rolling elements  pass from the loaded into the unloaded  zone where the cage has to guide the  rolling elements.

• Provide and distribute lubricant and  dampen vibrations. 

• Provide correct retention of the rolling  elements during mounting and  maintenance operations, thus enabling  easier handling.  Historically, pressed steel cages were applied  for TBUs. Today, mainly polymer cages are  used. They have been in operation since  1990 with excellent results. Pressed steel  cages are fitted only on specific customer  requests [18, 19].

Universal polymer cage 

The new Universal Polymer Cage (UPC)  design widely replaces the conventional  steel cages within a tapered roller bearing  unit. This cage design meets the  requirements of typical AAR inch size TBUs  and is used to upgrade existing bearings  during remanufacturing.  This cage also helps to extend the service  life, performance and reliability of the  bearing. Positive field-test results in North  American rail services led to an  unconditional approval from the AAR for  SKF to retrofit and upgrade existing class F bearing units, manufactured by all major  bearing suppliers to the North American  market, with the SKF UPC cage

Tapered roller bearings belong to separable bearings. The outer ring and inner ring which is composed of

roller and cage component can be installed separately. The inner and outer rings each having a tapered

raceway. According to the number of columns roller they are divided into single row, double row and four row

tapered roller bearings, such as different structural types. Tapered roller bearings are up to the amount of

single row tapered roller bearings. Single row tapered roller bearings can support radial load and axial load in

one direction. When the bearings bear radial load, they will produce an axial component, so you need another

which can withstand axial force in the opposite direction in order to be balanced.
