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.
