Misalignment. Contamination. High temperatures. Even extreme speeds or critical stresses can present extra challenges when managing high radial loads. Timken® spherical roller bearings can handle it all, with innovations designed to extend bearing life and boost reliability.

Timken® Spherical Roller Bearings with hardened steel cages deliver greater fatigue strength, increased wear-resistance and tougher protection against shock and acceleration. TIMKEN Bearing 23028KEJW33C4,Timken® Spherical Roller Bearings with brass cages provide extra strength and durability in the most unrelenting conditions, including extreme shock and vibration, high acceleration forces and minimal lubrication.

Cages (also referred to as rolling element retainers) serve several purposes in the proper operation of a rolling element bearing. Cages separate the rolling elements and prevent rolling element on rolling element contact and wear. Cages align the rolling elements on the inner ring to prevent rolling element sliding, skidding, and skewing to facilitate true rolling motion. For handling purposes, cages retain the rolling elements on the inner ring assembly to allow for bearing installation. In some instances, cages also improve flow of the lubricant to the bearing inner ring raceways. The following sections discuss the common types of cages used for spherical roller bearings. The basic design geometry, material, and manufacture are discussed for each cage type.

TIMKEN Bearing 23028KEJW33C4,Timken® EJ bearings incorporate a unique stamped-steel cage design as shown in next. The EJ design includes two independent cages, one for each row of rollers, which are assembled into an individual bearing. This feature allows each path of cage and rollers to operate independently, and prevents the cage from bending. This cage is guided on the inner ring and runs above pitch. Each cage is surface hardened (nitrided) to provide improved wear resistance as well as additional strength to allow the bearing to operate in even the most severe environment. Face slots have been designed for improved lubrication flow. This can result in a lower operating temperature and longer bearing life.
