Product description of TIMKEN Bearing 239/850KYMBW906AC3

TIMKEN Bearing 239/850KYMBW906AC3, It belongs to TIMKEN Bearing > Spherical Roller Bearings > Spherical Roller Bearings - Brass Cage. 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 239/850KYMBW906AC3,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.

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. • Run at consistently lower temperatures than same-size competitive bearings for greater reliability • Multiple cage designs – including a wide range of both steel and brass options – help reduce stress at high shock loads or speeds and provide strong contaminant purge • Optimized internal geometries deliver the highest load and speed ratings in the industry he principle styles of radial spherical roller bearings that Timken offers are: • ≤600 mm outer diameter: EJ, EM and EMB • >600 mm outer diameter: YMB, YMD and YP Above suffixes correspond to different types of designs depending on a bearing size and geometry. Main differences are the cage type used in the assembly. Spherical roller bearings with an EJ cage suffix are fitted with a hardened stamped-steel cage. YM/EM/YMB and YMD suffixes are used with brass cage designs. YP is a pin-type cage specific for large diameter bearings.

TIMKEN Bearing 239/850KYMBW906AC3, The high performance Timken® EJ, EM and EMB bearings offer higher load ratings, increased thermal speed ratings and reduced operating temperatures compared to the previous offering.

In addition to these improvements, cage designs vary between the different styles as noted below. See the cage section for more details. Style Cage Design EJ Land-riding steel cage; one per row EM/YM Roller-riding one-piece brass cage EMB/YMB Land-riding one-piece brass cage YMD Land-riding two-piece brass cage YP Steel pin-type cage.

EM, EMB, YM, YMB and YMD bearing cages are precision machined from brass as shown in figs. 4-7. Their rugged construction provides an advantage in more severe applications. The open-end, finger-type design permits lubricant to reach all surfaces easily, ensuring ample lubrication and a cooler running bearing. EM, EMB, YM and YMB are all one-piece designs that are differentiated by their means of guidance within the bearing. With EM and YM designs, the cage mass is low and the rollers are used for guidance, while EMB and YMB cage designs typically have more mass and guide on the inner ring. YMD cages are similar to YMB, except they have a two-piece design. Two independent cages, one for each row of rollers, are assembled into an individual bearing. This allows each row of rollers to rotate independently when required by the application, and minimizes bending of the cage fingers.
