Timken 22213EJW33 Spherical Roller Bearing

Description

The Timken 22213EJW33 is a high-performance spherical roller bearing designed to handle demanding industrial applications. It features two rows of symmetrical rollers, which can freely align themselves in the spherical outer ring raceway. This design allows the bearing to accommodate shaft deflection and misalignment between the shaft and housing. It is ideal for applications with heavy radial and moderate axial loads.

FAQ

What does the suffix 'EJW33' signify?

The 'E' indicates an optimized internal design for increased carrying capacity. The 'J' denotes a stamped steel cage, which is standard for many spherical roller bearings. 'W33' signifies that the bearing has an annular groove and three lubrication holes in the outer ring to facilitate efficient lubrication.

While spherical roller bearings are primarily designed for high loads and accommodating misalignment, the 22213EJW33 with its steel cage can operate at moderate speeds. For very high-speed applications, alternative cage materials (like brass or polymer) and specific lubrication methods should be considered. Always consult the manufacturer's datasheet for precise speed limits.

The W33 feature is designed for relubrication through the housing. Grease should be supplied through the lubrication holes in the outer ring, allowing it to distribute evenly across the rolling elements. It is crucial to use a compatible grease and follow the machinery's recommended lubrication intervals to ensure optimal bearing life.
