Spherical roller bearing 22217 EJW33 NSK 85x150x36

Self-aligning bearing for demanding industrial applications

High durability and resistance to misalignment

Reliable solution for bearing housings and bearing units

Main description

The 22217 EJW33 spherical roller bearing from NSK is a high-performance rolling bearing designed for heavy-duty industrial applications where high load capacity, reliability, and long service life are essential. With dimensions 85x150x36, this bearing is widely used in machinery operating under continuous load and harsh working conditions.

The spherical roller design provides excellent self-aligning capability, allowing the bearing to compensate for shaft misalignment relative to the bearing housing. This feature significantly reduces stress caused by mounting inaccuracies, shaft deflection, or vibration. Compared to a standard ball bearing, the 22217 EJW33 offers superior performance in applications where alignment cannot be perfectly maintained.

The EJ designation indicates a reinforced internal construction with a robust cage, optimized for high radial loads and improved operational stability. The W33 feature includes lubrication grooves and holes in the outer ring, enabling efficient relubrication during operation. This design supports consistent lubrication, contributing directly to high durability and extended bearing service life.

The 22217 EJW33 NSK bearing is capable of carrying very high radial loads as well as substantial axial loads in both directions. It is commonly used as a critical component of a bearing unit in heavy machinery, conveyors, gearboxes, and industrial drive systems. The bearing meets the expectations of B2B customers seeking dependable performance, predictable maintenance intervals, and compatibility with standard industrial bearing housings.
