Spherical roller bearing 22217 EKJW33 NSK 85x150x36

Self-aligning bearing for heavy-duty industrial applications

High durability, load capacity and misalignment compensation

B2B solution for machinery and bearing housings

Main description

The 22217 EKJW33 spherical roller bearing from NSK is a high-performance rolling bearing designed for demanding industrial applications where reliability, high load capacity, and long service life are critical. With dimensions 85x150x36, this bearing is widely used in heavy machinery, drive systems, and equipment operating under high mechanical stress.

The spherical roller bearing design provides self-aligning capability, allowing the bearing to compensate for shaft misalignment relative to the bearing housing. This feature significantly reduces stress on the bearing and surrounding components, making it a superior choice compared to standard solutions such as a ball bearing, which require precise alignment. As a result, the 22217 EKJW33 NSK bearing ensures stable operation even in challenging installation conditions.

The EK designation indicates a reinforced internal design with a tapered bore, enabling mounting on an adapter sleeve. This simplifies installation and removal, which is especially important in maintenance-intensive industrial environments. The W33 feature includes lubrication grooves and holes in the outer ring, allowing efficient relubrication during operation and contributing to high durability and extended service intervals.

This spherical roller bearing is capable of carrying very high radial loads along with significant axial loads in both directions. It is commonly used as part of a complete bearing unit in heavy-duty machinery, conveyors, crushers, industrial gearboxes, and production equipment. The consistent quality and precision manufacturing of NSK make this bearing a trusted solution for OEM manufacturers and maintenance teams seeking reliable long-term performance.
