22217-2RS Sealed Spherical Roller Bearing

Dual Rubber Seals (2RS): Premium integral seals block abrasive grit and moisture while locking in essential lubrication.
Sealed-for-Life Design: Factory pre-lubricated with high-grade, high-temperature EP grease, drastically lowering maintenance costs.
Dynamic Misalignment: Retains full self-aligning capabilities despite the seals, smoothly compensating for shaft deflection.

Deep Application & Technical Narrative:
The 22217-2RS is a highly specialized double-row spherical roller bearing designed specifically to survive in the most heavily contaminated industrial environments. The "2RS" designation means this bearing is equipped with heavy-duty dual synthetic rubber seals and comes pre-packed with premium factory grease. This sealed-for-life design is essential for mining conveyors, bucket elevators, and cement plant machinery where abrasive dust, water, and grit rapidly destroy open bearings. Inside our dedicated assembly workspace, we perform rigorous manual verification on every 22217-2RS unit. We physically check the sealing lip contact pressure and the rotational smoothness to guarantee absolute exclusion of environmental contaminants. This strict attention to detail delivers a zero-maintenance component that drastically reduces downtime and eliminates the need for complex, messy external relubrication systems.
Customized B2B Supply & Packaging Solutions:
We provide a full range of bearing types to meet the strict needs of heavy industrial maintenance networks. The 22217-2RS can be supplied in industrial bulk layouts for OEMs or individual custom-branded boxes for retail. We manage efficient bulk export shipping routes to major industrial hubs in Russia, Africa, and South America.
Targeted Technical Clarifications (FAQ):

Q: Can I relubricate the 22217-2RS?
A: Typically, sealed spherical bearings are designed to be maintenance-free. However, some specific designs may feature a modified W33 groove for slow relubrication, though extreme care must be taken not to blow out the seals with excessive pressure.
Q: Does the 22217-2RS have a different width than a standard open 22217?
A: Yes, sealed spherical roller bearings often have a slightly wider outer ring to accommodate the sealing mechanism while maintaining standard bore and OD dimensions. Always verify housing width compatibility.
