W 634 R-2RS1 Bearing Product Overview & Core Advantages
The W 634 R-2RS1 is a single row deep groove ball bearing designed for exceptional performance in compact applications. This sealed bearing is constructed entirely from stainless steel, providing excellent corrosion resistance. Its primary advantages include the ability to handle radial loads efficiently, reliable operation across a wide temperature range from -30°C to 120°C, and being pre-lubricated for maintenance-free service. The combination of a sealed design and P0 tolerance class makes it a robust and precise choice for applications demanding high reliability and long service life.

W 634 R-2RS1 Bearing Structural Features & Performance Benefits
- Compact & Robust Design: With a bore diameter of just 4 mm and an overall width of 5 mm, this bearing is ideal for space-constrained applications. The flanged outer ring (18 mm outer diameter) facilitates secure and precise housing fit.
- Superior Sealing & Lubrication: The 2RS1 contact seals effectively shield the bearing from dust, moisture, and other contaminants while retaining the factory-applied grease lubrication. This ensures long-term, maintenance-free operation.
- High-Corrosion Resistance: Manufactured from stainless steel for the rings, balls, and cage, the bearing is suitable for use in harsh environments, including those exposed to water or chemicals.
- Reliable Performance: The CN radial internal clearance and P0 tolerance class guarantee consistent and smooth running performance, supporting a limiting speed of 30,000 rpm.
W 634 R-2RS1 Bearing Typical Application Areas
