W 625 R-2RS1 Bearing Product Overview & Core Advantages
The W 625 R-2RS1 is a metric single row deep groove ball bearing designed for compact applications requiring high reliability. Its sealed construction effectively protects against contamination, making it suitable for environments where maintenance access is limited. This bearing excels in handling radial loads and offers smooth operation, contributing to extended service life and consistent performance in precision assemblies.
Model Code Breakdown
- W: Stainless Steel Bearing Series
- 625: Standard Bearing Designation (5mm Bore, 16mm OD, 5mm Width)
- R: Bearing with Flange
- -2RS1: Bearing with two (2) rubber contact seals (RS1) on both sides
W 625 R-2RS1 Bearing Structural Features & Performance Benefits
Compact & Robust Design: The single-row deep groove geometry and stainless steel construction of all components (rings, balls, cage) provide excellent corrosion resistance and durability. The inclusion of a flange allows for easy axial location and secure fitting into housings.
High-Speed Capability: With a limiting speed of 28,000 rpm, this bearing is engineered for high-speed applications. The optimized internal design and effective sealing minimize friction and heat generation.
Maintenance-Free Operation: The double rubber contact seals (2RS1) effectively retain the factory-applied grease and exclude contaminants. This creates a lubricated-for-life system, ideal for applications where re-lubrication is impractical.
