D/W R1-4 R-2ZS Bearing Product Overview & Core Advantages
The D/W R1-4 R-2ZS is a miniature single row deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while its shielded (2ZS) construction retains lubricant and protects against contamination, ensuring long service life and maintenance-free operation in demanding environments.

D/W R1-4 R-2ZS Bearing Structural Features & Performance Benefits
- Compact & Robust Design: The single row deep groove raceway and flanged outer ring facilitate easy mounting and axial location, providing a compact and rigid bearing solution.
- High Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is ideal for applications exposed to moisture or corrosive media.
- Maintenance-Free Operation: The 2ZS contact seals effectively shield the internal components from contaminants and retain the pre-applied grease lubrication, enabling long-term, maintenance-free performance.
- Precision Performance: Built to P0 tolerance class and standard CN radial internal clearance, it ensures smooth and quiet operation, suitable for high-speed applications up to 85,000 rpm.
