D/W R2-2RS1 Bearing Product Overview & Core Advantages
The D/W R2-2RS1 is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This inch series bearing features a sealed construction, making it ideal for applications demanding high reliability and minimal maintenance. Its primary strength lies in efficiently handling radial loads while offering robust operation. Manufactured entirely from stainless steel, it provides excellent corrosion resistance, ensuring longevity in challenging environments. With its small bearing dimensions (0.125" bore, 0.375" OD) and precision P0 tolerance class, it is a superior choice for high-precision, compact assemblies.

| 2RS1 | The bearing is equipped with two contact seals (RS1 type) on both sides, providing effective protection against contaminants and retaining lubricant. |
D/W R2-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The double-sided contact seals (2RS1) effectively shield the internal components from dust, moisture, and other contaminants, while securely retaining the pre-applied grease. This results in a maintenance-free and long-service-life solution.
- High-Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is inherently resistant to rust and corrosion, making it suitable for applications exposed to harsh or washdown environments.
- Precision and Reliability: Built to P0 tolerance class and standard CN radial internal clearance, it ensures consistent performance, smooth operation, and high running accuracy for general precision applications.
- Optimized Lubrication: The bearing is pre-lubricated with grease, which is suitable for the specified temperature range of -30°C to 120°C, providing immediate readiness for installation and reliable operation.
