W 630/3 R-2Z Bearing Product Overview & Core Advantages
The W 630/3 R-2Z is a single row deep groove ball bearing designed for exceptional performance in compact applications. Engineered with stainless steel construction throughout (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while its shielded design (2Z) and pre-lubrication ensure long-term, maintenance-free operation. This combination makes it ideal for applications demanding high reliability, smooth operation, and protection from contaminant ingress.

W 630/3 R-2Z Bearing Structural Features & Performance Benefits
- Compact & Robust Design: The single row deep groove geometry and integrated flange provide a space-saving solution with simplified mounting and axial location.
- Corrosion Resistance: Manufactured entirely from stainless steel, this bearing is suitable for applications exposed to moisture, chemicals, or demanding environments, ensuring long service life.
- Shielded & Pre-Lubricated: The 2Z shields effectively protect the bearing interior from dust and other particulates without significantly increasing friction. Combined with factory-applied grease, this creates a sealed-for-life unit, eliminating the need for relubrication.
- Precision Performance: Built to P0 tolerance class with CN radial internal clearance, it delivers consistent and smooth running for a wide range of general-purpose applications.
W 630/3 R-2Z Bearing Typical Application Areas
