W 6208-2RS1/VP311 Bearing Product Overview & Core Advantages
The W 6208-2RS1/VP311 is a single row deep groove ball bearing engineered for high reliability and performance in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) and pre-filled specialty grease (VP311), making it a maintenance-free solution capable of handling significant radial loads while operating within a wide temperature range. This combination makes it ideal for applications requiring long service life and minimal upkeep.
Model Code Breakdown
- W: Indicates a bearing with a stainless steel construction for rings, balls, and cage.
- 6208: Standard deep groove ball bearing designation with a 40mm bore, 80mm OD, and 18mm width.
- 2RS1: Signifies the bearing is fitted with two rubber contact seals (RS1), one on each side, providing effective protection against contaminants.
- VP311: Denotes the bearing is pre-lubricated with a specific high-performance grease (VP311), suitable for the specified temperature range and contributing to its maintenance-free operation.
W 6208-2RS1/VP311 Bearing Structural Features & Performance Benefits
Robust Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and durability in harsh environments.
Effective Sealing: The 2RS1 rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly extending the bearing's operational life.
Optimized Load Capacity: The deep groove raceway and precision construction enable the bearing to carry high radial dynamic and static loads (5643 lbf / 3957 lbf).
Maintenance-Free Operation: The combination of high-quality seals and pre-filled VP311 grease creates a sealed-for-life unit, eliminating the need for re-lubrication and reducing total cost of ownership.
Standard Tolerances: Manufactured to P0 (Normal) tolerance class and standard CN radial internal clearance, ensuring consistent and reliable performance for a wide range of general industrial applications.
W 6208-2RS1/VP311 Bearing Typical Application Areas
