W 6203-2RS1/VP311 Bearing Product Overview & Core Advantages
The W 6203-2RS1/VP311 is a single row deep groove ball bearing designed for high reliability and durability in demanding applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. A key feature is its sealed design with contact seals on both sides (2RS1), which effectively retain lubricant and exclude contaminants, enabling long-term, maintenance-free operation. Pre-lubricated with a specialized grease (VP311), it is ready for immediate use and performs reliably across a wide temperature range from -30°C to 120°C. This bearing is engineered to support primarily radial loads and is characterized by its low friction and smooth running operation.
Model Code Breakdown
- W: Indicates a bearing with a stainless steel construction.
- 6203: The basic bearing designation, specifying the bearing dimensions (17 mm bore, 40 mm OD, 12 mm width).
- 2RS1: Signifies that the bearing is fitted with contact seals on both sides. The "RS1" type seals are made of NBR rubber and provide effective protection against contamination.
- VP311: Denotes that the bearing is pre-lubricated with a specific grease. This grease is suitable for the specified temperature range and contributes to the bearing's long service life.
W 6203-2RS1/VP311 Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and cage, are made of stainless steel, providing superior corrosion resistance and making it ideal for applications exposed to moisture or aggressive environments.
- Effective Sealing: The double-sided contact seals (2RS1) reliably shield the bearing interior from dust, dirt, and moisture, while retaining the lubricant. This design significantly enhances operational reliability and service life, especially in unclean conditions.
- Optimized Lubrication: The factory-applied VP311 grease ensures immediate and smooth operation from the first start. It is formulated to perform consistently within the specified temperature range, reducing wear and maintenance needs.
- Precision and Load Capacity: Manufactured to P0 tolerance class and standard radial internal clearance (CN), this bearing offers reliable performance for a wide range of applications. It is rated for a dynamic load of 1812 lbf and a static load of 1068 lbf.
