W 6003-2RS1/VP311 Bearing Product Overview & Core Advantages
The W 6003-2RS1/VP311 is a single row deep groove ball bearing designed for high reliability and precision in demanding applications. Its sealed construction and stainless steel components provide excellent corrosion resistance and long service life. This bearing is engineered to accommodate primarily radial loads and offers a compact design, making it ideal for applications requiring a robust and space-saving solution with consistent performance.
Model Code Breakdown
- W: Designates a bearing with a stainless steel construction.
- 6003: Standard designation for a deep groove ball bearing with a 17mm bore, 35mm outside diameter, and 10mm width.
- 2RS1: Indicates the bearing is fitted with two contact seals (one on each side), providing effective protection against contaminants and retaining lubricant.
- VP311: Specifies the grease filling and type, optimized for the bearing's operational temperature range and speed capabilities.
W 6003-2RS1/VP311 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its specific design features. The single row deep groove raceway is precision-ground to facilitate smooth operation and handle radial dynamic loads up to 1111 lbf. The use of stainless steel for the rings, balls, and cage ensures superior corrosion resistance, making it suitable for harsh environments. The 2RS1 contact seals effectively shield the internal components from dust and moisture, while the pre-applied grease lubrication (VP311) ensures immediate operation and contributes to its maintenance-free characteristic over a wide temperature range of -30°C to 120°C. With a limiting speed of 13,000 rpm, it is well-suited for high-speed applications.
W 6003-2RS1/VP311 Bearing Typical Application Areas
The W 6003-2RS1/VP311 is commonly specified in various industries and equipment, including:
- Food processing and packaging machinery
- Medical and dental equipment
- Chemical processing pumps and mixers
- Electric motors and small gearboxes
