W 6203-2RS1/W64F Bearing Product Overview & Core Advantages
The W 6203-2RS1/W64F 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 and integrated Solid Oil lubrication, providing a maintenance-free solution that effectively protects against contamination and ensures long service life. This bearing is designed to accommodate primarily radial loads and is characterized by its compact dimensions, low friction, and smooth operation.
Model Code Breakdown
- W: Indicates the bearing rings and balls are made of stainless steel.
- 6203: The basic bearing designation, specifying a single row deep groove ball bearing with a 17 mm bore, 40 mm OD, and 12 mm width.
- 2RS1: Signifies that the bearing is fitted with two contact seals (one on each side), offering superior protection against contaminants and retention of lubricant.
- W64F: Denotes the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with oil, which is ideal for applications where relubrication is difficult or where grease washout is a concern.
W 6203-2RS1/W64F Bearing Structural Features & Performance Benefits
Corrosion Resistance: The all-stainless steel construction (rings, balls, and cage) ensures reliable operation in humid or corrosive environments, extending bearing service life.
Maintenance-Free Operation: The combination of 2RS1 contact seals and Solid Oil lubrication creates a sealed-for-life unit. This eliminates the need for relubrication, reduces maintenance costs, and prevents lubricant leakage.
Load and Speed Capability: Designed to handle radial dynamic loads up to 1812 lbf, it operates effectively at speeds up to 26,000 rpm. The ABEC 1 (ISO P0) tolerance class guarantees consistent and reliable performance for a wide range of industrial applications.
Temperature Stability: The Solid Oil lubricant and stainless steel materials allow for a stable operating temperature range from -30°C to +120°C.
W 6203-2RS1/W64F Bearing Typical Application Areas
This bearing is ideally suited for applications requiring corrosion resistance and minimal maintenance. Common uses include:
- Food and Beverage Processing Equipment
- Medical and Pharmaceutical Devices
- Chemical Handling Pumps and Mixers
- Marine and Washdown Environments
- Electrical Motors and Small Gearboxes
