W 6201-2RS1NR/W64F Bearing Product Overview & Core Advantages
The W 6201-2RS1NR/W64F is a single row deep groove ball bearing designed for exceptional reliability and performance in demanding applications. Constructed entirely from stainless steel for superior corrosion resistance, this sealed bearing is pre-lubricated with Solid Oil for maintenance-free operation. Its key advantage lies in its ability to handle significant radial loads while offering protection from contaminants. The inclusion of a snap ring on the outer ring simplifies axial location within a housing, making installation more efficient and secure. This combination of features makes it an ideal choice for applications requiring high precision, long service life, and minimal maintenance.
W 6201-2RS1NR/W64F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit / Description |
|---|---|---|
| W 6201 | Basic Bearing Designation | Standard single row deep groove ball bearing with a 12 mm bore, 32 mm OD, and 10 mm width. |
| -2RS1 | Seal Type | Fitted with two-contact rubber seals (RS) on both sides. Provides excellent protection against contaminants and retains lubrication. |
| -NR | Outer Ring Feature | Outer ring has a snap ring groove. This allows for simplified axial location and secure fitting in the housing, reducing assembly complexity. |
| /W64F | Lubrication | Pre-lubricated with Solid Oil (W64F). This polymer-based lubricant is permanently encapsulated, does not leak, and offers a long, maintenance-free service life across a wide temperature range. |
W 6201-2RS1NR/W64F Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings and balls are made from stainless steel, providing outstanding corrosion resistance, which is critical for use in humid, washdown, or chemically aggressive environments.
- Robust Sealing with 2RS1 Seals: The dual-contact rubber seals effectively shield the bearing's interior from dust, dirt, and moisture while securely retaining the Solid Oil lubricant, ensuring consistent performance and a long operational lifespan.
- Maintenance-Free Operation with Solid Oil: The integrated Solid Oil lubrication system eliminates the need for re-lubrication. It is ideal for applications where lubrication is difficult or impossible, and it performs reliably within a temperature range of -30°C to 120°C.
- High Radial Load Capacity: The deep groove raceway and precision construction enable the bearing to support a high radial dynamic load rating of 1286 lbf, making it suitable for applications with significant radial forces.
- Simplified Mounting with Snap Ring (NR): The snap ring groove on the outer ring allows for secure axial positioning, reducing the need for complex housing shoulders and locknuts, which streamlines the assembly process.
W 6201-2RS1NR/W64F Bearing Typical Application Areas
This bearing's combination of corrosion resistance, sealed design, and maintenance-free operation makes it suitable for a wide range of industries and equipment, including:
- Food and Beverage Processing Machinery: Conveyors, mixers, and pumps where washdowns and hygiene are paramount.
- Medical and Laboratory Equipment: Devices requiring smooth, quiet, and contamination-free operation.
- Chemical Handling Pumps and Mixers: Applications exposed to corrosive chemicals or vapors.
- Electrical Motors and Gearboxes: Especially smaller motors in appliances or industrial drives that benefit from sealed, long-life bearings.
- Agricultural Machinery: Equipment operating in dusty or wet outdoor conditions.
