W 6204-2RS1 Bearing Product Overview & Core Advantages
The W 6204-2RS1 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-lubricated grease, providing long-term, maintenance-free operation by effectively excluding contaminants and retaining lubricant. This bearing is engineered to handle primarily radial loads and is characterized by its high limiting speed and reliable operation across a wide temperature range, making it an ideal choice for applications requiring durability and precision.
W 6204-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Meaning | Technical Significance |
|---|---|---|
| W | Stainless Steel Bearing | Indicates the bearing rings, balls, and cage are manufactured from stainless steel, providing excellent corrosion resistance. |
| 62 | Series Code | Denotes a medium-duty, deep groove ball bearing series with a specific dimensional relationship. |
| 04 | Bore Diameter Code | Specifies a 20 mm bore diameter (04 x 5 = 20 mm). |
| -2RS1 | Sealing Suffix | Signifies contact seals made of Nitrile Rubber (NBR) on both sides. This provides superior protection against dust, moisture, and other contaminants compared to non-contact shields. |
W 6204-2RS1 Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The use of stainless steel for all critical components (rings, balls, cage) ensures outstanding resistance to rust and corrosion, enabling reliable performance in harsh, wet, or chemically aggressive environments.
- Optimized Sealing with 2RS1: The low-friction contact seals on both sides effectively prevent the ingress of contaminants and the egress of grease. This design significantly extends bearing service life and enables maintenance-free operation.
- High-Speed Capability: The precision-ground components and optimized grease lubrication allow for a high limiting speed of 10,000 rpm, making it suitable for applications requiring rapid rotation.
- Robust Load Capacity: With a dynamic load rating of 2428 lbf and a static load rating of 1472 lbf, this bearing is capable of handling significant radial loads for its size, ensuring operational stability and longevity.
- Standard Internal Clearance (CN): The CN radial internal clearance is suitable for a wide range of common operating conditions and mounting fits.
W 6204-2RS1 Bearing Typical Application Areas
The W 6204-2RS1 is ideally suited for applications where corrosion resistance, sealed integrity, and high-speed performance are critical. Common industries and equipment include:
- Food and Beverage Processing Machinery (conveyors, mixers, pumps)
- Medical and Laboratory Equipment (centrifuges, small motors, diagnostic devices)
- Chemical Handling Pumps and Mixers
- Marine and Outdoor Applications (electrical actuators, small winches)
- General Industrial Machinery requiring maintenance-free operation in challenging environments.
