W 608-2RS1/W64F Bearing Product Overview & Core Advantages
The W 608-2RS1/W64F is a sealed single row deep groove ball bearing engineered for high reliability in demanding applications. This precision bearing is characterized by its ability to accommodate significant radial loads and moderate axial loads in both directions. Manufactured entirely from stainless steel and pre-lubricated with Solid Oil, it offers excellent corrosion resistance and long-term, maintenance-free operation, making it an ideal choice for applications requiring durability and consistent performance.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| W 608 | Basic Bearing Series & Size | Denotes a standard metric deep groove ball bearing with an 8 mm bore, 22 mm OD, and 7 mm width. |
| 2RS1 | Sealing Type | Indicates the bearing is fitted with low-friction rubber seals (RS1 type) on both sides, providing effective protection against contaminants and retaining lubricant. |
| W64 | Lubrication Type | Specifies that the bearing is filled with Solid Oil (W64), a polymer matrix saturated with lubricant, eliminating leakage and offering a long service life. |
| F | Stainless Steel Material | Identifies that the bearing rings and balls are made from stainless steel, providing enhanced corrosion resistance. |
W 608-2RS1/W64F Bearing Structural Features & Performance Benefits
Robust Sealed Design: The incorporation of 2RS1 contact seals ensures superior protection against dust, moisture, and other contaminants. This sealing solution maintains internal cleanliness, significantly extending bearing service life and enabling reliable operation in harsh environments.
Maintenance-Free Operation with Solid Oil: The W64 Solid Oil lubrication is a key performance feature. It does not leak, drip, or harden, providing consistent lubrication throughout the bearing's lifespan. This eliminates the need for re-lubrication, reducing maintenance costs and downtime.
High Corrosion Resistance: Constructed entirely from stainless steel, this bearing is highly resistant to rust and corrosion, making it suitable for applications exposed to water, chemicals, or washdown procedures.
Precision and Speed Capability: Built to ABEC 1 / ISO P0 tolerance standards with a CN radial internal clearance, it offers reliable running accuracy. The optimized design and effective sealing allow for a limiting speed of 48,000 rpm, suitable for various high-speed applications.
W 608-2RS1/W64F Bearing Typical Application Areas
The W 608-2RS1/W64F is ideally suited for a wide range of applications where corrosion resistance, cleanliness, and minimal maintenance are critical. Key sectors include:
- Food and Beverage Processing Equipment (conveyors, mixers)
- Medical and Laboratory Devices
