W 635 R Bearing Product Overview & Core Advantages
The W 635 R is a metric single row deep groove ball bearing engineered for precision and reliability in compact designs. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its open design facilitates high-speed operation, while its P0 tolerance class ensures consistent performance for applications requiring dependable radial load support. This bearing is an ideal solution for scenarios demanding a compact, corrosion-resistant, and high-speed component.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing series. |
| 635 | Indicates the specific bearing size (5mm bore, 19mm OD). |
| R | Signifies a flanged outer ring, which simplifies axial location and mounting within a housing. |
W 635 R Bearing Structural Features & Performance Benefits
- Flanged Design for Easy Installation: The integrated flange on the outer ring provides positive axial location, simplifying assembly and reducing the need for complex housing structures.
- High-Speed Capability: The open seal type minimizes friction, allowing the bearing to achieve a limiting speed of 56,000 rpm. The stainless steel cage ensures stability at high rotational velocities.
- Corrosion Resistance: Manufactured entirely from stainless steel, this bearing is suitable for applications exposed to moisture, chemicals, or demanding environments where corrosion is a concern.
- Precision & Reliability: Built to P0 tolerance class and standard CN radial internal clearance, this bearing delivers consistent and predictable performance for a wide range of general-purpose applications.
W 635 R Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Electric Motors and fans
- Precision Instruments and medical devices
- Office automation equipment such as printers and scanners
- Food processing and packaging machinery (benefiting from its stainless steel construction)
- Various light-duty machinery requiring a compact, flanged bearing solution
