W 635-2Z Bearing Product Overview & Core Advantages
The W 635-2Z is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation and long service life. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle significant radial loads while its shielded (2Z) design retains factory-fresh grease lubrication, protecting against contamination and enabling maintenance-free operation. This makes it an ideal, compact solution for applications demanding precision and high reliability.
W 635-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| W | Stainless Steel Bearing Series | Indicates the bearing is manufactured from stainless steel, providing enhanced corrosion resistance. |
| 635 | Bore Size Code | Specifies the bearing dimensions: 5 mm bore, 19 mm outside diameter, 6 mm width. |
| 2Z | Shielded on Both Sides | Features non-contact shields on both sides to protect against contaminants and retain lubricant, enabling a maintenance-free design. |
W 635-2Z Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Single Row Design: The deep groove geometry of the inner and outer rings allows the W 635-2Z to accommodate not only high radial loads but also moderate axial loads in both directions, making it a versatile ball bearing choice.
Full Stainless Steel Construction: All components, including rings, balls, and the cage, are made from stainless steel. This ensures superior corrosion resistance, making the bearing suitable for harsh environments and applications requiring washdown.
Shielded & Pre-Lubricated: The 2Z shields effectively seal the bearing, preventing the ingress of dirt and moisture while retaining the high-quality grease. This combination provides long-term, maintenance-free operation and contributes to a long service life.
Precision & Speed: Manufactured to P0 tolerance class and featuring optimized internal geometry, this bearing ensures smooth running and is capable of operating at high limiting speeds up to 43,000 rpm.
W 635-2Z Bearing Typical Application Areas
The W 635-2Z is ideally suited for a wide range of applications where compact size, corrosion resistance, and reliable, maintenance-free operation are critical. Key sectors include:
- Medical and Dental Equipment: Small motors, pumps, and handheld tools.
- Food & Beverage Processing: Conveyor systems and machinery requiring frequent washdowns.
- Precision Instruments: Optical encoders, measuring devices, and small gearboxes.
- Electric Motors: Small fans, blowers, and auxiliary drives.
