W 636 Bearing Product Overview & Core Advantages
The W 636 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily accommodate radial loads and is characterized by its compact design with a 6 mm bore, making it ideal for space-constrained assemblies. Its open seal type allows for versatile lubrication options and facilitates high-speed operation, with a limiting speed of 48,000 rpm. Manufactured to P0 tolerance class with a standard CN radial internal clearance, it provides consistent and predictable performance for a wide range of industrial uses.

W 636 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments, including those with exposure to moisture or chemicals.
- High-Speed Capability: The open design and precision engineering minimize friction and heat generation, enabling a high limiting speed of 48,000 rpm for demanding applications.
- Radial Load Capacity: The deep groove raceway and single-row design are optimized to efficiently support significant radial dynamic (447 lbf) and static loads (175 lbf).
- Precision & Consistency: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing ensures smooth running, low noise, and vibration, which is critical for precision instruments.
- Versatile Lubrication: The open structure allows for easy cleaning and re-lubrication, enabling users to select the optimal lubricant for specific temperature ranges (-30° to 120 °C) and operational conditions.
W 636 Bearing Typical Application Areas
- Precision Instruments: Medical devices, optical encoders, and measuring equipment.
- Small Electric Motors: High-speed spindles in dental handpieces, miniature fans, and drones.
- Food and Beverage Processing Equipment: Where corrosion resistance and cleanability are paramount.
- Office Automation Equipment: Printers, scanners, and copiers.
