W 626 R Bearing Product Overview & Core Advantages
The W 626 R is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This metric bearing is engineered to primarily handle radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. Its open design allows for versatile application-specific lubrication, while its standard CN radial internal clearance and P0 tolerance class ensure reliable operation for a wide range of general-purpose applications.

W 626 R Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bearing width of only 6mm and a total weight of 0.0082 kg, this bearing is ideal for applications with severe space and weight constraints.
- High Corrosion Resistance: The use of stainless steel for all critical components (rings, balls, cage) ensures long-term performance in humid or corrosive environments, complying with ROHS and REACH standards.
- Simplified Mounting: The integrated flange (22mm outer diameter, 1.5mm thickness) facilitates easy and secure axial location within a housing, reducing assembly time and complexity.
- Broad Operating Range: Capable of operating within a temperature range of -30°C to 120°C, this bearing is suitable for various industrial conditions.
- Open for Custom Lubrication: The open seal type allows engineers to select the optimal lubricant (grease or oil) for specific speed, temperature, and lifetime requirements.
W 626 R Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., Printers, Scanners)
- Robotics and Small Actuators
