W 626-2RS1/VT378 Bearing Structural Features & Performance Benefits
- Compact and Robust Design: The single row deep groove raceway and stainless steel construction provide a compact yet strong bearing solution, capable of handling the specified radial dynamic load rating of 344 lbf.
- Effective Sealing and Lubrication: The 2RS1 contact seals effectively protect against contamination and retain the factory-applied VT378 grease, enabling a maintenance-free service life and contributing to the bearing's limiting speed of 56,000 rpm.
- Precision and Stability: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, this bearing ensures smooth and consistent operation, minimizing vibration and noise.
- Corrosion Resistance: The use of stainless steel for the rings and balls makes the bearing suitable for applications exposed to moisture or corrosive environments, operating within a temperature range of -30°C to 120°C.
