W 629 Bearing Structural Features & Performance Benefits
This bearing features a single row deep groove raceway design that provides optimal radial load capacity while accommodating moderate axial loads in both directions. The all-stainless steel construction (rings, balls, and cage) ensures excellent corrosion resistance and makes it suitable for harsh environments. With a limiting speed of 40,000 rpm, it delivers reliable high-speed performance. The CN radial clearance and precise dimensional tolerances contribute to smooth operation and reduced vibration, enhancing overall system reliability.
