Overview
This high-performance deep groove ball bearing is engineered for demanding industrial applications requiring precise rotational movement and heavy load capacity. Constructed from hardened steel, the unit delivers exceptional durability and resistance to wear in continuous operation environments. The design incorporates C3 internal clearance, which specifically accommodates thermal expansion during high-speed rotation or under significant radial loads, preventing premature failure due to heat buildup. Dual rubber seals on both sides provide a robust barrier against dust, dirt, and moisture while effectively retaining lubrication within the raceway. This configuration ensures reliable performance with minimal maintenance requirements, making it an ideal component for extending the service life of critical machinery such as electric motors, gearboxes, and centrifugal pumps.
Key Features
Hardened steel construction for maximum structural integrity and wear resistance C3 internal clearance optimized for high-speed operations and thermal expansion Dual rubber seals offering superior protection against contaminants and grease loss Precision-ground raceways ensure smooth rotation and reduced friction coefficients Designed for heavy radial load capacity with moderate axial load support Low noise and vibration levels suitable for sensitive industrial equipment Extended service life reduces downtime and total cost of ownership
