Product Description

SKF 6309-2Z/C3GJN 1 Row Deep Groove Ball Bearing features a 45 mm inside diameter, 100 mm outside diameter, and 25 mm race width designed for robust rotary applications. This shielded bearing reduces lubricant contamination and maintenance requirements.

Constructed with steel balls and a sheet metal cage, it offers durable performance with reduced mass for improved rotor dynamics. The C3 internal clearance compensates for thermal expansion, preventing preload during operation.

The bearing is rated with a static load capacity of 31.5 kN and a dynamic load capacity of 55.3 kN, making it suitable for continuous heavy-duty service at speeds up to 7500 rpm. Its cylindrical bore type suits a wide range of machinery requiring compact, reliable rotary bearings.

Industries using this bearing include industrial automation for motor shaft support, small rotating machinery spindles, gearbox intermediate shafts under radial loading, precision conveyor rollers in production lines, and cooling fans within electrical cabinets.

This bearing's shielded end protects against particulate ingress while permitting re-lubrication if accessible. The sheet metal cage reduces centrifugal effects to enhance high-speed performance. Steel balls provide durable contact surfaces for repeated operational cycles.

C3 clearance ensures thermal adaptation without inducing preload or bearing damage. Static and dynamic load ratings allow use under shock and continuous rotary loads.

SKF's 6309-2Z/C3GJN model balances reliability, longevity, and moderate-speed capability for diverse industrial, mechanical, and automation uses. This product category suits engineers seeking a trustworthy deep groove ball bearing solution with precise dimensional specifications.
