SKF Single Row Deep Groove Ball Bearing 45 mm ID, 100 mm OD, 25 mm Width, Shielded, Sheet Metal Cage 6309-Z/C5

SKF 6309-Z/C5 is a high-quality single row deep groove ball bearing featuring a 45 mm inside diameter, 100 mm outside diameter, and 25 mm race width. The bearing is shielded and built with a sheet metal cage, ensuring reliable retention of steel rolling elements and protection against contamination. Its C5 internal clearance allows for thermal expansion and lowers operational friction, making this bearing ideal for moderate speed and load applications.

This bearing supports a dynamic load rating of 55.3 kN and a static load rating of 31.5 kN, suitable for sustained operational loads and stationary load-holding requirements. With a limiting speed of 9,500 rpm, it is optimized for efficient rotation in industrial equipment.

Common applications include conveyor drive shafts in manufacturing lines, electric motor spindle supports at moderate speeds, gearbox shaft axial and radial support, pump and compressor bearing locations, and industrial fan and blower rotor assemblies.

The bearing employs a cylindrical bore for straightforward shaft mounting with press or slip fit. Sheet metal cage material ensures dimensional stability and even spacing of rolling elements under varying loads. The shielded design helps retain grease and reduce ingress of contaminants, thereby extending lubrication intervals.

The bearing’s shielded contact reduces contamination ingress and simplifies maintenance. Sheet metal cage guarantees secure retention of steel balls. C5 internal clearance allows for thermal growth and preload adjustments.

Dynamic and static load ratings enable performance under sustained and stationary conditions. Limiting speed rating up to 9,500 rpm supports efficient moderate-speed operation. Cylindrical bore facilitates easy installation on standard shafts.

Steel ball material provides durability and consistent rotation.

SKF Ball Bearings are engineered for industrial, manufacturing, HVAC, and mechanical applications requiring reliable radial and axial load support with controlled internal clearances. This model supports various rotating machinery, enhancing operational efficiency and lifetime reliability.
