SKF 626-2RSH/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 6x19x6mm

The SKF 626-2RSH/C3 sealed miniature deep groove ball bearing provides support for 6mm shafts in compact machinery where installation conditions require more than normal radial internal clearance. Its 19mm outside diameter and 6mm width suit small bearing housings, while the single row deep groove construction accommodates radial loads and limited axial forces in either direction. SKF specifications give a basic dynamic load rating of 2.34kN and a basic static load rating of 0.95kN. The bearing uses a stamped steel cage to separate and guide the rolling elements. Unlike the standard-clearance 626-2RSH, the C3 variant has greater internal radial play before mounting, helping accommodate clearance reductions caused by interference fits or temperature differences between the bearing rings.

The 2RSH contact seals protect both sides of the raceways and retain the factory grease, reducing the risk of contamination in equipment where regular relubrication is difficult. SKF catalogue data lists a limiting speed of 24,000rpm for this sealed design, although actual continuous operating suitability depends on load, temperature, lubrication and seal friction. Increased C3 clearance does not automatically make the bearing preferable for every high-speed application: the correct clearance must be selected according to the fitted assembly and operating conditions. With an approximate mass of 8.4g, the 626-2RSH/C3 offers a compact solution for applications requiring both contact sealing and additional internal clearance. During installation, apply mounting forces to the ring being fitted and avoid transmitting force through the balls.

Typical Applications:

Small electric motors with specified C3 clearance

Compact industrial fan and blower mechanisms

Miniature mechanical transmission assemblies

Automated equipment with tightly fitted bearing seats

Precision rotating equipment requiring sealed C3 bearings
