Product identity

This KBC 6309-2RS ball bearing is a single row deep groove unit measuring 45mm x 100mm x 25mm. It carries two contact seals and a C3 Fit rating for electric motor quality. Collectors and maintenance technicians seeking a specific KBC reference will find the exact dimensions they need.

Critical specification

The bearing is built with two contact seals and a C3 internal clearance suited to electric motor applications. That combination decides whether the part matches the original equipment requirement. Buyers who need an open or shielded variant, or a different clearance class, should look elsewhere.

Installation and common issues

Press the bearing squarely onto the shaft using a sleeve that contacts only the inner ring to avoid damaging the seals. Misalignment or hammer blows often ruin the contact seals and introduce premature noise. Ensure the housing bore matches the 100mm outside diameter for a proper interference fit.
