2209K-2RS-C3 Self-aligning ball bearing Two Seals C3

The 2209K-2RS-C3 is a self-aligning ball bearing with a 45mm tapered bore (1:12 taper), designed to accommodate angular misalignment between shaft and housing. It features contact rubber seals on both sides to retain lubrication and exclude contaminants, with C3 radial internal clearance for applications involving thermal expansion or interference fits.

Self-aligning ball bearings are commonly used in applications where misalignment from shaft deflection, mounting errors, or housing deformation is expected, including agricultural equipment, conveyor systems, woodworking machinery, and general industrial applications where precise shaft alignment cannot be maintained.
