2309K-2RS-C3 Self-aligning ball bearing Two Seals C3

2309K-2RS-C3 The 2309K-2RS-C3 is a self-aligning ball bearing with a 45mm tapered bore (1:12 taper), featuring contact rubber seals on both sides for protection against contaminants. The C3 radial internal clearance provides greater operating clearance than standard, accommodating thermal expansion and misalignment in demanding applications. Self-aligning ball bearings are designed to compensate for angular misalignment between shaft and housing, making them suitable for applications where deflection or mounting errors occur. Common uses include agricultural equipment, conveyor systems, woodworking machinery, and other applications requiring tolerance for shaft misalignment or flexure.
