1308 K 40 mm Bore Size, 90 mm Outside Diameter, Radial Ball Bearing, Self-Aligning, Tapered Bore, 52100 Bearing Steel, Normal Radial Clearance

The 1308K is a self-aligning ball bearing with a tapered bore (1:12 ratio) and 40 mm bore diameter from the 13 series. The double-row design allows the bearing to compensate for shaft deflection and misalignment between shaft and housing, making it suitable for applications where precise shaft alignment is difficult to maintain.

Self-aligning ball bearings are commonly used in agricultural machinery, conveyor systems, textile equipment, and woodworking machinery where shaft deflection or mounting errors are present. The tapered bore facilitates direct mounting on tapered shafts or mounting with adapter sleeves on cylindrical shafts.
