1307 K 35 mm Bore Size, 80 mm Outside Diameter, Radial Ball Bearing, Self-Aligning, Tapered Bore, 52100 Bearing Steel, Normal Radial Clearance

The 1307K is a self-aligning ball bearing with a tapered bore (1:12 taper) and 35 mm bore diameter. This double-row design accommodates angular 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, woodworking equipment, and textile machinery where shaft deflection or mounting errors occur. The tapered bore allows direct mounting onto tapered shafts or use with adapter sleeves on cylindrical shafts.
