Bearing 1306 NTN

DOUBLE-ROW SELF-ALIGNING BALL BEARINGS
A self-aligning ball bearing has two rows of balls sharing a common spherical raceway in the outer ring. This design allows the bearing to align itself and compensate for shaft misalignment relative to the housing. The bearing is ideal for arrangements where shaft deflection or misalignment may occur.
Bearing identification:
d: inner diameter (mm) of the bearing
D: outer diameter (mm) of the bearing
B: width (mm) of the bearing
