Self-Aligning Ball

The inner ring has two raceways, while the outer ring has a spherical raceway with the curvature center of the spherical surface aligned with the center of the bearing. So, the inner ring, ball, and cage can tilt relatively freely towards the outer ring. Therefore, the deviation caused by the machining error of the shaft and bearing box can be automatically adjusted.

The inner ring tapered hole bearing can be installed with a locking sleeve.

Products Description

This type of ball bearings has two raceways in the inner and a common sphered raceway in the outer ring.It owns an inherent self-aligment property.That the angular misalignment permits within the range of 1.5° to 3° they are particularty for appolications in where misalignment that arised from errors in mounting or shaft deflection.

This type of bearings is mainly used to carry radial loads.At the same it can also carry a certain amount of axial loads.Although the loading capacity of this type of bearings is low yet it is subjected to high speed rotation.

Bearings of type 1000k with tapered bore (1:12)and with an adapter sleeve for definite position fixing on the smooth shaft are mainly used for the shaft without shoulder.Thid type of bearings is convenient if mounting and dismounting.Besides one can adjust the radial internal clearance.
