Product Description
High Precision Angular Contact NTN Ball Bearing QJ306 Series With Less Coefficient Friction
Detailed Product Description
single row angular contact ball bearings can only support axial load in single direction, in bear radial load,will cause additional axial force,and can only limit the axial displacement of the shaft or housing in one direction.If pairs of double installation,the bearing outer ring relatively wide end face of wide and narrow end facing the narrow end.This can avoid additional axial force,and the shaft or housing to limit the range of the axial clearance in both directions.Angular contact ball bearing was more balls than deep groove ball bearing,so the load bearing capacity is the highest in all ball bearing,and it has strong rigidity,rotate stable.It can also through the inner and outer rings relative displacement on the radial clearance.
Quick Detail:
(1) have raceways in the inner and outer rings that are displaced with respect to eachother in direction of the bearing axis.
(2) This means that they are designed to accommodate combined loads, i.e, Simultaneously acting radial and axial loads.
(3) The axial load carrying capacity of increase with increasing contact angle.
(4) The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, transmitted from one raceway to another.And a line perpendicular to the bearing axis.
(5) Features:
1. Load capacities are higher than deep groove ballbearingof same dimensions.
2. Used forbearingradial-axial combined loads or pure thrust loads.
The size includes
(0)2 series and (0)3 series
