NTN Four-point contact ball bearings: 马来西亚的首选 ASIA INDUSTRY AUTOMATION SDN BHD

详情

Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported. The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.

Both inner ring halves of Explorer four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an cylindrical roller bearing. In addition, these recesses can be used to facilitate dismounting.

Features and benefits

Accommodates axial loads in both directions
Less axial space
These bearings take up considerably less axial space than double row bearings.
High load carrying capacity
A large number of balls are incorporated, giving the bearing its high load carrying capacity.
Separable design
The split inner ring leads to easier mounting and dismounting of the bearing.
Improved oil flow
Limited inner ring deformation when subjected to high clamping forces
