Product Description

 

VI160288-N model Four-point contact ball bearings

Four-point contact ball bearings can only form two points of contact to ensure normal operation. Therefore, it is generally applicable to those situations where there is two-point contact under the pure axial load or the composite load with large axial load, and the four-point contact ball bearing has high limit speed, and it is also suitable for those situations with high speed operation.

Under normal working conditions, such bearings can form a contact Angle when bearing axial loads in any direction, and the steel ball contacts with the inner and outer raceways at one point, avoiding large sliding friction in the contact area. Therefore, bearing should not be subjected to mainly radial force and load.
