Product Description
Four-point contact ball bearing is separable inner or outer ring (inner ring isolated QJ type for QJF type outer ring separation), can withstand two-way axial load. Inner and outer ring raceways are pointed arch-shaped grooves, both radially when pressed, theoretically and inner and outer ball four point contact, but generally applies to pure axial load or axial load large combined load of two point contact of the occasion. Cage for the high strength brass casting machined cage.
Four point contact ball bearings features
Four point contact ball bearings are separable structure, a single bearing can replace the front or back of a combination of a combination of angular contact ball bearings.
Few can bear radial load, axial load, can limit the axial displacement in both directions, but more than double row angular contact ball ball bearing specifications now occupied by the axial space.
Four point contact ball bearings compared to other ball bearing, when the same radial clearance, axial clearance is smaller, the higher speed limit.
Four point contact ball bearings designed to withstand pure axial load or axial load mainly axial, radial joint load. Because it is the double semi-inner (or outer), loading the number of balls increases, with a larger carrying capacity.
When under normal operating conditions, such bearings can withstand axial load in any direction, it can form a contact angle, the ball and the inner and outer raceway at the contact point, to avoid the occurrence of a large contact area of sliding friction. Therefore, the bearing should bear the main radial force and load.
Angular Contact Bearing
Feature
A, which can also bear radial and axial load or axial load
B, running resistance is small, the limit speed is high
C, high rotation accuracy
D, low noise and vibration
