1:Defination
Four-point contact ball bearing is a separation of bearings, it can be said of a two-way bearings can withstand axial load of angular contact ball bearings.The inner and outer raceway is peach-type section, when no load or a pure radial load, the balls and rings appear as four-point contact, which is the origin of the name; when only pure axial load. When the two steel balls and rings become exposed, can withstand a two-way axial load. Four-point contact ball bearings can withstand torque loads, both the single row angular contact ball bearings and double row angular contact ball bearings features. Only four-point contact ball bearings in contact to ensure the formation of two normal work. It is generally applied to those of pure axial load or axial load large synthetic loads where contact was two, four point contact ball bearings high speed limit, but also for those high-speed operation of the occasion.
2:Feature
a.Four-point contact ball bearings are separable structure, a single bearing can replace the front or the back of the portfolio combined angular contact ball bearings.
b.Can bear radial load, two-way axial load, to limit the axial displacement in both directions, but the specifications than the current golf ball bearings double row angular contact axial occupy less space.
c.Four-point contact ball bearings and other ball bearing, radial clearance when the same, the axial clearance small, high speed limit.
d.Four-point contact ball bearings for under pure axial load or axial load to mainly axial, radial joint load. As a dual semi-inner (or outer), put the ball in number and have greater carrying capacity.
