FAG four-point contact ball bearing is a separate type of bearing can also be said that a bearing angular contact ball bearings can withstand a two-way axial load. And row angular contact ball structure, compared with two-column design, the space required considerably less, but its outer ring and inner separation. The inner and the outer ring raceway peach cross section, when the no-load or pure radial loads, ball and ring rendered as a four-point contact, this is also the name of the origin; when only pure axial loads , balls and rings became a two-point contact, can withstand a two-way axial load.
FAG four point contact ball bearing pairs of semi-inner ring, so you can load as much ball. The outer component with a ball and half inner ring can be independently installed, bearings Self-aligning ability of such imports is very small.

FAG four point contact ball bearings can withstand high loads in the axial direction in both directions under low loads in the radial direction only. In order to ensure low friction, especially at high speed, requiring a minimum axial load.FAG bearing
FAG four point contact ball bearings can withstand torque loads, both the single row angular contact ball bearings and double row angular contact ball bearings. Only the formation of two contacts in order to ensure the normal work. Generally applicable to pure axial load or axial load of synthetic load was two-point contact of the occasion, four point contact ball bearing high speed limit, also suitable for high-speed operation of the occasion.
As the number of balls and shaft shoulder and the contact angle of 35 °, FAG four point contact ball bearing axial load carrying capacity is high. FAG four-point contact ball bearing as the thrust bearing, great with the gap left between the bearing and the bearing out er ring, to ensure that the radial force.thrust roller bearings
