The four point contact ball bearing is a separable bearing, which is a set of angular contact ball bearings that can withstand bidirectional axial loads. The inner and outer raceway have a peach shaped cross-section. When there is no load or pure radial load, the steel ball contacts the ring at four points. Under pure axial load, the steel ball contacts the ring at two points and can withstand bidirectional axial loads. This type of bearing can also withstand torque loads and has the function of single row and double row angular contact ball bearings. This type of bearing can only ensure normal operation when it forms two-point contact. But it is generally suitable for two-point contact under pure axial load or composite load with large axial load. This type of bearing has a high limit speed and is suitable for high-speed operation. Usually used on mechanical equipment, robots, and precision instruments.
We specialize in producing and supplying various types of heavy-duty industrial roller bearings: four column rolling mill bearings, split bearings, self-aligning roller bearings, tapered roller bearings, thrust self-aligning roller bearings, and cylindrical roller bearings. Suitable for large mechanical equipment such as metallurgical steel rolling, mining crushing, engineering machinery, reducers, papermaking, ships, fans, etc., supporting standard models in stock and non-standard customization, providing original factory quality and testing reports, and supporting foreign trade exports.
