Customizable Four-point contact ball bearing

High load capacity: a good many balls can be placed into the bearing to achieve higher load capacity. Separation-type design: separable inner ring can contribute to mounting and dismounting of bearings more conveniently. Four-point contact ball bearings such as 4P305AB and 4P306AB produced by Zhonglun can be used in the steering system of the automobile industry.

Customizable Ultra-high Speed Integrated Bearing

Product details

Four-point contact ball bearings are angular contact ball bearings that can support two-way axial loads. Four-point contact ball bearings are generally designed for scenarios like pure axial load or two-point contact circumstances under synthetic load( more axial loads). The high limiting speed of four-point contact ball bearings prepares them for the high-speed operating environment.

Four-point contact ball bearings can withstand axial loads in two directions and take up less axial space. And these bearings occupy significantly less axial space compared with double-row ones.
