Four-point contact ball bearings

(four) point contact ball bearing is a single row angular contact ball bearing with double half inner ring or double half outer ring, which is a separable structure. This kind of bearing has the application characteristics of mounting bearings in pairs, which can bear bidirectional axial load and limit axial displacement in two directions, but it occupies less axial space than double row angular contact ball bearings of the same specification. Due to the double half inner ring (or outer ring), the number of steel balls installed increases, so it has a larger load-bearing capacity. The installation and disassembly of the bearing is also very convenient.
