Product Description

1) Contact angle is classified as C(15°), AC(25°) and B(40°)
2)four-point-contact ball bearings are also single row angular
Contact ball bearings, which require significantly less space in an axial direction than double row designs
3)Most have nylon 66 cage, but pressed steel cage can be supplied for some types.
4)B. C. AC. QJ series model available in competitive price with good price

Four Point Contact Ball Bearing(with Two-piece lnner Ring)

Four point contact ball bearings are single row having raceways that enable to accommodate axial loads in both directions. They need lesser axial space and a two part inner ring. This allows large number of balls to be incorporated and carry larger loads. The bearings are separable type. They are designed to accommodate axial loads and arranged as thrust bearings with radial clearance.

Four point contact ball bearings is separable bearing, owning two-piece inner ring or outer ring. its contact angle is 35 °. There are four points contact between steel ball and rings. Four point contact ball bearings can endure radial load, axial load and the combined load (axial load and radial load). This type of bearing can limit the displacement of two radial directions between the shaft and housing. We classify it by its structure .they are QJ and QJF this two kinds. Four point contact ball bearings enjoy big load capability and high rotate speed. They can support the bidirectional load. They own the both character which single row enjoyed and double row enjoyed. Four points contact ball bearing is suitable to mill machines, spindle shaft for machine tools. And printing machines etc
