Thin Section Four Point Contact Ball Bearings

1. Sizes: Inner Diameter: 150-480mm
Outer Diameter: 225-870mm, Weight: 5.1-470kg
2. Type: QJ, QJF
3. Feature: Four point contact ball bearings are separable bearings, in which, type QJ0000 has two piece inner ring, type QJF0000 has two piece outer rings, their contact angle are both 35°. When carrying pure radial loads, each ball cotacts with rings ar four point, and they are two point contact under pure axial loads. The bearings can carry axial loads in two directions and certain moment loads, and have the features of single row and double row angular contact ball bearings. They only can work normally in high speed when two point contact is formed.
4. Cage: Brass or aluminium soild cages are exactly suitbale for four point contact ball bearings.
5. Material: GCr15/GCr15SiMn/G20Cr2Ni4A
