4 Point Contact Ball Bearing

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

4 Point Contact Ball Bearing: Your Comprehensive Guide

What is a 4 Point Contact Ball Bearing?

A specialized kind of bearing called a 4 Point Contact Ball Bearing is made to handle both radial and axial loads in various applications. The 4 point contact design, in contrast to conventional ball bearings, which typically accommodate radial loads, permits four points of contact between the ball and the raceway, accommodating higher axial loads in both directions. Because of this, it is ideal for applications that require robustness and high precision.

Key Features:

  • 4-Point Contact: Provides support for axial loads in both directions.
  • High Precision: Ensures smooth and reliable operation in demanding conditions.
  • Durability: Built to withstand high loads and harsh environments.
