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
Product Description

4 Point Contact Ball Bearing - Premium Engineering Solution for Heavy-Duty Applications

When your industrial equipment demands exceptional performance under extreme conditions, you need a bearing solution that delivers reliability and precision. Our 4 point contact ball bearing arrangement that conveys unwavering quality and accuracy. Our 4 point contact ball bearing speaks to the apex of building brilliance, planned to handle both spiral and pivotal loads with unmatched effectiveness. These specialized heading include four particular contact focuses between balls and raceways, giving prevalent stack dispersion and expanded benefit life for your basic apparatus applications.

What Makes Our 4 Point Contact Ball Bearing Special?

Advanced Design Technology

Our heading include a interesting distinct plan with two inward ring parts (QJ sort) or two external ring parts (QJF sort). This imaginative development permits for simple establishment and support whereas keeping up basic keenness beneath requesting conditions.

The 35-degree contact point guarantees ideal stack dealing with. When carrying unadulterated spiral loads, each ball makes four contact focuses with the rings. Beneath immaculate hub loads, the framework works with two contact focuses, giving momentous flexibility for your particular application needs.

Superior Load Capabilities

You'll appreciate how these bearings excel in handling:

  • Bidirectional pivotal loads - Culminate for hardware encountering strengths from numerous directions
  • Combined outspread and hub loads - Perfect for complex apparatus operations
  • Moment loads - Basic for applications requiring rotational stability
  • High-speed operations - Built for effectiveness when two-point contact is established
