Product Overview: The QJ 214 Four-Point Contact Ball Bearing
The QJ 214 is a high-performance four-point contact ball bearing, engineered to handle complex load conditions within a compact design. With principal dimensions of 70x125x24mm, this bearing is part of our specialized Angular Contact Ball Bearings range. Its unique internal geometry, featuring a single outer ring with two gothic arch raceways, allows it to accommodate significant axial loads in both directions, as well as moderate radial loads. This makes it an excellent space-saving alternative to a matched pair of single-row angular contact bearings.
Manufactured from high-grade bearing steel, the QJ 214 provides exceptional durability and performance in demanding industrial applications. Its ability to manage bi-directional thrust loads makes it a crucial component in machinery where axial space is limited and operational reliability is paramount. Explore our complete selection to find the ideal bearing solution for your specific requirements.
Features of the QJ 214 Bearing
- Four-Point Contact Design: Enables the bearing to support axial loads from both directions and radial loads.
- Bi-Directional Axial Load Capability: Functions like a double-row angular contact bearing but requires significantly less axial space.
- High Load Capacity: Engineered to withstand heavy axial loads, providing stability and rigidity to rotating assemblies.
- Space-Saving: Replaces two separate bearings in many applications, simplifying the design and reducing housing dimensions.
- Separable Inner Ring: Often designed with a two-piece inner ring, which simplifies mounting and dismounting procedures.
