Model: QGJ-0600
Outer Diameter: 1020mm
Weight: 780kg
Application: transmission of tunnel boring machines
The spherical plain bearing is designed for high load carrying capability and long service life under harsh working environments. Adopting this spherical plan bearing greatly improves the working efficiency and operational safety of tunnel boring machines.
- Strong load accommodation capacity: Designed with different bearing structure, the spherical bearing can accommodate both purely axial loads, radial loads, and combined radial and axial loads.
- Long service life: The bearing is constructed with 42CrMo which undergoes quenching and tempering after rough machining. In addition, it’s processed with surface phosphorification, spray coating, etc. These ensure long service life of the bearing in the demanding environments.
- High-performance materials: High-strength steels and other high-grade alloys are used to ensure the bearing works well under extreme operating conditions.
- Self Lubricating and Easy Maintenance: The spherical plain bearing is composed of an outer ring and an inner ring. Due to the sliding surface, it can freely rotate during movement at any angle. Because the composite material is inlaid on the outer spherical surface of the inner ring, the bearing can produce self-lubrication during operation. This results in ease of maintenance, reduced downtime, and lower maintenance cost.
At present, QGJ-0600 spherical plain bearings have been successfully applied to a number of large-scale tunneling projects, and have been highly praised by users. Luoyang Jiawei will continue to strengthen cooperation with the world's top 500 enterprises, continuously promote technological innovation, and provide better bearings and services for global customers.

Manufacturing Process
MoreAfter rough turning, the workpiece is detected by an ultrasonic flaw detector to examine cracks or other flaws and ensure the bearing’s stable quality and normal service life. Quenching and tempering can be conducted according to the requirements, to improve the strength and fatigue resistance of the material.
