Dentail
Thin-walled Design
-Materials often include high-strength alloy steel or ceramics to ensure sufficient rigidity and load capacity despite the thin walls.
Constant Cross-section Structure
-Facilitates standardized production and reduces manufacturing costs.

Working Principle

-Angular contact design allows bearings to handle combined loads during rotation, requiring paired installation (e.g., back-to-back or face-to-face) to balance axial forces.
Application
The bearings can be used in the following industries
  • Aerospace: Aircraft engines, missile guidance systems, and other weight-sensitive components.
  • Precision Instruments: Optical devices, measuring instruments, and semiconductor manufacturing equipment.
  • Robotics & Automation: Joint bearings and high-precision transmission systems.
  • Medical Equipment: Surgical robots and rotating parts in MRI machines.
  • Industrial Machinery: High-speed motors, machine tool spindles, and scenarios requiring high rigidity and compact design.
