RU178X Precision Crossed Roller Bearing 115x240x28mm for CNC & Robot Joints

Product Overview

The RU178X Crossed Roller Bearing is a high-rigidity, integrated-ring solution engineered for precision rotary motion. Featuring a specialized "X" type mounting hole configuration, this bearing allows for direct bolting to the mounting surface, eliminating the need for a press-fit housing. It is the industry standard for CNC rotary tables and industrial robotic joints requiring high tilting moment resistance.

Key Features
  • Integrated Mounting: Bolt-on design eliminates the need for housings or flanges.
  • High Rotation Accuracy: P2/P4 precision levels ensure minimal runout and stable positioning.
  • Dual-Direction Load: Handles radial, axial, and moment loads in a single compact unit.
  • Superior Rigidity: Crossed roller geometry provides 3-4x the stiffness of traditional ball bearings.
  • Plug-and-Play: Optimized for fast installation and high structural integrity.

FAQ
1. What is the difference between RU178, RU178G, and RU178X?
While dimensions are identical, the mounting holes differ: RU178X features tapped holes on the inner ring (12-M8), making it easier to bolt directly from the mounting surface compared to the through-hole versions.

2. Can this bearing handle high tilting moments?
Yes. The 90° V-groove raceway allows the rollers to handle complex tilting moments with much higher stability than standard ball bearings.

3. Do you provide 3D CAD files for integration?
Yes. GQZ provides STEP and IGES files for the RU178X to help engineers quickly integrate the bearing into their mechanical designs.
