CHG is an enterprise majored in research and development, production and sales of accuracy bearings. According to the needs of users, the company has developed high-accuracy, high-performance, high-quality cross roller bearings used on industrial robots. The company can produce RAU, RB, RE, RU, CRB/CRBC, CRBH, SX, XSU, XU series of cross cylindrical roller bearings and XR, JXR series of cross tapered roller bearings with the accuracy of Grade P2.
The products are widely used in industrial robots, CNC machine tools, reducers, printing machinery, medical equipment, accuracy measurement and control equipment, communication radar antennas, optical equipment, and etc. Adhering to the concept of “Collect Elites and Develop Boutique”, our company is committed to providing customers with high quality products.
CHG has a technical team with more than ten years of research and development experiences for bearings, and they have achieved the outstanding results and many patents in design, manufacture and detection of uniform-section thin-section bearings, thin-section cross roller bearings, large accuracy high-speed ball bearings, military bearings and other accuracy bearings. The company always focuses on the modern management model, and has passed the certification of ISO9001: 2008 quality management system. According to customer requirements, can be tested by SGS, ASIA or other third-party international testing organizations.
Types of Cross Roller Bearings
There are several types of cross roller bearings, each designed to fit different rotation and mounting needs. Here are some common ones:
Type Description Best For Split Outer Ring (CRBA) Outer ring split into two halves; inner ring solid Inner ring rotation Split Inner Ring (CRBB) Inner ring split into two halves; outer ring solid Outer ring rotation High Rigidity Type (CRBC) Solid construction for extra stiffness Both rings rotating, high load Split Outer Ring with Mounting Holes (CRBD) Split outer ring with holes for easy fixing Inner ring rotation, fixed mount High Rigidity with Mounting Holes (CRBE) Solid rings with mounting holes Both rings rotating, fixed mount Customized Type (CRBX) Tailored design and surface treatments Special environmental needs
Applications of Cross Roller Bearings
Cross roller bearings are everywhere when precision and load capacity are needed in a compact space. Here are some cool examples where I’ve seen them used:
Robotics: For smooth, precise joint movements.
Machine Tools: Spindle heads in milling machines and lathes for accurate cutting.
Medical Equipment: Devices like CT scanners and surgical robots.
Industrial Automation: Pick-and-place machines and assembly robots.
Optical Telescopes & Radars: Where stability and accuracy are critical.
Turntables & Theater Equipment: Smooth rotation with minimal vibration.
