FAQs
Crossed Roller Bearings FAQs
What crossed roller bearing series does CHG manufacture?
CHG manufactures RAU, RU, CRBH, RE, RB, SX and XSU crossed roller bearings for compact, high-rigidity and high-accuracy rotary applications.
What precision grades are available?
P5, P4 and P2 precision grades can be reviewed according to the series, size and application. Please state the required runout or accuracy class.
Can preload, mounting holes, seals or lubrication be customized?
Yes. These requirements can be evaluated according to series, size, speed, load, temperature and mounting arrangement.
What loads can a crossed roller bearing support?
The crossed arrangement enables one bearing to support radial, axial and moment loads simultaneously. Final selection depends on bearing size, load spectrum and mounting rigidity.
How do I choose between RAU, RU, CRBH, RB, RE, SX and XSU?
Selection depends on installation space, rotating ring, integrated or split-ring structure, mounting-hole requirement, rigidity and accuracy. Send the model or drawing for engineering review.
What information is needed for a quotation?
Please send the bearing number or drawing, ID / OD / width, mounting holes, rotating ring, accuracy, preload or clearance, radial/axial/moment loads, speed, application and quantity.
