FAQ

Frequently Asked Questions

What information is needed for bearing selection?
Please provide the application, bearing position, load direction and value, speed, dimensions or installation space, accuracy, temperature, lubrication and expected service conditions.

Is on-site support available?
It may be arranged after the technical need, location, schedule, safety conditions, responsibilities and related costs are confirmed.

Can CHG analyze a damaged bearing from photos?
Photos can support a preliminary review, but a reliable conclusion may also require operating records, installation data, lubricant information, measurements or the physical bearing.

Can CHG review a replacement for an obsolete bearing
Yes. Send the original model, manufacturer, dimensions, drawing, application and operating conditions for an interchangeability review.
