Custom Process
Standard Custom Bearing Process
1
Requirements Review
We confirm the application, bearing type, dimensions, load, speed, temperature, lubrication, accuracy and quantity.
2
Engineering Design
Our engineers evaluate the bearing structure, materials, clearance, cage, lubrication and key technical parameters.
3
Sample & Validation
Samples are manufactured and inspected according to the confirmed drawing and agreed validation plan.
4
Batch Production & QC
After sample approval, production is controlled from raw material and heat treatment to machining, assembly and final inspection.
5
Delivery & Technical Support
Products are delivered as agreed, with installation, lubrication and operating support available when required.
6
Feedback & Improvement
Operating feedback is reviewed to optimize the bearing design, manufacturing process and future supply.

FAQ
Frequently Asked Questions
Can CHG develop a bearing without a complete drawing?
Yes. Send the existing model, key dimensions, original bearing photos and operating conditions. Our engineers can first evaluate the available information.
Can a sample be produced before batch production?
Yes. Sample production and validation can be arranged after the technical requirements and drawing are confirmed.
What types of bearings can be customized?
CHG reviews custom projects for rolling mill, precision ball, thin section, crossed roller and slewing bearings, as well as rolling elements.
How is the lead time determined?
Lead time depends on bearing type, size, materials, validation requirements and quantity. It is confirmed after technical review.
