FAQ

What is 100Cr6 bearing steel ball mainly used for?

100Cr6 bearing steel balls apply to rolling bearings, linear guides and precision machinery. They deliver stable hardness and wear‑resistance for medium‑load industrial rotating equipment.

What hardness level can 100Cr6 bearing steel balls reach?

Properly heat‑treated 100Cr6 steel balls achieve HRC 60‑66 hardness. This high hardness helps resist surface abrasion and maintains shape under continuous mechanical operation.

What size ranges do you supply for 100Cr6 bearing steel balls?

Our 100Cr6 bearing steel balls cover small to large diameters from 1mm up to 50mm. Custom sizes and grade adjustments are available to match different customer drawing requirements.

How about the surface quality of your 100Cr6 bearing steel balls?

Our 100Cr6 bearing steel balls have fine polished surfaces with few defects. Strict surface inspection reduces surface pits and scratches to lower running noise in finished bearing assemblies.

Can 100Cr6 bearing steel balls work in high‑temperature conditions?

100Cr6 steel balls fit normal working temperature below 120℃. Long‑time high‑temperature environments will decrease hardness; choose alternative materials for over‑temperature scenarios.

What tolerance grades are available for 100Cr6 bearing steel balls?

We produce 100Cr6 bearing steel balls in G5‑G100 tolerance grades. Higher‑grade balls provide better roundness, suitable for precision instruments and high‑speed bearing application scenarios.

What packaging options do you offer?

We offer multiple packaging options, including cartons, steel drums and bulk bags. Customized packaging is available based on customer requirements.

Can you help select the right grade for our application?

Yes, we can recommend suitable precision grades based on your application, load conditions and performance requirements.
