Q1: What is G10 grade?

A1: G10 is ultra-high precision grade. It has extremely small diameter variation and sphericity error, designed for high-precision miniature bearings.

Q2: What material are these balls?

A2: GCr15 / AISI52100 bearing steel, the most common bearing steel with high hardness and good wear resistance.

Q3: Can they be used for high-speed rotation?

A3: Yes. G10 precision guarantees small runout and stable performance for high-speed micro rotating assemblies.

Q4: How about anti-rust?

A4: We apply anti-rust oil on surface. Please keep them dry during storage. They are not corrosion-resistant stainless steel.

Q5: What inspection standard do you follow?
