Frequently Asked Questions (FAQ)
Q: What does G10 tolerance mean for steel balls?
A: G10 indicates diameter variation ≤ 0.0005″ (0.0127mm), making these balls suitable for high-speed precision bearings.
Q: Can you supply GCr15 balls with different surface treatments?
A: Yes, we offer phosphating, black oxide, and zinc plating for enhanced corrosion protection.
Q: What’s the lead time for custom diameter orders (13mm–25mm)?
A: Standard sizes ship in 3-5 days; custom diameters typically require 2-3 weeks.
Q: How do GCr15 balls compare to stainless steel alternatives?
A: GCr15 offers superior hardness and load capacity, while stainless steel provides better corrosion resistance at lower hardness levels.
