Frequently Asked Questions (FAQ)
Q1: What is the difference between G10 and G20 tolerance?
A: G10 (±0.025mm) is tighter than G20 (±0.050mm), making it suitable for high-precision applications like aerospace bearings.
Q2: Can GCr15 steel balls be customized?
A: Yes. We offer custom diameters, coatings (e.g., chrome plating), and packaging.
Q3: How does GCr15 compare to 440C stainless steel?
A: GCr15 has higher hardness and wear resistance, while 440C offers better corrosion resistance.
Q4: What industries benefit most from G10-grade balls?
A: Automotive, aerospace, medical devices, and precision engineering.
