Frequently Asked Questions
Q: What is the difference between G10 and other tolerance grades?
A: G10 represents tighter dimensional tolerances compared to standard grades. For example, G100 balls have ten times the diameter variation allowance of G10 balls.
Q: Can you provide custom sizes outside the 13mm-25mm range?
A: Yes, we can manufacture custom sizes upon request. Please contact us to discuss your specific requirements.
Q: What packaging options are available?
A: We offer various packaging solutions including bulk containers, plastic tubes, and custom packaging based on your needs.
Q: How does GCr15 compare to 440C stainless steel for ball applications?
A: GCr15 offers superior hardness and wear resistance, while 440C provides better corrosion resistance. The choice depends on your specific application requirements.
Q: What is the lead time for orders?
A: Standard sizes are typically available for immediate shipment. For large or custom orders, lead times vary based on quantity and specifications.
