FAQs

Q: How do your angular contact thrust ball bearings maintain P4 precision at high temperatures?
A: We use heat-stable alloy materials like GCr15SiMn and advanced heat treatment to minimize thermal expansion in heavy-duty bearing applications.

Q: Can you make thrust ball bearings larger than φ5000mm?
A: Yes! Our modular production system supports custom bearing sizes up to φ5000mm with a 20-day lead time.

Q: What tests ensure low noise (<35dB) in medical device bearings?
A: Each angular contact thrust ball bearing undergoes vibration spectrum analysis and noise profiling in soundproof chambers.
