FAQ
Q: Can your products handle continuous 150°C operations?
A: Yes. Our HT Series uses ceramic coatings and ZR19 alloy for thermal stability.
Q: How do you customize bearings for high-speed port machinery?
A: We modify cage designs, use hybrid ceramic balls, and enhance sealing for wear resistance.
Q: What tests ensure P4 precision for medical use?
A: Each batch undergoes vibration analysis, noise testing, and ISO 14644-1 cleanliness checks.
Q: Do you offer certifications like ASTM or CE?
A: Yes. We provide pre-certified batches for urgent orders and region-specific compliance support.
