FAQs

Q: How do you prevent premature wear in abrasive environments?
A: Our ESA-86G steel undergoes deep cryogenic treatment to enhance surface hardness, ensuring the 22334 bearing lasts 50,000+ hours.

Q: How does your IoT monitoring work?
A: Embedded sensors track temperature and vibration trends in the bearing, sending alerts when parameters exceed safe thresholds.

Q: Do you offer samples for bearing bulk orders?
A: Yes—we offer an expedited sampling program with 7-day lead times for φ170-500mm units.
