Frequently Asked Questions

Q: Which materials are most suitable for high-vibration pipeline bearings?

For high-vibration environments, we recommend ductile iron (GGG series) or alloy steels like 42CrMo due to their superior toughness and fatigue resistance.

Q: Do you provide certifications for material composition and strength?

Yes, every shipment includes a detailed material report covering chemical contents, tensile strength, yield strength, and hardness.

Q: What is the typical process for a custom OEM bearing order?

The process starts with drawing review and design optimization, followed by wax injection, shell making, pouring, CNC machining, surface treatment, and final inspection.

Q: Can you handle complex surface treatments like electroless nickel plating?

Absolutely. We offer a wide array of finishes including electroless nickel plating, zinc plating, E-coating, and hot-dip galvanizing to meet corrosion requirements.

Q: How do you ensure the internal quality of the castings?

We utilize non-destructive testing (NDT) methods such as X-ray, Ultrasonic testing, and Magnetic particle inspection upon customer request to ensure zero internal defects.

Q: Do you offer sourcing services for other metal casting components?

Yes, we provide comprehensive sourcing services, including supplier assessment, price negotiation, and end-to-end logistics management for various casting needs.
