Industry-Proven Performance

Metallurgy & Steel Plants

Our large slewing bearings handle 500℃ furnace rotations with zero thermal warping, backed by induction-hardened rollers and high-temp grease.

Port Machinery & Offshore Cranes

Salt-spray tested for 1,000+ hours, these bearings prevent corrosion while supporting 50-ton loads in container handlers and ship loaders.

Mining & Heavy Construction

Reinforced structures absorb shock loads up to 3,000 kNm, while triple-lip seals block abrasive dust in excavators and tunnel boring machines.

FAQ: Large Slewing Bearings

1. Can you produce bearings larger than φ5000mm?

Yes! We engineer non-standard large slewing bearings up to φ6000mm using modular forging techniques.

2. How do you ensure corrosion resistance in port environments?

We apply zinc-nickel coatings and use fluororubber seals, tested for 1,000+ hours in salt-spray chambers.

3. What’s the lead time for a φ4000mm custom bearing?

Just 18-22 days – 30% faster than industry standards due to our agile production lines.

4. Do you provide load test reports?

Yes. Every bearing includes a certificate with dynamic/static load data and torque values.

5. Can your bearings integrate with IoT systems?

Absolutely. We embed sensors for real-time health monitoring via our cloud platform.
