Built for High-Speed Challenges

1. Extreme Heat & Heavy Loads

Our bearings thrive in metallurgical environments where temperatures hit 150°C and shock loads exceed 20% of rated capacity. Specialized heat treatment and graphite lubrication prevent premature wear in steel rolling mills and blast furnace systems.

2. Precision in Motion

Medical-grade variants operate below 35dB noise levels with micron-level radial runout (≤0.005mm), ideal for MRI machines and high-speed centrifuges.

3. Agile Customization

Need non-standard dimensions? Our high speed cylindrical roller bearings modular design process adapts to unique shaft/bore fits in 15–20 days, supported by 12+ performance tests including vibration analysis and lifespan validation.

Quality Assurance Process

1. Material Inspection: Spectrometry checks for steel purity and hardness.

2. In-Process Controls: Laser measurement ensures dimensional accuracy within ±0.001mm.

3. Final Validation: Noise (<55dB), vibration, and load testing under simulated operational stress.

Every batch receives a traceable ID for accountability.

Global Supply Chain Excellence

Urgent Orders: 48-hour delivery for 1,000+ in-stock bearings.
Oversized Shipments: φ3000mm+ units shipped globally in 20 days.
Logistics Network: Regional hubs in Asia, Europe, and North America minimize transit times.

FAQ

Q: How do your bearings handle sudden load spikes in rolling mills?

A: The SHOCKPRO series incorporates reinforced roller ends and 20% overload capacity, absorbing impacts without performance loss.

Q: What lubrication works best for 500°C smelting applications?

A: High-temperature graphite-based lubes or ceramic hybrid designs prevent grease degradation.

Q: Can you modify bearings for existing machinery?

A: Yes! Share your operational data (speed, load, temperature), and we'll map a retrofit solution in 72 hours.

Q: How does IoT predictive maintenance work?

A: Embedded sensors monitor vibration and temperature, alerting you to lubrication needs or alignment issues before failures occur.
