Industry-Proven Applications

1. Mining Crushers

Dual-purpose Sealed Tapered Roller Bearing sealing prevents rock dust ingress while retaining grease under 10g vibration loads.

2. Steel Rolling Mills

High-carbon chromium steel races withstand continuous 480°C furnace heat without deformation.

3. Port Cranes

Corrosion-resistant fluoropolymer seals endure saltwater spray in coastal container handlers.

4. Wind Turbine Gearboxes

P4-grade precision reduces vibration to <18dB at 1,500 RPM for stable power generation.

FAQ

Q1: How do your seals withstand abrasive dust in mining crushers?

Our triple-lip design uses a primary fluoropolymer barrier, secondary labyrinth channel, and tertiary grease-purged cavity to block 99.9% of <50μm particles.

Q2: Can you make bearings over 5000mm OD?

Yes! We’ve delivered φ5200mm custom products for bucket wheel excavators. Tolerances held to IT6/ISO 286.

Q3: What grease lasts longest in high-heat steel mills?

We pre-lubricate with lithium complex grease (NLGI 2, 300°C drop point) unless specified otherwise.

Q4: How do I monitor bearing health remotely?

Our IoT-ready bearings can embed sensors tracking temperature (±1°C accuracy) and vibration (0.1mm/s resolution).

Q5: Show me your ISO 281 dynamic load rating certificates.
