Why Choose Us?

Precision Engineering for Extreme Loads

Designed with dual-row angular contact steel balls and a brass cage, these bearings handle bidirectional axial loads and slight radial forces without requiring complex pairing. Their intermediate washer with dual raceways ensures even stress distribution, making them ideal for:

High-speed machine tool spindles requiring ≤0.01mm axial clearance.
Port cranes exposed to shock loads up to 500 kN.
Steel rolling mills operating at 200°C+ with minimal lubrication degradation.

Built to Last in Harsh Environments

We use GCr15/GCR15SIMN steel for shaft and intermediate washers, paired with heat-treated angular contact balls, to achieve:

Wear resistance: 30% longer lifespan than standard bearings in dusty mining setups.
Impact resistance: Stable performance under 50G acceleration in agricultural machinery.
Temperature resilience: Consistent operation from -30°C to +150°C.

Customization Without Compromise

Need non-standard dimensions or enhanced load capacity? We adjust:

Size: Inner diameter (20–200mm), outer diameter (50–280mm standard; up to φ5000mm custom).
Material: Upgrade to 20Cr2Ni4A alloy for corrosive offshore wind turbine applications.
Precision: P4-grade options for aerospace auxiliary systems requiring ≤35dB noise levels.

Where Our Bearings Excel?

Heavy Industry Solutions

Metallurgy: Bearings for continuous casting machines with high-temperature stability (150°C+).
Mining: Corrosion-resistant designs for underground conveyors handling 10,000+ hourly cycles.
Port Machinery: Low-noise, high-impact units for crane slewing rings (≤40dB).

Precision-Driven Sectors

Aerospace: Vacuum-grade lubrication for satellite components exposed to -60°C to 150°C swings.
Medical Equipment: Ultra-precise P4-grade bearings for MRI scanner positioning systems.
EV Manufacturing: Lightweight aluminum cages for 20,000 RPM+ drivetrains.

Quality You Can Trust
