Where Taper Roller Thrust Bearings Excel?

1. Mining & Metallurgy

In jaw crushers and rolling mills, our bearings absorb shock loads while resisting abrasive dust. A steel plant reduced replacement costs by 40% after switching to our P4-grade bearings with surface-hardened rollers.

2. Heavy-Duty Gearboxes

Positioned at thrust ends, they maintain alignment under fluctuating loads. A gearbox manufacturer achieved 18+ months of service life in 24/7 cement production.

3. Port Machinery

Custom seals and corrosion-resistant coatings protect against saltwater exposure, extending maintenance intervals by 60%.
