Where Our Double Direction Thrust Ball Bearings Excel?

1. Metallurgical Furnace Conveyors

Withstand 500℃ temperatures and heavy axial loads in continuous operations. Our heat-treated steel and aligned raceways prevent deformation under thermal stress.

2. Port Machinery Cranes

Absorb shock loads from dynamic lifting while maintaining alignment. Corrosion-resistant coatings (e.g., carbide plating) protect against saltwater exposure.

3. Mining Crushers

Durable designs combat abrasive wear. Modular cages and hardened steel balls extend lifespan in high-impact environments.
