30234 Tapered Roller Bearing


  • Dimensions: 170mm (d) x 310mm (D) x 57mm (T)
  • Superior kinetic energy absorption for rapid cargo lifting.
  • Locks wire rope drums into perfect axial alignment.
  • High-grade fatigue resistance cuts maintenance costs in busy ports.

Maritime logistics hubs rely on massive grab cranes to unload bulk cargo carriers at breakneck speeds. The 170mm bore 30234 bearing is built into the core hoisting winches to absorb the intense shock load that occurs the exact moment a 40-ton grab lifts off the ship's hold. By maintaining absolute dimensional alignment under extreme wire rope tension, it prevents drum wobbling and safeguards the main braking gears from destructive shearing forces.
