Bearing Solutions for Port & Harbor Cranes and Equipment

Port machinery operates at high duty cycles with heavy shock loads, corrosive salt spray, and demanding uptime requirements.

Key Applications:

- STS & RTG crane travel mechanisms: Wheel shafts use double-row tapered Roller Bearings or Spherical Roller Bearings to absorb shock and misalignment.

- Hoisting mechanisms: Drum shafts use Spherical Roller Bearings; high-speed shafts use Cylindrical Roller Bearing plus Deep Groove Ball Bearing combinations.

- Slewing mechanisms: Portal cranes and bucket-wheel stacker-reclaimers use large three-row roller Slewing Bearings.

- Wire rope drums & sheaves: Deep Groove Ball Bearings or spherical roller bearings.

- AGVs & straddle carriers: Drive wheels and steering wheels use Hub Bearing units.

Selection Considerations:

Salt spray corrosion requires surface protection (zinc plating, Dacromet, or special coatings). Heavy shock loads call for bearings with designed radial clearance. High equipment utilization favors quick-change bearing units to minimize downtime.
