White Metal Bearing repairs by centrifugal casting

Facing White Metal Bearing Failure?

Bearing Repairs by Centrifugal Casting or Laser Cladding

We specialize in complete repair of white-metal bearings used in marine propulsion systems. This includes centrifugal casting / rebabbiting of new white-metal layers or laser cladding, depending on the bearing type and wear condition. We repair all types of white metal bearings, including:

• Stern tube bearings
• Intermediate bearings
• Thrust bearing pads
• Cederval seal boxes

All repairs are performed by class-approved methods and delivered with comprehensive documentation.

Bearing Repair Process

Our bearing repair process is class-approved and ensures precise restoration to original specifications. We conduct:

• Inspection and dimensional control with the classification society
• Blue-fit and machining of bearing housings, if necessary
• Ultrasonic testing of bonding (third-party certified)
• Renewal of white-metal using laser cladding or casting
• Final machining of inner diameter and seal grooves
• Control measurements and complete documentation

Our service scope includes worldwide inspection of damage to white metal bearings. After completing the repair at our Hirtshals workshop, we can assist with onboard installation and alignment, ensuring seamless reintegration of the repaired bearing into your propulsion system.

Intermediate Bearing Failure – In-Situ and Workshop Repair

While anchored off the coast of Thailand, a cargo vessel suffered an intermediate bearing failure. MarineShaft mobilized engineers for on-site inspection and immediate repair, followed by workshop machining in Denmark.
