The high cost of shaft removal and replacement

When engineering bearings fail, it usually results in a damaged shaft. Whether the shaft is in land-based processing plant or onboard a ship, new bearings can be ordered and installed relatively easily. Shafts, however, are harder to replace, a process that typically involves stripping out a machine or a gearbox just to remove the shaft. Next, the damaged shaft must be transported to a repair facility before the process is repeated in reverse and the shaft is eventually replaced. In the meantime, someone will be facing high costs for removal, transport, repair, installation of the repaired shaft and lost production (or availability of a vessel).

Save money with a cost-effective in situ repair

Metalock Saudi Arabia can help reduce these costs with cost-effective, accurate in situ repairs that reduce expensive downtime and get your equipment earning money again as soon as possible. All we need from you are a few simple technical details:

  • A datum point from which to set our equipment.
  • The correct parent metal specification so we can determine which weld or metal spraying procedure to adopt.
  • A detailed drawing of the component.

Typical repair methods

During the repair, the shaft remains static while the tool rotates around the shaft. Depending on the exact nature of the repair, we'll probably use one of the following methods:

  • Orbital machining with superfinishing (generally used when salvaging crankshafts on large marine diesel engines.
  • Orbital machining/shrink-on-sleeve/final orbital machine.
  • Orbital machining/orbital welding/final orbital machining.
  • Orbital machining/metal spraying/final orbital machining.

(We can also make similar repairs in reverse on worn bore locations using our in-situ boring equipment.)

A versatile repair service that saves you time and money

The same techniques also lend themselves to the repair of worn or damaged bore locations using our in-situ welding and boring equipment. It all adds up to a versatile service with many advantages over traditional repair methods:

• Speed of repair
• Lower removal, transport and replacement costs
• Lower downtime costs
