On-Site Journal Machining & Honing

On-Site & In-Situ Journal Machining & Honing

Many different types of equipment have some form of shaft rotating in a bearing. Over time many of these will fail and the shaft will need replacement OR we can repair the shaft in-situ, saving the cost of a replacement.

Shaft journals with only minor damage can usually be honed or superfinished to remove the damage and provide an “as new” bearing surface.

If the damage is deeper we can machine the shaft, either to a set undersize or down to a size where all damage has been removed.

All work is carried out with the shaft in the unit.

We can repair your damaged:

  • Crankshaft Journals
  • Motor shaft Journals
  • Pump shaft Journals
  • Turbine shaft Journals (Including vertical hydro type)
  • Generator Sliprings
  • Tailshaft Journals
  • Feed Pump Journals
  • Ball Mill Journals
  • Cement Kiln Journals

We Can Repair Your Damaged Crankshaft On-Site

Nicol & Andrew have been machining and repairing Marine and Industrial crankshafts in-situ since 1950. In fact, we invented and patented an orbital machining system back then and have been improving it ever since.

You could say our current system of on-site orbital machine tools has been 70 years in the making.


Crankpin and Main Journal Repair Technicians

If you do end up with a problem with your engine it is almost a certainty that we have come across it before and have a solution to it.

Our crankpin and main journal repair technicians have to be highly trained to carry out onsite work. This training takes many years to complete and their ultimate level of skill is quite frankly amazing. It has to be this way, as there is no margin for error when machining a crankshaft on-site.

We have very capable supervisors and teams of technicians who love to get involved with refurbishment of crankshaft, crankpin and main journal bearings, on land-based sites and also onboard sea-going vessels.

We also have off-shore trained engineers who are able to travel anywhere in the world to offshore platforms.

A Bad In-Situ Repair Could Scrap a £500,000 Crankshaft
