Over the past 60 years, we have applied our tooling and expertise to recondition over 25,000 crankshafts worldwide, as well as countless other rotating journals and shafting.

As the first company in the world to complete in-place crankshaft grinding in the early 1950s, Goltens’ tooling patents revolutionized the industry with massive reductions in downtime for owners.

Continuous R&D and field trials have given us the best tooling for crankshaft/ journal machining in the industry. This allows us to perform large-scale jobs in a fraction of the time of traditional grinding, often with a single cut fillet to fillet with the highest tolerances. We apply our technology to challenges in the marine, industrial, stationary power and offshore sectors.

We repair damaged journals on any and all manner of rotating equipment including compressors, turbines and other shafts.

Crankshaft/ Journal Annealing

Over the past 5 years, Goltens stations around the world have successfully annealed over 75 crankshafts, saving customers tens of millions of dollars in unnecessary crankshaft purchases, major engine rebuilds, as well as countless days of lost operational capacity.

Loss of a crankshaft or any rotating shaft due to high hardness values is a costly, time consuming, and extremely disruptive occurrence. As the market leader in In-Situ crankshaft repairs, we encounter many crankshafts with areas of excessive hardness each year.

Excessive hardness can often be machined away by Goltens’ In-Situ teams, provided that there is sufficient remaining material to remain within manufacturer’s maximum allowable undersize. However, when this is not possible, the only remaining options are either to scrap the crankshaft, or remove hardness by annealing.

Over the years, we have refined our process for annealing crankshafts and other shafting, and can do this successfully in-place as well as in our workshops around the world. Our deep understanding of the metallurgy, expansion characteristics, and safety Precautions, has been developed and refined over the years, to create a safe, repeatable, highly controlled process.

We have repeatedly demonstrated that hardness can Be successfully removed and that minor finish grinding/cutting can restore the machinery to service with significantly less loss of shat diameter, as well as the avoidance of costly shaft/equipment removal, and the purchase of a replacement crankshaft.

• Goltens has undertaken extensive workshop trials with Class Society and select OEM involvement and subsequent metallurgical analysis to demonstrate the results of the process.

• Goltens has received job specific approvals for In-situ annealing of marine crankshafts from several Class Societies

Class Approval

• Comprehensive capability to handle all aspects of hardness treatment inclusive of engine preparation, inspection, pre-Machining, hardness removal and finish machining as well as

• engine reassembly • A large, global team of highly skilled In-Situ technicians to

ensure a rapid, expert response anytime and anywhere • Extensive experience successfully annealing crankshafts

across a broad array of makes and models of engines and rotating machinery

• Globally deployed and available portable annealing equipment for In-Situ application
