Goltens has long been the leader in In-Situ crankshaft and journal grinding and machining. As the first company in the world to complete In-Situ crankshaft grinding in the early 1950s, Goltens’ patents on its In-Situ crankshaft grinding tooling revolutionized the industry with massive reductions in down time for owners coping with crankshaft failure and damaged journals.

Through constant and focused R&D and field trial, Goltens has developed the most cutting edge crankshaft/journal machining tooling in the industry. On larger diesel engines and damaged journals, this allows our highly skilled technicians to perform large scale jobs in a fraction of the time of traditional grinding, oftentimes with a single cut fillet to fillet with the highest tolerances.

Goltens’ experience repairing damaged crankshafts extends far beyond the grinding and cutting of crankshafts. Goltens has a great deal of experience repairing bent and twisted crankshafts In-Situ as well as the expert use of annealing In-Situ to remove hardness from otherwise condemned crankshafts.

Goltens’ brand has always been synonymous with the repair of diesel crankshafts however, every year Goltens applies this technology to problems in the marine, industrial, stationary power and offshore sectors. Goltens is routinely called upon to repair damaged journals on any and all manner of rotating equipment including compressors, turbines and other shafts and journals.
