Approved by leading classification societies

Connecting rigid shafts with OK couplings is a timesaving solution that has been used on land and at sea for more than fifty years. The couplings are well known all over the world for their high quality, creative design and operational safety.
In the production line each step is carefully controlled and the finished couplings are subjected to a rigid final inspection regarding sizes and steel quality before delivery. The couplings are also approved by all major classification societies, for example Det Norske Veritas.
