Shaft couplings, propeller nuts and shaft flange bolts designed for easy handling and trouble free operation
Wärtsilä hydraulic equipment includes varieties of shaft couplings, propeller nuts and shaft flange bolts.
Hydraulic couplings provide a simple and quick way to connect shafts, eliminating the need for keyways, tapers or thrust rings.
The hydraulic shaft coupling range consists of four design types: OHSM, OHSM-B and OHSM-V are flange couplings and connect a shaft to a gearbox, engine or another shaft. OHSN couplings are designed to connect two standard shafts.
Commercial oil lubricated hydraulic shaft couplings
Commercial oil lubricated hydraulic nuts
Wärtsilä hydraulic nuts are for heavy equipment installation. Manufactured from high quality materials, the nuts are designed for use as both an installation tool and a permanent nut. The fitting process is controlled by means of a hydraulic procedure. The process is clean, quick and trouble free with the simple use of one set of hydraulic equipment.
Commercial oil lubricated hydraulic bolts
Wärtsilä hydraulic bolts are designed to ensure the easy connection of flanges while still being able to meet the requirements of high torque transmission.
The high quality bolts keep the connections rigid under extreme operating condition. They are easy to install and remove as well as reusable.
