Wärtsilä high friction couplings and hydraulic equipment

Wärtsilä's hydraulic equipment includes a range of high friction couplings, propeller nuts and shaft flange bolts. Wärtsilä High Friction Couplings provide a shaft connection method to ship operators. Wärtsilä has engineered a specialised design approach which has enabled an increase in friction coefficient, which increases the torque transmission capacity. This can produce substantial cost savings. Through this technology, customers can avoid the use of costly reinforcement sleeves and large connection couplings can be substituted for more compact solutions. Wärtsilä hydraulic nuts are designed for heavy equipment installation. Manufactured from high quality materials, the nuts are designed to use as both an installation tool and as 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. Wärtsilä hydraulic bolts are designed to ensure the connection of flanges while still being able to meet the requirements of high torque transmission.
