    The next generation
    coupling bolt.

HYCOBOLT hydraulic coupling bolts

HYCOBOLT is the most advanced hydraulic coupling bolt, delivering high performance torque transmission for critical high load rotating shafts and couplings. It is a direct retrofit replacement or alternative to a conventional coupling bolt, providing significant benefits through both operational improvements in coupling performance and time saving during plant maintenance periods.

The benefits of the HYCOBOLT can be fully exploited when used in high value capital equipment where demanding performance requirements and maximising availability are a priority. Hydraulic coupling bolt technology is an established solution for the power generation industry and is supported by major OEMs. The HYCOBOLT can be used in all types of equipment from conventional steam to high efficiency gas turbines, hydro and wind turbines as well as large electric motor drives, marine propulsion shaft lines and heavy rotating machinery.

The innovative HYCOBOLT design overcomes the problems of conventional and previous generation coupling bolts with a fast and reliable installation and removal process. It is your next generation alternative to conventional fitted bolts on rotating machinery. Simple, safe and reliable, it's designed to reduce vibration and eliminate coupling slippage, ensuring a significant return on capital investment through time saving, predictable and controlled workflow scheduling and maximisation of plant availability.
