HydraSure Nuts are a modern, safe and efficient way to precise tool clamping.
HydraSure Nuts replace conventional torque-loaded threaded nuts to make shaft tensioning a simple, efficient and safe hydraulically assisted operation.
They are manufactured in a wide range of sizes and materials to suit applications throughout many industries.
AR Model HydraSure Nuts are made in a standard range to suit thread sizes from 50mm to 300mm and other sizes by request.
How do they work?
The HydraSure is screwed onto the shaft. The quick connect coupling allows pressure to be supplied by a hydraulic pump. A calculated hydraulic force applied to a known piston area results in a precise load being applied to the shaft. The shaft is stretched and the lockring is then wound down to retain the load.
The hydraulic pressure is released and the hose is disconnected. HydraSure takes only minutes to tension any size of bolt.
In addition, Technofast Industries offer a specialist shaft manufacturing service to heavy industry. Typical uses include pipe rolling mills, crusher components and driveline equipment.
All shafts are produced in Technofast Industries’ Brisbane manufacturing facility which is ISO 9001: 2000 Certified.
Technofast Industries offers engineering and design support for any application. Technofast utilise computer-based manufacturing and engineering analysis.
