The HyGrip connection coupling consists of a twin-walled pressure sleeve. It is pressurized with oil up to 1 000 bar and sealed with a brass valve. This results in a completely backlash-free frictional connection. HyGrip connection couplings can be specifically designed to meet the exact requirements of the application. The torque transmission capacity and the axial forces are proportional to the oil pressure. The connection can be set and released very quickly if a suitable hydraulic pump is used. HyGrip couplings have limited radial force capacity.
Typical industrial applications are, for example, fixing of straightening and cutting rolls where the radial forces are low, or fixing of flexible drive shafts and couplings for easy assembly and disassembly.
