BELIUM BBHN series hydraulic nuts are designed and manufactured for inspection and regular maintenance and need to open the flange connection. Unlike traditional hydraulic bolt tensioners, the BELIUM HTW series hydraulic nuts are designed to permanently replace the flange with a standard hex nut. Once the hydraulic tensile force is applied to the bolt, the hydraulic tensile force is permanently preserved by the built-in mechanical load ring of the hydraulic nut

Standard series hydraulic nut, the bolt size from M22 to M100, other sizes can be customized. Hydraulic nut working pressure is 1500Bar, with quick connector, suitable for use with BELIUM manual or pneumatic or electric hydraulic bolt tensioner pump.

Typical application:

Under various conditions, high load strong vibration of the mechanical precision and reliable fastening.
