BBHN Series Hydraulic Nuts

Max. Pressure: 100 MPa Stroke: 5-30 mm

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.
