Bolt Tensioning Cylinders

Hydraulic, friction- and torsion-free ITH Bolt Tensioning Cylinders

No friction, no torsion, no bending. The tensioning force of the cylinder is applied straight to the bolt.

Hydraulic Bolt Tensioners, or BTC's for short, are mostly designed for a specific bolt connection. This ensures an optimized connection with high usage of the mechanical properties of the fasteners as well as fast and easy usage.
