Hydraulic bolt tensioner with threaded insert

Hydraulic bolt tensioner with threaded insert

The CTP series hydraulic tensioner is designed for controlled tightening of nuts on stud bolts when different thread types must be handled while keeping similar installation clearances.

Its interchangeable threaded insert configuration provides high versatility and allows the system to be adapted to the application and existing dimensions using insert sets, suitable keys and, in some cases, bridges.

Key Features

• Interchangeable threaded insert: Enables operation on studs with different threads using just one hydraulic cell.
• High versatility: Ideal whenever stud bolts with different threads and similar dimensions must be tensioned.
• Custom design: F.P.T. manufactures these hydraulic tensioners to customer specifications after a preliminary study of the existing dimensions and clearances.
• Industrial applications: Used for controlled tightening in marine engines, large ball valves, compressors, pumps, presses, large machine tools and turbines.
