FPT – Fluid Power Technology is a manufacturer of hydraulic nuts for bearings and components.
The hydraulic nuts are used for installation and removal of components such as couplings, gears and ship propellers, rudder blades, shaft blade connection or large pieces on conical seats and for assembling and disassembling bearings. The bearings can be inserted directly on a conical shaft, on an adapter sleeve or on an extraction sleeve. If the bearing is mounted using an extraction sleeve or an adapter sleeve, the hydraulic ring nut can also be used for removal. They also find application when a strong tightening torque is required, mainly used when the maneuvering spaces are limited or in the case of frequent disassembly, reassembly and assembly.
The oil is pumped into the ring nut and the piston is pushed outwards with a high force suitable for the operations to be performed. The hydraulic nuts can have various threads and dimensions and are driven by a hand pump or a high pressure hydraulic unit. Custom solutions can be produced on request, such as hydraulic nuts with special threads, metric threads, trapezoidal, in inches or special forces and push area. The hydraulic system is supplied with very high pressure hand pumps and air hydrauic pumps up to 3000 bar and the very high pressure manifold system, quick coupling and fittings.
