Superbolt Component
Superbolt HyFit
Hydraulically actuated, truly fitted expanding coupling bolt system for steam and gas turbines, marine propulsion drives and heavy rotating equipment.
Description
Superbolt HyFit is a hydraulically actuated, truly fitted expanding coupling bolt that is installed and removed in clearance condition, preventing the coupling slippage and hole and bolt damage associated with traditional fitted bolts. It is a system engineered for each requirement rather than a standard range, and incorporates a Boltight hydraulic bolt tensioner and hydraulic nut.
Key features
- Two dimensionally different heads and one operating pressure, eliminating wrong-pressure risk
- Removes the need for oil-injection removal methods
- HyFit nut can be retrofitted to existing coupling bolts
- Less demanding hole tolerances; split sleeves allow greater expansion
- Fully reusable; only sleeve replacement needed for rotor changes
Applications
- Marine propulsion drives
- Steam and gas turbines
- Heavy rotating equipment
