Challenge: Large rotating equipment (such as propulsion shafts and gearboxes) requires secure, vibration-resistant bolting to maintain alignment and prevent wear. Traditional bolting methods can be labor-intensive and prone to uneven preload, leading to premature bearing failure.

Solution: Superbolt EzFit expansion bolts eliminate rotary slip between coupling halves – essential to maintain balance and alignment. This solution provides precise, uniform preload across bearing housings, ensuring secure alignment. Their multi-jackbolt design allows for easy installation and maintenance without the need for heavy torque tools, ideal for confined engine room environments. This reduces the risk of vibration-induced loosening and improves bearing longevity.

Challenge: Steering gear systems are subject to dynamic loads and shock forces during maneuvering and sea state changes. Bolted joints must maintain structural integrity and alignment to ensure responsive and reliable steering.

Solution: Boltight hydraulic tensioners enable fast, simultaneous tensioning of steering gear foundation bolts, ensuring consistent preload and minimizing stress concentrations. This improves structural stability and reduces the risk of misalignment or fatigue cracking. The system also supports rapid maintenance, reducing downtime during inspections or component replacement.
