Ship Stern Shafts & Propeller Shafts
Our custom and mass-produced ship stern shafts and propeller shafts form the backbone of our propulsion offerings. We manufacture them with high precision to meet strict tolerances. These shafts deliver smooth propulsion performance. They also minimize vibration and mechanical wear over long voyages.
Stern Tube Bearings & Intermediate Bearings
We craft our stern tube bearings and intermediate bearings from highly durable materials. This maintains perfect alignment and reduces mechanical losses. These critical marine shaft system components ensure long-term stability. They absorb operational stresses and extend the lifespan of the entire propulsion setup.
Stern Shaft Seals & Bulkhead Transmission Devices
Protecting the internal environment of your vessel is paramount. Therefore, we engineer our stern shaft seals and bulkhead transmission devices for absolute reliability. These sealing solutions effectively prevent water ingress and oil leaks. They maintain optimal pressure and alignment even under harsh marine conditions.
Rudder Shafts & Upper/Lower Rudder Bearings
A complete propulsion setup requires equally robust steering components. Our rudder shafts, along with upper and lower rudder bearings, seamlessly complement the main shafting. This integration provides complete vessel maneuverability, ensuring safe and responsive navigation in all waters.
