SinoShaft offers expert seal services for marine propulsion systems, ensuring vessels operate at peak performance while adhering to environmental standards. Our comprehensive seal services include stern tube seal bonding, replacement, and overhaul services for a wide range of ship types and sizes.

One of our projects involved the stern tube seal bonding for the container vessel “EVER GRADE” at Zhoushan Xinya Shipyard. This service involved the application of the Wartsila 4AS 1180 stern tube seal, ensuring the vessel maintained maximum operational reliability while minimizing downtime during drydocking.

SinoShaft’s sealing solutions are engineered to withstand the harsh marine environment, offering long-term protection against wear, corrosion, and leakage. Our seals are fully compatible with Environmentally Acceptable Lubricants (EALs), ensuring compliance with both current environmental and Vessel General Permit (VGP) requirements.

SinoShaft Marine Technology Co., Ltd. has long been known for its expertise in marine propulsion system maintenance and stern tube seal services. We are now focused on expanding our capabilities to include advanced Energy Saving Devices (ESDs) and Shaft Generator Systems.
