Through the manufacture of high-quality ship components suitable for the global marine environment and customized on-site maintenance services, we are growing into a trusted partner in the domestic and international shipbuilding and shipping markets.

Business Areas

Manufacturing of Sterntube Seal Components for Ships: We manufacture and supply key components such as Seal Rings, Liners, and Spacer Rings, which prevent lubricant leakage from the ship's propeller shaft and block seawater ingress.

Sterntube Seal Maintenance and Replacement Services: We provide vulcanizing joint maintenance services that allow for the replacement of seal rings without removing the propeller or shaft while the vessel is in dry dock or moored at sea.

Main Products

ABR-2 New Material Seal Ring: This is a high-performance seal ring that applies surface-modified hybrid Viton material, offering low wear resistance, long lifespan, and compatibility with environmentally acceptable lubricants (EAL).

High-Chrome Steel Liner: This is a precisely machined ship liner product made from high-chrome steel, which is resistant to corrosion and wear.

Spacer Ring: This component extends the lifespan of the liner by readjusting the operating position of the seal ring to avoid worn areas of the liner.

Strengths

Proprietary New Material Technology: We possess ABR-2 new material technology that significantly improves hardness, wear resistance, and flexibility compared to existing rubber materials through nano-material blending technology.

Major Classification Society Certifications and Global Standard Compliance: We have obtained Type Approval from major international classification societies, proving our quality and stability in the global market.

Efficient Non-Removal Vulcanizing Maintenance Technology: Our advanced vulcanizing joint technology allows for direct seal replacement on-site without disassembling the propeller or shaft, significantly saving time and cost for shipowners.

Job Posting Analysis

Main Recruitment Positions: Ship component manufacturing and precision processing, Field maintenance engineer (A/S technical support), Production management

Average Annual Salary Level: Average annual salary approximately 30 million KRW or more ~ less than 50 million KRW
