Hard-chrome piston rods, honed cylinder barrels, and seal kits from proven suppliers. Complete hydraulic power units (HPU) with directional valves, filters, and reservoirs.
Bearings & Stern Tube Components ISO 281 IACS UR W24
White metal (Babbitt) and composite stern tube bearings, intermediate shaft bearings, and thrust bearings. Shaft seals (lip seal and face seal types) compatible with major OEM brands. All bearings machined to survey measurements with class-society material certificates.
Mechanical Seals & Packing API 682 DIN 24960
Single and double mechanical seals for centrifugal pumps (John Crane, Burgmann compatible). SiC/SiC, carbon/SiC, and TC/TC face combinations. Gland packing in PTFE, graphite, and aramid fiber for valve stems and pump shafts.
Chains, Couplings & Transmission ISO 606 DIN 8187
Roller chains, anchor chains (Grade U2/U3), flexible couplings (Vulkan-compatible), and cardan shafts. Brake linings and pads for winch and crane brake systems.
Parts Sourcing Quality Process
Every replacement part is verified against OEM specifications before shipment.
OEM Cross-Reference
Match your part number or drawing to our approved manufacturer database. Confirm dimensions, materials, and tolerances against OEM specifications.
Manufacturing
CNC machining, grinding, and surface treatment to OEM tolerances (typically ±0.01mm for bearing surfaces). Material certificates for all wetted and load-bearing parts.
Dimensional Inspection
100% dimensional check against drawing. CMM measurement reports for precision components. Hardness and surface-roughness testing where specified.
Packing & Documentation
Anti-corrosion treatment, VCI wrapping for precision surfaces. Each part labelled with part number and drawing reference. Inspection reports and material certificates included.
