Seals - Bearings, Packing and Jointing
Marine seals, bearing materials, gland packing and jointing products are used to prevent leakage, reduce friction and protect propulsion, pumps, valves and piping systems. Selection depends on shaft speed, pressure, temperature, fluid compatibility and classification requirements.
ProShipWorks provides end-to-end support to source and supply Seals for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Manufacturer data sheets define material and service limits. |
|---|---|
| Class Approval | Marine applications may require approval or acceptance from DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK or another IACS member. Approval is product-, vessel- and application-specific; not all seals, bearings or packing products are class-approved. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify dimensions, shaft condition, flange rating, material compatibility and operating limits before installation. Clean mating surfaces, use correct compression or gland adjustment, and follow the manufacturer's installation instructions. Do not reuse damaged gaskets or seals. |
|---|---|
| Maintenance Tips | Inspect for leakage, wear, overheating, abnormal vibration and loss of compression. Check gland packing adjustment and monitor bearing clearances where applicable. Replace seals, packing and jointing materials at recommended overhaul intervals or when deterioration is found. |
| Safety Notes | Isolate, depressurize, drain and cool equipment before replacement. Use appropriate personal protective equipment and follow confined-space, lockout/tagout and hot-work procedures. Confirm chemical compatibility and never exceed the product's rated pressure, temperature or speed. |
