Radial Shaft Seals - Engine Room Consumables and Spares
Radial shaft seals are elastomeric sealing elements used to retain lubricants and exclude seawater, dirt, and dust around rotating shafts. In marine engine rooms, they are commonly fitted to pumps, gearboxes, winches, electric motors, compressors, and auxiliary machinery.
ProShipWorks provides end-to-end support to source and supply Radial Shaft Seals for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Common dimensional and design references include ISO 6194 and DIN 3760. Material, temperature, pressure, and speed limits depend on the exact seal compound and manufacturer design. Individual seals are not automatically certified for every marine application. |
|---|---|
| Class Approval | Radial shaft seals are generally supplied as machinery components rather than individually class-approved items. Where required, acceptance is normally based on the approved machinery design, manufacturer documentation, and applicable requirements of DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify shaft diameter, housing bore, seal width, rotation direction, fluid compatibility, temperature, and speed before installation. Inspect the shaft for wear and corrosion, lubricate the sealing lip with compatible clean lubricant, and install squarely without damaging the lip or spring. |
|---|---|
| Maintenance Tips | Inspect for oil leakage, lip wear, hardening, cracking, or scoring during machinery overhauls. Replace seals after shaft or bearing work and investigate the cause of premature leakage, such as excessive shaft runout, pressure, misalignment, or contamination. |
| Safety Notes | Isolate, depressurize, drain, and cool equipment before replacement. Use approved tools and avoid prying against precision shafts or housings. Confirm compatibility with fuel, lubricating oil, hydraulic fluid, and cleaning chemicals, and follow the manufacturer's speed and temperature limits. |
