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 | Rolling-element bearing selection commonly references ISO 281 for rating life and ISO 76 for static load rating. Plain-bearing design may reference ISO 4378. Packing and gasket materials should comply with the applicable manufacturer, piping, temperature, pressure and fluid-service requirements. |
|---|---|
| Class Approval | Classification requirements depend on the machinery and vessel application. DNV, ABS, Lloyd's Register, Bureau Veritas and ClassNK may require approved or type-approved thrust-bearing arrangements for propulsion and essential machinery. Approval is manufacturer- and application-specific. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify bearing type, dimensions, load rating, shaft alignment, lubrication and clearances against the maker's drawing. Install thrust pads or rolling elements in the specified orientation. Fit packing and jointing materials on clean, undamaged sealing surfaces using the specified compression and bolt-tightening sequence. |
|---|---|
| Maintenance Tips | Monitor oil pressure, temperature, vibration, axial movement and bearing wear. Inspect thrust pads, races, lubrication passages and shaft surfaces during planned overhauls. Renew packing and gaskets when leakage, hardening, compression set or damage is found; do not reuse compressed gaskets unless specifically permitted. |
| Safety Notes | Isolate, lock out and depressurize machinery before work. Prevent shaft rotation during installation. Use the specified lubricant and sealing material, observe hot-surface and chemical hazards, and follow class, maker and vessel safety procedures. |
