Compressor Connecting Rods - Auxiliary Machinery and Engine Room
A compressor connecting rod transmits reciprocating force between the crankshaft and piston or crosshead in marine air compressors. It is a precision-loaded component used mainly in starting-air, service-air and control-air compressor assemblies.
ProShipWorks provides end-to-end support to source and supply Compressor Connecting Rods 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 | Connecting rods should conform to the compressor OEM drawing, material specification and dimensional tolerances. EN 10204 material certification may be required by the purchaser or class. Complete compressor performance may be tested according to ISO 1217 where applicable. |
|---|---|
| Class Approval | Approval normally applies to the complete compressor or starting-air installation rather than the connecting rod alone. Replacement parts may require OEM documentation and acceptance by DNV, ABS, Lloyd's Register, Bureau Veritas or ClassNK when fitted to classed machinery. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify compressor model, serial number and OEM part number. Check crankpin, piston-pin or crosshead-pin clearances, bearing-shell orientation, lubrication passages and rod alignment. Tighten big-end fasteners to the OEM torque and locking procedure. |
|---|---|
| Maintenance Tips | Inspect for cracks, bending, fretting, ovality and bearing wear during overhaul. Measure bore and journal clearances against OEM limits, confirm oil passages are clear, and replace bolts, bushes or bearing shells when specified. |
| Safety Notes | Isolate electrical power, vent compressed air and verify zero pressure before dismantling. Support moving components, use calibrated torque tools, and never reuse damaged or stretched connecting-rod bolts. Incorrect assembly can cause catastrophic compressor failure. |
