Water-lubricated running
Designed specifically for submerged and splash-zone service.
ACM L2 Marine
Built for harsh marine duty
- ACM L2 Marine is a high-performance composite for water-lubricated plain bearings and sleeve bushes. The material’s fibre-reinforced structure and low-swelling resin system deliver stable clearances, low wear and dependable running in submerged or splash-zone service.It’s a proven choice for rudder stocks, pintles, fairleads, stern gear, weir gates and hydro-mechanical equipment—where downtime is not an option.
Why choose ACM L2 Marine?
Performance that stands up to seawater and silt.
Low wear, low swelling
Stable clearances and long service life in wet conditions.
High load capability
Reinforced structure handles demanding bearing pressures.
Corrosion-free
Composite construction resists galvanic corrosion and pitting.
Good shaft kindness
Polished liner surface that helps protect mating hardware.
Easy to machine & install
Readily turned, bored and grooved with standard tooling.
Typical Applications
Common bearing duties in marine and hydraulic equipment.

FAQs
Is ACM L2 Marine suitable for fully submerged bearings?
Yes—ACM L2 Marine is designed for water-lubricated operation in submerged and splash-zone conditions. Correct clearances, surface finish and grooving help establish a hydrodynamic film.
What shaft finishes work best?
Fine-ground/polished stainless or suitably coated steels perform well. Follow the datasheet for recommended hardness and Ra.
Can you machine grooves and supply finished bushes?
Absolutely. We can machine, groove and finish-size bushes to drawing and provide full traceability when required.
