ACM Composite

What ACM Composite does

ACM Composite Bearings (legal name ACM Composites) is a UK-based manufacturer of engineered synthetic composite bearing materials, headquartered in Rotherham, South Yorkshire. The company designs and supplies precision plain and spherical bearings intended for harsh operating conditions, with a portfolio of nine proprietary composite material grades spanning marine/submerged service (ACM L2 Marine), dry and boundary-lubricated duty (TriboTex 3 and 7), elevated temperatures (TriboTemp 10 and 20), high-load and impact resistance (TriboTough 10), chemical resistance (TriboChem 11), low-friction dry running (TriboGlide 15), and sliding applications (TriboSlide). Supporting services include design and engineering support, machining and finishing, testing and inspection, and certificates with batch traceability.

ACM serves eight industrial verticals: Marine, Offshore, Hydropower, Inshore, Fluid Power, Construction, Machinery & Processing, and Rail & Trackside. Its customers are manufacturers and maintenance teams, predominantly in the UK and Europe, with theoretical global reach via its parent HEF Group, a conglomerate operating in 21 countries with expertise in tribology, photonics, and hydrogen technologies.

Revenue is generated primarily through hardware sales of standard bearings from UK stock (with same-day despatch options) and custom machined parts, supplemented by technical service revenue covering design guidance, machining, testing, and traceability documentation. The go-to-market is sales-led and direct, with quote-based pricing, engineer-led technical advisory, and flexible supply arrangements ranging from one-off parts to scheduled Kanban deliveries. The company operates as a subsidiary of HEF Group, leveraging the parent's R&D capabilities while maintaining operational focus on UK and European customers.
