ACM Bearing is a high-performance composite material made by layering a compound of specialty polyester resin, precision fibers, and additives.
This advanced composite dramatically improves physical and chemical properties, offering high load capacity, a low coefficient of friction, and excellent chemical resistance — all while being lighter and more economical than metal. Certified to ISO 9001:2015 and approved by five major classification societies (KR, DNV, ABS, BV, CCS), it is widely used in ships, bridges, nuclear/thermal power plants, pumps, automotive, and construction equipment.
Static compressive strength up to 375 N/mm² and dynamic strength of 100 N/mm² make it a proven replacement for bronze bushings.
A dry friction coefficient of 0.13–0.15 enables oil-free operation.
Minimal heat transfer preserves hardness, delivering excellent wear resistance.
Water absorption below 0.15% ensures high dimensional stability and precision tolerances.
A low coefficient of thermal expansion allows precision-tolerance designs that reduce shaft vibration.
Performs reliably under dry, grease, oil, and submerged lubrication conditions alike.
Charpy impact strength of 100 kJ/m² combined with excellent corrosion resistance for environmentally friendly operation.
Low-vibration, low-noise operation with responsive inventory support and rapid custom manufacturing.
