Plastic Bush
Plastic Bush featuring a specialized internal drive profile (tri-lobe / keyed bore) and flanged collar is manufactured by Active Polymers for precision shaft couplings, motor drive linkages, and mechanical alignment assemblies. Engineered from high-tensile, dimensionally stable polymers, it prevents rotational slippage on keyed shafts while accommodating smooth axial movement and dampening torsional vibrations. It represents a lightweight, non-corrosive, and maintenance-free replacement for traditional sintered bronze or steel bushings in demanding applications.
