Nylon couplings are compact and can operate over a wide temperature range at speeds up to 5,000 RPM and are effectively used in applications such as Motor/ Generator sets, pump sets, and many lightAtoAmedium duty industrial coupling applications. The resilient nature of the nylon material makes the contact of the hubs and sleeves almost frictionless. Since no lubrication is used, the coupling can readily be adapted to many applications including vertical and blind installations where the slipA together components offer easy inspection and adjustment. The smooth and hard surface (crystalline structure) and the high thermal stability and resistance to lubricants, fuels, hydraulic fluids, dissolvents etc. make polyamide an ideal material for components stressed by sliding, particularly for the coupling production.
