Coupling description BoWex® Curved-tooth gear couplings® are flexible shaft connections   for a positive torque transmission and specifically suitable to   compensate for axial, radial and angular shaft misalignment. According to the well-known effect of curved-tooth gear couplings any   edge pressure in the spline in case of angular and radial displacements   is avoided so that BoWex couplings are almost free from wear.
General descriptionThe mating materials polyamide/steel allows for maintenance-free continuous operation with very low friction on the teeth.
Behavior of friction and wearThe 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. While any   metallic materials tend to "corrode" in case of dry running, slide   combinations with polyamide and steel are operative without any   lubrication and maintenance.
