BoWex® FLE-PA couplings are torsionally rigid curved-tooth flange couplings consisting of the material combination nylon/steel for diesel engine drives in combination with hydraulic pumps. The FLE-PA adapter flange consists of fibre-glass reinforced polyamide having a high mechanical strength and thermal stability. The hub of the coupling having an external curved toothing is made of steel. BoWex® FLE-PA allows for an extremely short installation. Moreover, it is easy to assemble with no need for additional alignment tools.
The mating materials polyamide/steel allows for maintenance-free continuous operation with very low friction on the teeth.
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. 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.
