BoWex® FLE-PAC torsionally stiff flange coupling

The Bowex FLE-PAC curved-tooth flange coupling is a further development of BoWex FLE-PA for the use on I. C.-engines and hydraulic pumps.

With this type the mounting flange is made of high-quality carbon fibre material resulting in excellent properties of wear and a high service life expectation of the flange coupling. Moreover, the flange coupling is featured by high mechanical component strength and heat stability.

The curved-tooth flange coupling is very flexible in design. The connection dimensions of the flange are available according to SAE standard as well as special dimensions as a one-piece design and the steel hubs of the wide standard product portfolio of BoWex shaft couplings can be combined in any design.

  • Pump mounting flanges
  • MMC coolers

The smooth and hard surface (crystalline structure) and the high thermal stability and resistance to lubricants, fuels, hydraulic liquids, dissolvents, etc. make polyamide an ideal material for components stressed by sliding, particularly for the coupling manufacture.
