Product features

  • Torsionally rigid curved-tooth flange coupling

  • Applicable to all hydrostatic drives, e. g. construction machines and harvesting machines

  • High torsion spring stiffness, resonance-free operation

  • Maintenance-free due to material combination nylon/steel

  • PA flange with high mechanical strength and heat stability

  • Special connection flanges available

  • Torques from 240 to 5,300 Nm"

Mobile machines mainly use I.C.-engines as a drive. On hydrostatic drives hydraulic pumps are directly connected, while the compressor unit is driven directly with mobile compressors. Both units are connected via a flange coupling. That is why it has to meet a large number of demands, while primarily it has to transmit the power reliably to ensure that the machine is in a position to perform the work as required.

BoWex® FLE-PA (General description)

The mating materials polyamide/steel allows for maintenance-free continuous operation with very low friction on the teeth.

BoWex® Flange couplings - Behaviour of friction and wear

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.

Pump mounting flanges

Pump mounting flanges

For connecting hydraulic pumps to the diesel engine KTR supplies mounting flanges according to SAE connection dimensions sizes SAE 6 to SAE 1. These flanges are made of steel and EN-GJL--250 (GG25) for hydraulic pumps with flange connections according to SAE-A, -B, -C, -D and -E as types with 2 and 4 holes.

Pump connection housings made of EN-GJL-250 (GG25) to be mounted directly to the back plate of the engine.
