BoWex FLE-PA Couplings with 50 Teeth – Size BoWex 48 FLE-PA

The BoWex® 48 FLE-PA is the torsionally stiff flange coupling from KTR-Kupplungstechnik that comes with 50 inner teeth. Teeth count is directly related to the flange size, and in this case, the 50 teeth design corresponds to size 48.
This coupling is widely used in small and medium diesel engines for driving pumps, generators, and hydraulic systems in construction and agricultural machinery. Developed together with OEMs such as Perkins and Hatz, the BoWex 48 FLE-PA ensures full compatibility with engine flywheels and pump mounting flanges.

Key Specifications:

  • Inner teeth count: 50 teeth
  • Nominal torque (TKN): 240 Nm
  • Maximum torque (TKmax): 600 Nm
  • Available SAE sizes: 6.5″, 7.5″, 8″, 10″
  • Design: Torsionally stiff, curved-tooth, maintenance-free
  • Material: Polyamide >PA6-GF25< with steel hub

Why teeth count matters:

The number of teeth defines the connection geometry between the engine flywheel and the coupling hub. Correct teeth count ensures proper alignment, torque transfer, and long service life. Using a coupling with the wrong teeth number risks misalignment, premature wear, or even engine damage.
⚠️ As with all couplings, only original KTR elements marked with KTR, BoWex, FLE-PA, >PA6-GF25<, D-4440 Rheine guarantee OEM precision. Non-original parts may appear similar but often lack correct stiffness and tooth geometry, leading to costly failures.
