BoWex® FLE-PA Couplings with 46 Teeth – KTR BoWex 80 FLE-PA
The BoWex® 80 FLE-PA is an original torsionally stiff flange coupling from KTR-Kupplungstechnik, featuring 46 inner teeth. In KTR’s product range, the teeth count defines the flange geometry, and the 46 teeth version corresponds to size 80.
This coupling is widely used in diesel engine applications for connecting pumps, generators, and marine auxiliary drives. Its torsionally stiff curved-tooth design ensures accurate torque transmission and reliable alignment, even under dynamic loads. Each genuine element is produced in D-4440 Rheine, Germany, and marked with KTR, BoWex, FLE-PA, >PA6-GF25<, confirming OEM quality.

Why teeth count matters:
The 46 teeth profile provides the correct geometry for mounting to the engine flywheel. Correct teeth engagement ensures low wear, vibration-free operation, and secure torque transfer. Using the wrong tooth configuration may cause misalignment, premature wear, or damage to the coupling and drive train.
⚠️ While non-original couplings may appear cheaper, they often lack correct teeth geometry and stiffness. For high-value machinery — whether in marine propulsion, generator sets, or construction equipment — the risks far outweigh the small savings. Only original KTR BoWex couplings guarantee precision fit and long-term reliability.
