BoWex® FLE-PA Couplings with 48 Teeth – KTR BoWex 100 FLE-PA
The BoWex® 100 FLE-PA from KTR-Kupplungstechnik is a torsionally stiff curved-tooth flange coupling designed with 48 inner teeth. In the KTR portfolio, the teeth number directly defines the flange geometry, and the 48 teeth configuration corresponds to size 100.
This coupling is typically used in marine engines, generator sets, and heavy-duty construction equipment, where high torque transmission and durability are essential. Manufactured in D-4440 Rheine, Germany, each original element is marked with KTR, BoWex, FLE-PA, >PA6-GF25<, certifying OEM quality and authenticity.

Why teeth count matters:
The 48 teeth profile ensures precise engagement with the flywheel, delivering secure torque transfer and proper alignment. Using the correct teeth geometry is critical for minimizing wear, preventing vibration, and extending service life of both the coupling and the drive train.
⚠️ Non-original couplings may look similar but often lack the exact teeth geometry and stiffness required. While they may offer small short-term savings, the risks of misalignment, premature failure, or costly downtime make them unsuitable for high-value machinery. Only original KTR BoWex couplings guarantee full performance and reliability.
