48 FLE-PA

KTR BoWex 48 FLE-PA Coupling

KTR BoWex 48 FLE-PA Coupling – Original KTR Torsionally Stiff Flange Coupling

The KTR BoWex 48 FLE-PA from KTR-Kupplungstechnik is one of the most widely used torsionally stiff curved-tooth flange couplings for small to mid-size engines. Designed for connecting diesel engines to hydraulic pumps, generators, and auxiliary drives, it is part of KTR’s proven FLE-PA series. Every genuine element is manufactured in D-4440 Rheine, Germany and carries the OEM identifiers KTR, BoWex, FLE-PA, >PA6-GF25<.

Technical Data (Catalogue Reference):

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

Key Features & Advantages:

  • Compact torsionally stiff design – ensures reliable torque transfer for small and mid-size diesel drives.
  • OEM cooperation – special versions of the BoWex® 48 were developed together with engine manufacturers like Perkins and Hatz, covering a significant part of the engine-to-pump coupling market in construction and agricultural machinery.
  • Installation flexibility – wide range of SAE sizes and custom versions available to match different engine flywheels.
  • Durability – maintenance-free material combination guarantees long service life.
  • Proven OEM quality – ensures correct stiffness, alignment, and safety under dynamic loads.
⚠️ Non-original couplings may save a small upfront cost, but they cannot match the engineering precision and OEM cooperation that KTR provides. For equipment where reliability is critical — from Perkins-powered construction machines to Hatz-driven hydraulic units — only original KTR BoWex couplings deliver the performance expected by engine manufacturers.
