- Flange typically sized for SAE 18 or custom large-diameter flywheels
- Made from glass fiber-reinforced polyamide (PA6-GF25)
- Torsionally rigid, dry-running design – no lubrication required
- Withstands angular and axial misalignment under load
- Ideal for mining equipment, marine auxiliaries, large powerpacks, and stationary pumps or compressors
🧩 Field Identification:
When replacing a damaged or aged flange, look for:
- Printed marking: BoWex® 125 FLE-PA
- Manufacturer: KTR-Kupplungstechnik
- Material code: >PA6-GF25<
- Location: D-4440 Rheine
- Internal tooth count: 54 teeth
If the marking is missing, count the internal teeth and measure the flange diameter or bolt pattern. You can also check the matching spline hub for identification.
