🧩 Field Identification Support

Many breakdown cases involve worn or unmarked couplings. Common visible markings include:

BoWex® XX FLE-PA | KTR-Kupplungstechnik | >PA6-GF25< | D-4440 Rheine

To identify the correct part, check:

• Flange diameter (SAE-based, e.g., 314.25 mm)
• Internal tooth count (e.g., 48 FLE-PA = 50 teeth, 65 FLE-PA = 42 teeth, 80 FLE-PA = 46 teeth, 100 FLE-PA = 48 teeth)
• Bolt pattern and flange thickness
• Or simply send us a photo and we’ll verify it for you.
