Family Overview
Elastic Pin Couplings
Elastic pin couplings use circumferential pins and elastic elements to transmit torque through a compact flexible connection. They are commonly considered for general industrial shaft connections where the final choice must coordinate torque, speed, bore and installation space.

Selection
What to confirm before choosing a series
Use the following checks to narrow the family without turning the page into one long block of text.
- Confirm torque and allowable speed on the same model row.
- Check both shaft-hole diameters and usable shaft lengths.
- Review pin and elastic-element access before the guard is finalized.
- Compare the overall envelope with adjacent bearings, guards and machine frames.
Structure & Interface
Use the drawing to verify the torque path and shaft arrangement
The structural reference is intended for understanding the family layout. Exact bore, shaft-hole length and outer dimensions remain model-specific, so the selected series page should be checked before quotation.
For replacement work, compare the existing coupling drawing with the proposed series rather than relying on a similar family name.

FAQ
Common selection questions
Can I select from torque alone?
No. Operating speed, both shaft interfaces and the installation envelope must also match the selected model.
Can a similar series name confirm interchangeability?
No. Replacement suitability requires a dimensional and interface comparison against the existing drawing or measured machine data.
What information should I send with an RFQ?
Send torque or motor data, operating speed, both shaft diameters, usable shaft lengths, driven equipment, quantity and a drawing when available.
Where are the detailed dimensions?
Open the relevant product series page. The product page keeps the main product image separate from the published technical and dimensional reference.
