Use care when mounting the coupler, and avoid putting too much of the shaft into the coupler; only seat the shaft to the point at which the internal sizing of the coupler switches from 5mm to 8mm (the top of the narrowest part of the internal opening). If you insert the stepper motor too far, you will NOT get the full benefit of the flexible coupling!Good part at a very good price. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars They add spring to my...shaft *by D***D on Reviewed in the United States on November 24, 2021* Flexible couplings. What can one man say about flexible couplings. What generous words does the English language offer to show respect and humility towards the mighty flexible couplings? Some would say, "they work as expected." ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Work great *by V***1 on Reviewed in the United States on March 24, 2021* Works great I would suggest getting a couple 6mm ball bearings to put between the stepper and the lead scew to prevent compression --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/68408611-eewolf-2pcs-coupler-flexible-couplings-5mm-to-8mm-nema-17](https://www.desertcart.pl/products/68408611-eewolf-2pcs-coupler-flexible-couplings-5mm-to-8mm-nema-17) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-26*
