I connected a 1000 rpm 12V motor to a metal rod serving as an axle. They have a tight fit and don’t seem to slip. Something I didn’t expect, but that won’t hurt nor benefit my project, is these shafts are coiled in a way that they bend. I can see how this is useful for mild suspension or for printers, however one should know that these shafts bend before getting them, as for me, it was not obvious when I purchased them. The bend is about 10-15 degrees in each direction, and once pressure is relieved, it returns to a straight orientation. Gravity alone is not enough to bend these, but say they were used on a robot that weighed more than 7 pounds, I’m sure they would bend at the full 10-15 degrees, this depressing the base of the robot. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Must have CNC supply. *by B***. on Reviewed in the United States on November 4, 2022* These are a MUST have for your CNC or Laser. Should one break, your machine is down for the next few days, period. So is your cash flow. Spend a few extra and have them handy.Perfect fit for me. Be sure of the shaft sizes when ordering. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works! *by I***Y on Reviewed in the United States on September 17, 2020* These 6x6.35mm flex couplings are working well for my application.I am using them between a motor shaft and an encoder.The motor is running up to 1000 RPM and the coupling is keeping up without an issue.I can definitely recommend them. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/131887288-ranit-5pcs-4mm-to-5mm-shaft-coupling-flexible-coupler-motor](https://www.desertcart.com.ar/products/131887288-ranit-5pcs-4mm-to-5mm-shaft-coupling-flexible-coupler-motor) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
