These Flexible couplings are used to transmit torque from a stepper motor to a lead screw, thus creating the movement in an actuator.
- Adds approximately 5% flexibility to help with misalignment
- Independent screw to lock shafts
- Can reduce vibration

I wanted to say thank you for the BEST 5 to 8mm flex coupling I have found and used to date. I used this coupling to replace the original Creality ones on all my Ender 3 and 5 printers. In addition I used these to replace the flex coupling that use just the set screws. Because of the closer bore tolerances for the 5 & 8 mm openings and because this coupling uses a clam shell style clamp that will not miss align the lead screw or the stepper motor shaft. This coupling functions perfectly with a T8 - Tr8x2 leadscrew. This set up allows for even step per 0.2 layer settings without using micro-stepping for a near perfect wall layer. This coupling has a great price as well. To date there is not a better one that I have found. My makers thought. Thanks again Doc'
I purchased this for a DIY CNC project machine. It arrived faster then anticipated and the packaging was very nicely done. I haven't used the product yet but close inspection gives away that it surpasses similar products via. Amazon. This is one of many I need.
I wanted to replace the stock couplers on my CR10s, these were recommended on a vlog I watch as being good quality. I'm very happy with them. They're more flexible that the stock ones and they are beautifully machined. Happy with my purchase.
Needed an 8mm to 8mm coupler but was not able to grt one quickly. Got this one and drilled out the smaller side. Works great
