About this item
- Connection Diameter: 1/4 inch to 10mm, Total Length: 25mm /0.98 inch, Outside Diameter : 16mm/ 0.63 inch
- Widely used in blowers,3D printer,DIY robots,CNC machine,stepper motors,etc. Similar to rigid clamp couplings, shaft couplers are used to hold bearings and sprockets tightly on the shaft, and are used in motor and gearbox assemblies.
- Top tight type rigid coupling with 2/4 screws to hold the shaft tightly; high torque with rigidity, low inertia and excellent sensitivity.
- NOTE: The rigid type basically does not allow eccentricity, and it must be fully adjusted during use.
- Single piece set screw clamp design makes it easy to set up the items on the shaft and control the holding capacity of the coupling.

Customers are satisfied with the tightness of the nuts. They mention that the machining ensures the rigid coupling grips their shaft completely, and the stainless steel composition holds nice and tight.

Customers are mixed about the fit. Some mention that the nuts hold nice and tight, while others say that the sizing is off, sloppy, and the rod would not fit. The 5mm side was slightly under dimension and the set screws do not stay tight.

Customers are mixed about the screws. Some mention that the set screws are just big enough to barely bite into the shafts, and the extra set screws work well to hold it into place. However, others say that they arrived without set screws, are rather thin so there are not many threads to hold the screw in place, and that the screws come loose.
"...the set screws go through are rather thin so there are not many threads to hold the screw in place. This is especially true for the 8mm hole side...." Read more

"...However the bolts kept loosening and that let the stepper motors spin without moving the ball screws...." Read more
"Was well made and glad it came with the 90 degree set screws. I used this on a focuser project for my telescope...." Read more

There was a problem filtering reviews right now. Please try again later.
I am building a linear stage which uses a 5/16" threaded rod and a 12VDC motor with a 4mm shaft. I needed to connect them together. I talked with employees at the big box hardware stores and department stores -- they had no idea what to use to make the connection. It wasn't until I realized that the motor manufacturer would probably have good ideas for how to make the connection that I found these connectors.
Worth they money
The set screws are just big enough to barely bite into the shafts. I highly recommend grinding a small flat for the set screws to anchor onto.
I am very happy with the purchase. They did the trick!
If so, this is a good option - the set screws and precision machining ensure the rigid coupling grips your shaft completely, and the stainless steel composition means you don't have to worry about lubricants or other fluids causing corrosion or discoloration of your shaft.
