Introduction:

Flexible Coupling Sets - Connects a single motor to a lead screw end (Two Hubs and One Middle Spider)

Description:

We have an assortment of bores (shaft diameters) from which to choose. How to choose, the first measurement is one side and the second measurement is the opposite side, pretty simple. Say you have a 1/4" motor shaft, and the lead screw is 5/8", you will need a 1/4" to 5/8" coupling. Each coupling comes in three parts, two hubs and one insert.

[Flexible Coupling Sets - Connects a single motor to a lead screw end (Two Hubs and One Middle Spider)] Is there extra backlash with these installed?

Yes, there is backlash with flexible couplings. The backlash exists between the spaces of the buna spider and the hub connection. The fit is tight, but there is a bit of backlash, and over time, the buna spider can change in dimension, causing more backlash. These couplings are best used on leadscrew with a tight pitch.
