Couple your shafts or lead screws with this one piece 1/2" (12.7mm) to 1/4" (6.35mm) flexible clamping coupling. These flexible couplings will allow a bit of misalignment. 1/2" to 1/4" - one piece flexible clamping coupling (also called coupler). Typical flexible couplings will contain two hubs and a rubber spider in the middle. This coupling is a one piece coupling so there is no need to stabilize the lead screw, or shaft since this coupling will maintain its structure. There are two bores in this coupler so a 1/4" motor shaft can be coupled to a 1/2" shaft or lead screw. The outside diameter is 1" (25.4mm). The length of the coupler is 1.19 inches (30mm).
