I need to replace an existing ballscrew coupler to match the motors. I need help identifying the coupler source. Please have a look at the attached photo.
The coupler-ballscrew assembly is new. The coupler's overall length is 34.7mm and its diameter is 30mm. The coupler breaks down into two aluminum coupling hubs and a red plastic spider. The coupling hubs have 3/8" bore with two "teeth" each, and the spider has four "teeth" with RJS30 embossed one one.
I'd like to stick with the same make of coupler because one coupling hub is modified to also serve as a nut. The overall length of the assembled coupler is 34.7mm. Ideally, I would only need to replace one coupling hub with one from the same line with 8mm bore, per coupler.
Any help would be greatly appreciated. In the meantime, I'll keep Googling.
Thank you
