It sounds like something I could make, but I can't be sure or give a price without first seeing a drawing
Thanks Jonathon, its basically the bearing side of the revolving ballnut design. I'm working on a drawing, but I'm not very good with the 3d stuff at the moment... Its really just an aluminium block approx 110 x 110 x 60 with an 80mm bore either side to take 2 angular contact bearings. Oh, and I need 2 of them please...
