The rails I bought were the size to match the size of machine I could fit in my garage, don't know what motors, drivers etc, etc I'll need

this is what I purchased from, yes you are right - linearmotionbearings

linear rails SBR16-300/600/700mm rails(6 supported rails+12 SBR16UU bearing blocks)
3pcs of ballscrews RM1605-350/650/750mm-C7(3screws+3ballnuts+3end-machinings)
3 SETS OF BK/BF12(with locknuts and cir-cplis)
3pcs Nut housings/brackets for the 1605 ballnuts
3pcs of flexible couplings 6.35mm*8mm



thanks for the reply
