I agree with Dennis, we use profile rail ( THK, HiWinn, Nook, Bosch etc.) all the time on the special machines we produce. And they are the best option. You can get non-bearing type too depending on your application. I am just chiming in, because your tolerances are very tight and I am not sure these rails will get you there. Mcmaster is a great company, if you email them they answer quickly. I would ask what the tolerance per ft. is with these. If you can loosen your tolerance or if they meet your requirements they are def. the way to go, Also if you contact a profile rail distributor, they can spec something out for you - ie. a higher preload blocks for tighter tolerances you can buy. These can be really stiff to move.. (depending). ?Sometimes if we are using profile rail for only material handling we order the blocks with a lower tolerance (or we replace with slightly smaller balls) because we do not need the accuracy and /or are mounting to an imperfect surface over many feet. Just my $.02 but you should be able to find something? for your application in your price range. -Dave ?

Tim, take a look at McMaster Carr part numbers 6250K32, and 6250K34 on their website mcmastercarr.com. These two items are within your $500 budget. The rail can be mounted to something solid, and shimed to be true to your specifications. There are many other sizes and options to choose from.. One of the larger rails may even work unsupported throughout except at each end. Denis K.
