new roller coaster design 1

[duk748]

hello all - i have an idea for a linear transfer device
for a machine at our company - i would like to design something similar to the way the new roller coasters are designed w/ tubular rails & roller assemblies running on them - anyone have any info or direction that i may find some info on the rails or the roller assemblies?? - suppliers or parts manufactures?? - any help would be very appreciated - thank you

Lots of companies doing factory automation have that sort of thing. I don't recall any names, offhand, but the semiconductor industry is one that uses rollers, rails, etc. in manufacturing to move materials around.

hello again - thank you for the reply but the type of machinery that we build is much much larger then some of the equipment used in the semi conductor industry - this equipment must move items weighing 200# or more - i am looking for a more inexpensive transfer method then commercial linear rails/shafts(i.e. thk or thompson, etc.)
my idea was to bend tubular steel & make or buy rollers like a roller coaster - any other help would be apprecaited - thank you

Google for term "cam followers", you should find people like McGill or Emerson Power Transmission. Dynamic load ratings in excess of 200lb are cheap and common.
