I've got a machine with two Rexroth/Star 15mm profile rails with two 1651-11X-10 per rail and I'm trying to determine what kinds of loads I can expect it to carry. The profile rails are 14 cm apart and I'm trying to determine how to calculate what kinds of moment loads I can safely apply to the system.
I've attached a pic of the load rating for the carriages. This is the rating for the current Bosch/Rexroth 1651 style carriage, it has the same dimensions so it should be close enough. My main issue is trying to determine how much moment will actually be applied to the bearings with them mounted in parallel, it's a statically indeterminant system and as such presents a much more difficult engineering problem than it would otherwise. With two in parallel is any moment really reacted by the bearings or does it generally transmit most of the force as direct loading to the rails?
Thanks,
Nathan
