Abstract
Abstract A machine tool has an elongated bed and includes a carriage supported for reciprocal movement longitudinally of the bed by a roller support assembly which comprises a pair of transversely spaced and longitudinally extending roller units positioned between the bed and carriage and in rolling engagement with both the bed and carriage. Each roller unit includes an elongated support member which carries at least one group of cylindrical rollers. The rollers are arranged in longitudinal series and journalled on an associated set of axles mounted in cantilever position along the support member.
