MONORAIL MR Profiled linear roller

High rigidity, great dynamic and static load carrying capacity, outstanding running smoothness and the total enclosure of the carriage are the main features of the MONORAIL guideway. These properties result in higher machining rates while enhancing geometrical accuracy and surface quality of the machined workpieces. Our highly rigid MONORAIL provides improved vibration behavior, smaller vibration amplitudes and thus extends tool life.

SCHNEEBERGER has systematically applied its many years of experience in the design, production and use of roller-type anti-friction guideways in the development of the MONORAIL. Consequently the MONORAIL MR is a cost-effective anti-friction guideway which meets the challenge presented by modern machine design.

Significant customer benefits of MONORAIL: simple, versatile lubricating options and guide rails up to 6 meters in length – reduced number of butt joints and resulting installation costs.


Article/Example of application

  • No compromises with choice of the delivery supportSCHNEEBERGER MONORAIL profiled linear guideways bring high levels of flexibility for indexable insert grinding machines.
  • High-performance profiled guidewaysWhen the heaviest loads in milling, turning, drilling or grinding machines need to be moved in an accurate manner, reliable linear bearings are one of the elements required for this. Schneeberger has the right solution in the form of its MONORAIL MR series, which is intended for various types of application and weight class. As such, workpieces weighing up to 150 tons can be moved in an extremely precise manner.
