Type MR
MONORAIL MR Standard
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.

Type BM
MONORAIL BM
SCHNEEBERGER's MONORAIL BM ball guideway features excellent dynamic
properties and many commercial benefits. Designed with a small
number of cleverly arranged components, it provides for excellent
running properties due to the small number of transitions in the
ball tracks, which lead to very quiet running, low pulsation and low
friction as well as high travel speeds. The use of a trapezoidal
rail section results in an extremely rigid guideway coupled with a
substantial reduction in servicing time as additional wipers can be
changed without dismantling the carriage. Complete sealing of the
carriage guarantees maximum reliability coupled with a long service
life.
This robust and economical guideway rounds off SCHNEEBERGER's range
of products for industrial applications with high demands on speed,
reliability and consistant running properties.

|
Type BZ
MONORAIL BZ
SCHNEEBERGER's MONORAIL BZ systems are high-precision linear guide
systems with integral rack drive, based on the company's proven
MONORAIL BM profile guideways with balls. The benefits resulting
from the integration of a profile guideway and an extremely precise
rack drive mainly come into their own in the handling and automation
industries, in laser and water-jet cutting tools as well as in
woodworking machines. Outlay on the production of machine beds, the
installation and alignment of the guideway and gearing are
substantially reduced. Single piece rail systems are available up to
a length of 6 metres.
The design of the MONORAIL BZ provides for superb operating
characteristics, high load-bearing capacity and rigidity together
with a long service life thanks to the use of the tried-and-tested
MONORAIL BM profile guideway and to the high transmittable forces,
smooth running and optimum positioning accuracy offered by ground,
hardened and precise helical gearing of superlative quality.
