The SCHNEEBERGER MONORAIL MR 4S profile rail guide stands for the highest quality in linear motion technology. Its main features—high rigidity, high dynamic and static load capacity, smooth running, and all-round sealing of the carriage—enable precise and powerful machining. These properties result in improved dimensional accuracy and surface quality of the workpieces, as well as longer tool life thanks to optimized vibration behavior with reduced vibration amplitudes.

MONORAIL MR - Economical and future-oriented

guideways — MONORAIL MR Profiled linear roller guideways

MONORAIL MR is based on decades of experience in the design of rollers and roller guides. Combined with state-of-the-art technologies in product development and series production, the result is an economical roller guide that meets the requirements of modern machine construction.

The four “S” of MONORAIL MR 4S

The new MONORAIL MR 4S series offers four key advantages – the so-called “4S”s:

Serviceability - compatibility, exchange of cross wipers
Supply of lubricant - pressure-tight lubrication channels
Shock resistance - body optimized for rigidity
Sturdiness - robust and well-secured front plates

PULSE PRO 45 – The new generation of profile rail guides

With the PULSE PRO 45, SCHNEEBERGER presents an innovative further development of the MR45-B/D series. The new guide reduces micro-pulsations by a factor of 2 and offers 18% higher rigidity – ideal for applications with the highest demands on precision and smooth running.

Technical highlights of the PULSE PRO 45

Innovative, patented operating principle
Eight independent rows of rollers in the recirculation unit
No long carriage required to reduce micro-pulsations
Robust design with sheet metal cover and four mounting screws
Full roller guide, no chains
DIN 12090-compliant dimensions
Comparable with MR45-B/D

Typical areas of application

Applications with high rigidity and accuracy requirements
Use in limited installation space
Moderate loads up to max. 10 kN per carriage
Dynamic load capacity (C100): 60,000 N
Static load capacity (C0): 227,500 N

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.
