Schneeberger MR Profiled linear ball guides MR W 45-C-G2-V1

Product Description

MONORAIL MR Profiled linear roller guideways

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.

MONORAIL MR 4S – next carriage generation

4 reasons to love the new SCHNEEBERGER MONORAIL MR 4S series: An optimized lubrication system, ease of maintenance, shock resistant, and dirt repellent

● 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

Features of Schneeberger MR W 45-C-G2-V1

High Rigidity and Load Capacity

Constructed from through-hardened bearing steel, the carriage offers both a high static load capacity (up to 324,000 N) and robust dynamic load ratings (around 180,500 N). This makes it suitable for heavy-duty operations where stiffness and stability are paramount. 

Optimized Roller Geometry

The use of rollers with a logarithmic profile minimizes friction and provides very smooth motion. This optimized geometry reduces pulsation and enhances both speed and acceleration performance, with maximum speeds of up to 3 m/s and accelerations around 50 m/s². 

Enhanced Lubrication System

The design includes multiple lubrication connections (positions for lube holes, such as center front and lateral positions) that ensure even distribution of lubricant. This minimizes leakage and extends service life while supporting continuous operation in demanding environments. 

Complete Sealing and Protection

The carriage features comprehensive sealing to protect internal components from contaminants such as dust, coolant, or metal chips. This, along with the option for various coatings (e.g., CN for corrosion protection), contributes to a long service life even under harsh conditions. 

High Accuracy and Preload Stability

With a G2 accuracy class and a V3 preload rating, the MR W 45-C-G2-V1 is designed to maintain high precision and minimal backlash, even under heavy loads. This ensures consistent positioning accuracy, which is critical in high-precision machine tools and automated systems. 

Modular Design and Versatile Installation

The carriage is available with various mounting options and fixing hole arrangements. Its dimensions (e.g., system height, carriage width, and length) allow integration into a wide range of machine designs, from compact systems to large-scale industrial applications.

Application Areas

● CNC Machine Tools

Its high rigidity and precision make it ideal for CNC milling, turning, drilling, and grinding machines where accuracy and high-speed performance are essential.

● Automation and Robotics

The smooth, low-friction operation combined with excellent load capacity supports applications in robotic systems and automated assembly lines, especially where repeatability and precision are required.

● High-Load Transport Systems

In industrial material handling or large-scale positioning systems, the carriage’s ability to withstand high static and dynamic loads ensures reliable performance even under significant forces.

● Precision Measurement Systems

When integrated with measurement technology, the stable and precise motion characteristics are beneficial for metrology and inspection equipment in semiconductor or electronic manufacturing.

● Heavy-Duty Industrial Equipment

Applications such as large presses or heavy machining centers benefit from the carriage’s robust construction, which minimizes vibration and ensures consistent performance under cyclic loads.
