Country of Origin Made in Switzerland. CO2 Impact By purchasing this reused component, you help avoid the emission of approximately 20.0 kg of CO2, which is equivalent to the savings from not producing a new unit. This contributes to a more sustainable industrial environment. Availability This item is in stock and ready for immediate dispatch. Order now from profideals for expert support and fast delivery. FAQ What is the difference between preload class G3 and other classes like G2 or G1?Preload class G3 signifies a zero-backlash (or “clearance-free”) fit between the carriage and the rail. This is achieved by using slightly oversized rollers, ensuring high rigidity and accuracy, which is ideal for applications like high-precision milling or measuring machines. G2 and G1 have progressively higher levels of preload for even greater rigidity. Can this MRA 55 carriage be used on any Schneeberger size 55 rail?Yes, this MRA 55 carriage is designed to be compatible with any Schneeberger MONORAIL MR 55 guide rail. However, for optimal performance and to maintain the specified accuracy (V2 class), it is highly recommended to use it on a rail with a matching or better accuracy grade. What are the recommended lubrication procedures for the MRA 55 G3-V2?This carriage has lubrication ports on the end caps and sides. It is crucial to use a high-quality lithium-based grease with an EP (Extreme Pressure) additive, typically of NLGI class 2. The lubrication interval depends heavily on the operating speed, load, and environment. Refer to the official Schneeberger MONORAIL MR catalog for specific relubrication quantities and interval calculations.
