The extremely robust MINIRAIL miniature guideways prove themselves with their high level of friction movement, precision and reliability. The styling, choice of materials and surface consistency of the ball recirculation and ball run-in ensure low pulsation and therefore, great smoothness. The highest process reliability at speeds up to 5 m/s and acceleration of 300 m/s² (30 g), interchangeable carriages, low risk of contamination thanks to the narrow gap between carriage and rail, high load-bearing capacity, low travel pulsation, and vacuum-compatibility up to 10-7 mbar. The product range includes eight rail widths which can be combined with up to four carriage sizes. High rigidity, great dynamic and static load carrying capacities, high running smoothness, and all-round seal of the carriage in the MONORAIL guideway - with rollers or with balls - ensure cost-effective, frictionless guideways while enhancing geometric accuracy and surface quality of the workpieces being processed. The high rigidity yields better vibration behavior with smaller vibration amplitudes and consequently longer tool service life.
