Drive systems The SNR AXE linear axes series are equipped with toothed belt drive, which makes them suitable for fast handling and positioning applications. All linear axes are equipped with AT or STD toothed belt drives. These are extruded polyurethane belts with integrated steel cords. The AT toothed belt drives are of zero-gap shape. Using black toothed belts prevents discoloration of the toothed belts under UV - radiation. These toothed belts have the following features: • Low wear • Maintenance free • High tensile strength and low elongation • High precision – pitch error ± 0,2mm/m • UV...
