The curved guide rails with the product designation AT9020 are elements of the XTS guide rail system from Beckhoff. They are made of aluminum with an abrasion-resistant hard anodized aluminum coating and enable a lubrication-free system concept in combination with the plastic rollers of the movers. The AT9020 curved guide rails enable track layouts on the basis of the AT202x motor modules (22.5° curve segments of a circle with a diameter of 1273 mm), in combination with an AT2000 straight motor module. In addition, the guide rails can be ideally combined with other straight or curved guide rails, so that individual travel paths can be realized as if from a modular system.
