LIGHT 30 50 80 LIGHT series: This is the Linear Units with the best ratio between quality and price that you can find today in the market. Available in three different sizes (30, 50 and 80 mm), it has a self-supporting structure made by a square-section of extruded aluminum. The distinguishing features of this simple but cost-effective unit, which also guarantees high level of quality, are an AT pitch driving polyurethane belt reinforced with steel wires, ball recirculating linear guides with two preloaded carriages, as well as the "maintenance-free system" above described. Reduced costs and dimensions mean that this series can be used in sectors where pre-assembled units were once out of question and therefore such as on large production series.
