igus launches ultra lightweight linear drive system
igus' new drylin SLN-27 miniature linear axis has been developed specifically for simple handling tasks in confined spaces and is said to offer strong design flexibility for positioning small loads.
Available with an optional NEMA 11 certified motor, the miniature linear axis is based on the technology of the drylin N27 linear guide system and is made of high wear plastic. According to igus, it is maintenance free, self lubricating and corrosion resistant, providing a 'fit and forget' solution.
The module measures 22 x 28mm wide and is suitable for low load sensor adjustments and feed mechanisms, as well as lightweight handling tasks such as those found in laboratory equipment. Its carriage is driven by a 5mm trapezoidal or high helix thread leadscrew and is available in a range of pitches from 0.8 to 5mm. The leadscrew nuts are made of iglidur polymers, which are optimised for lubricant free operation over the entire stroke length up to 250mm.
"Weighing in at 69g, the SLN-27 is one of the feather weights of the driven linear guide industry," said Matthew Aldridge, director of igus UK. "Even with the maximum stroke length of 250mm, this miniature actuator weighs just 160g."
