igus DryLin SLN-27 miniature linear axis

The DryLin SLN-27 from igus is a small, lightweight and lubricant-free system for positioning small loads that comes with an optional NEMA 11 certified motor. Developed specifically for simple handling tasks in confined spaces, the high-performance miniature linear drive offers design flexibility for positioning small loads.

The DryLin SLN-27 miniature linear axis is based on the DryLin N27 linear guide system. The linear rail of both the N27 and SLN-27 is made of durable anodised aluminium. The plastic carriage has high wear resistance and is also maintenance-free, self-lubricating and corrosion-resistant, providing a ‘fit-and-forget’ solution.

With dimensions of 22 x 28 mm, the product is suitable for low-load sensor adjustments and feed mechanisms, as well as lightweight handling tasks such as those found in laboratory equipment and camera inspection machinery.

Lightweight plastics and aluminium make the device very robust. The carriage is driven by a 5 mm trapezoidal or high-helix thread lead screw and is available in a range of pitches from 0.8 to 5 mm. The lead screw nuts are made of iglide high-performance polymers which are optimised for lubricant-free operation over the entire stroke length, which can be a maximum of 250 mm.

The unit can be bought as a complete system with a NEMA 11 stepper motor, still achieving compact dimensions, and is made using stock components, individually configured to the required length. The company also offers a ‘quick-fit’ aluminium spacer and motor flange connection to fit a third-party NEMA 11 motor.
