For the first time, linear drive technology specialist igus is offering its linear actuators with polymer bearings, complete with motor.
Currently, the small motor range covers stepper motors in sizes NEMA17 and NEMA23. The motors are optionally available with encoder and/or brake. Stepper motors are a good accessory to the DryLin linear drives due to their outstanding cost-effectiveness, precision, and simple operation.
The new linear axis DryLin E SAW-0630 with NEMA 17 motor is driven via a trapezoidal or high helix thread lead screw. Numerous pitches from 1.5 – 15 mm are available. The drive lead screws are supported by ball bearings.
The lead screw nuts are made of tribologically optimised iglide high-performance polymers, and guarantee freedom from lubrication over the entire stroke length, and entire life of the bearing.
Almost all the components used for the ready-to-fit linear unit are made from plastic and aluminum, meaning the system is extremely lightweight.
The SAW-0630 is ideal for simple lubricant-free format adjustments, feed movements, and the handling of components. The new driven axis is available from stock within a few days, in the exact length specified, and including the motor.
The linear guide itself is based on the maintenance free DryLin W system, is comprised of a bearing housing and tribologically optimised polymer gliding film for very low friction and wear. The design makes a flexible and modular structure possible, making assembly easy.
There a numerous design possibilities to choose from, with 12 rail profiles available, single and double rail options, and the choice between individual bearings or complete slides.
These guides are also available as linear axes with a toothed belt drive.
