Linear Screw Actuators With Low-Profile Guide Rails: drylin® SLW

drylin® SLW/SAW are lead screw-driven actuators equipped with fully-supported guide rails, offering more rigidity and resistance to twisting than shaft-guided actuators, like our HTS product line. They are high-performance, low-cost, low profile and highly flexible, and therefore are some of our most popular actuator series.

Benefits:

Fully supported rails for torsion-resistance
Lower cost than ball bearing actuators
Low-profile and low-weight
Grease-free & corrosion-resistant
Highly flexible, with many accessories and materials
Motors and drive controls available

Typical Applications:

Packaging machine format and lane adjustments
Lab machinery
CNC Machine Gantries

Applications for drylin SLW linear actuators

Heavy things become easy, positioning with no maintenance

In the filling systems of Fricke Abfülltechnik GmbH & Co. KG, a drylin SLW linear axis ensures that the 80 kg filling head can be easily positioned over the container.

SLW linear unit with spindle drive in medical technology

Sasyaka Engineering Services Pvt Ltd uses a linear module with spindle drive from the drylin SLW range for a conveyor belt for the pharmaceutical sector. The absence of external lubricants and the fine adjustment of the linear module gave the linear axis system from igus the contract.

Level packing and lamination

10,000 siliconized paper strips per hour - with the drylin SLW linear unit

Bernhardt Maschinenbau oHG opted for the folding and gluing machine for the SLW linear unit. The machine manufacturer wanted a self-lubricating and maintenance-free linear axis system with a long service life. The drylin SLW linear unit fulfills every requirement.
