Power for automation

With the SLD series, Schunk introduces a new generation of linear direct axes. The dynamic, heavy-duty axes with electric linear direct drive ensure short cycle times and more productivity in high-speed assembly and handling processes in the fields of electronics manufacturing, e-mobility or life science.

The SLD series was developed as a dynamic all-rounder that can meet the requirements for higher load ratings and longer service life. At the same time, automation expert Schunk is expanding its portfolio of linear direct axes with this series and, thanks to its modular design, enables an attractive price/performance ratio. Two sizes are currently available for a wide range of applications, each with four different motor sizes that provide drive forces up to a maximum of 2.4 kN and load capacities of up to 106 kN. Further versions will follow.

In the compact axis, the electric drive and the displacement encoder are already integrated, enabling agile, space-saving motion sequences. Accelerations of the direct drive of up to 100 m/s² and speeds of 5 m/s ensure high dynamics and short cycle times. At the same time, the drive ensures an accuracy of ± 0.01 mm for the user. Its elements operate without mechanical play, which eliminates wear parts and keeps maintenance requirements low. In addition, the drive can be designed in any length without compromising performance. The linear direct axes of the SLD series are UL-certified as standard. This is the prerequisite for rapid access to the US and other markets.

Options increase the range of applications

As a decisive component of the SLD axes, the profile rail guide enables compact design and the transfer of high loads. Strokes of up to 6,000 mm can be realized. The use of a cover not only prevents dirt and dust from entering the inside of the axis. It also enables the use in areas with coarse, sharp-edged or hot foreign bodies. This sets the course even for use in harsh environments. In addition, the cover prevents grease from escaping during overhead assembly.

Schunk offers the series with numerous options, including a holding brake that prevents gravity-loaded axles from dropping or falling unintentionally. This ensures safety in the application. Mounted under the carriage and pneumatically actuated, the brake reliably engages in the event of a power failure. In addition, the linear direct axes use a modular encoder system with the proven Hiperface/HiperfaceDSL, DRIVE-CLiQ, Sin/Cos and SSI interfaces. All encoders are also available in SIL2/PLd. Customer-specific measuring systems can also be integrated on request.

The SLD series offers a whole range of mounting, installation and combination options. The linear direct axes can be easily combined by means of an adapter plate, attached by clamps and used in a variety of applications. Due to their high dynamics and load-bearing capacity as well as long service life, the axes are predestined for industries such as electronics and electrical engineering, food and packaging, life science and assembly automation through to photovoltaics and automotive engineering. In e-mobility, for example, the handling of prismatic cells can be implemented just as efficiently as in hairpin applications with high demands on flexibility, dynamics and precision. Schunk is expanding its digital services for easy configuration and design of its electric linear axes and is planning a practical configurator before the end of the year.
