We continuously develop and innovate our linear units so that they can be used for almost every application in the field of mechanical and plant engineering.

Vacuum technology has meanwhile become an integral part of production and manufacturing technology as well as of food, chemical and medical engineering.

Safety is especially important in places where flammable materials are handled. Above all, this applies to linear systems in the chemical and petrochemical industries and in the oil and gas production industries. We offer linear units specially optimized with regard to explosion protection, which fulfil the ATEX Directive 2014/34/EU with the standards:

  • ISO 80079-36:2016
  • ISO 80079-37:2016
  • Technical Rules for Hazardous Substances (TRGS) 727

Linear systems for clean-room applications are used for special production processes in the semiconductor, medical, optical, laser, food and aerospace industries. Our linear units do not exceed the maximum limits for particle values ≥ 0.5 μm/m³ and are thus certified according to the following clean-room classes:

  • US Federal Standard 209E Class 1 – 100.000
  • VDI 2083 Class 1 – 6
  • ISO 14644-1 Class 1 – 8
  • E-Series– linear systems in a stainless steel shell for clean surfaces

Based on our linear units, we develop clever multi-axis systems with ball screw, linear motor, toothed belt or toothed rack drive for industrial automation. Thanks to our highly qualified staff and our comprehensive and modular product portfolio we can offer customized solutions for the following areas of application:

  • Mechanical and plant engineering
  • Order picking and storage systems
  • Packaging and materials handling technology
  • Assembly lines and palletizing systems
  • 3D printing

Corrosion protection is an essential requirement where water and moisture play a role. Splash water influences, water vapour exposure or rinse water contact – our corrosion protected linear system variants withstand all these conditions due to their combination of anodized aluminium and steel components made of A2 steel.

  • Entire product range also available with corrosion protection
  • Corrosion protected variants for exterior protection
  • Expanded corrosion protection options for complete protection
  • E-Series– linear systems in a stainless steel shell for clean surfaces

Safe lifting and vertical positioning of loads: these are the challenges for lifting systems. Highly dynamic toothed belt axes with Omega deflections and fixed drives or accurate positioning systems with spindle drives – our stroke-optimized linear systems offer robust solutions with optimum performance characteristics.

  • Highly accurate ball screws with repeating accuracies up to ± 0.02 mm
  • Powerful trapezoidal thread drives with self-locking device for safe lifting
  • Ready-to-use solutions for freight elevators
  • Highly dynamic linear systems with toothed belt drive
