ALS – Electro Mechanical Screw Rams

Description for ALS – Electro Mechanical Screw Rams

As a universal drive system is the "ALS" suitable for the wide range of mechanical engineering e.g. Metal processing, automotive, construction of sluices, the paper industry and others the special machine.

With a choice of 4 sizes, a modular design in "ALS" compact version and "ALSR" cylinder version it is possible to obtain the optimal design features to suit your specific requirements. The system is particularly ideal for single drive applications on linear motion projects. The "ALSR" version consists of the "ALS" standard version plus a fully enclosed shaft and piston structure, with the tubes protected against corrosion.

Available in 4 standard sizes

  • Maximum dynamic axial force of

  1. Size 10 = 12,5 kN
  2. Size 25 = 25 kN
  3. Size 50 = 50 kN
  4. Size 100 = 100 kN
  • Lifting speeds of 0.5 m/min to 10 m/min
  • With trapezoidal or ball screw
  • Direct motor attachment possible
  • Standard stroke lengths of up to 1.5 m, stroke lengths to customer’s specification based on buckling and speed diagrams
  • Special screw diameters and pitches possible
  • Standard stroke lengths "ALSR" for

  1. Size 10 = 100 / 200 / 300 / 400 mm
  2. Size 25 = 100 / 200 / 300 / 400 / 500 mm
  3. Size 50 = 200 / 400 / 600 / 800 / 1000 mm
  4. Size 100 = 300 / 300 / 900 / 1200 / 1500 mm
  • Long-term lubrication by high-quality grease and enclosed design
  • Can be used in accordance with EC Directive 94/9/EC (ATEX)

The "ALS" expansion program includes ball screws and single flange nuts, drive motors, intermediate flanges for hollow shaft drive motors, connection flanges and couplings for solid shaft drive motors as well as bearing journals (head I) on the end of the spindle and much more.

A wide range of accessories is also available, such as inductive limit switches, anti-turn device and attachment variants [flange plate (head II), rod head (IV) or joint head (III)].
