Screw Driven Modular Linear Actuators

Screw Driven Modular Linear Actuators use the finest acme and ball screws manufactured in the world. They allow for direct in-line motor mount with or without an in-line or parallel gear box.

V Groove Guided

An aluminium square profile with lateral V-guides. The carriage (screw driven) moves along the unit guided by adjustable V-slides that are adjustable free of play. Where two linear units are used in parallel (or two carriages are mounted on one unit), the leading-nut receiver can be used to adjust the symmetry of the carriages. The linear opening of the
unit is sealed with a stainless steel cover band to make the unit splash-proof and dust-tight.

  • Fitting position: As required. Max. length 3,000 mm
  • Carriage mounting: T-slots, tapped holes (size 40)
  • Unit mounting: By T-slots or tapped holes in the bearing block, mounting sets.

External Roller Bearing Guided

An aluminium hollow section with integral, parallel ground and hardened steel guide rods. The carriage has play-adjustable ball-bearing rollers which engage with the guide rods. The rotating screw causes linear motion of the ballnut, which is connected to the carriage. The slot necessary for this is covered by a stainless steel strip, making the unit dust- and splash-proof. Lateral adjustment of movement for parallel units (or when two carriages are mounted on one unit) is provided by the ballnut mounting.

  • Fitting position: As required, max. length 3,000 mm
  • Carriage mounting: By T-slots and tapped holes
  • Unit mounting: By T-slots and tapped holes in the mounting surfaces.

Internal Roller Bearing Guided

A rectangular aluminium profile with 2 integrated roller guides. The carriage is driven by means of a rotating spindle with leading nut. Where two parallel linear units are used (or where two carriages are mounted on one unit) the leading-nut receiver can be used to adjust the symmetry of the carriages. The openings of the guide body are sealed with 3 stainless steel cover bands to protect the drive from splash water and dust.

  • Fitting position: As required. Max. length 3,000 mm without joints.
    Carriage mounting: By T-slots.
  • Unit mounting: By T-slots and mounting sets. The linear axis can be combined with any T-slot profile.
  • Carriage support: In the standard version, the carriage runs on 8 rollers which can be adjusted and serviced at a central servicing position.
    For longer carriages, the number of rollers can be increased. Repeatability ballscrew ± 0.025 mm, trapezoidal thread
    ± 0.2 mm.
