SIMO Series

Linear Actuator Technology

The SIMO® Series enables multiple application requirements to be met with a single platform. Flexible with a uniform geometry as a base with a large number of selectable options in the basic design, drive type and type of guide. The mix and match platform within the same design environment allows configurations to be easily and quickly adjusted.

The SIMO Series: Design It Your Way

Do I need a low profile rail or a structural support rail?

Rail Heights Options:

Each aluminum base rail is uniquely qualified with the SIMO process (Simultaneous Integral Milling Operation).

  • UGA low profile for tight spaces
  • UGT tall profile for greater structural integrity
UGA low profile for tight spaces
UGA low profile for tight spaces
UGT tall profile for greater structural integrity
UGT tall profile for greater structural integrity
What performance do I expect from the bearing system?

Gliding options:

  • self-lubricating, maintenance free gliding system (GST) which are ideally suited for contaminated environments
  • V-wheel roller bearings (CRT) for high speed applications

How will I drive it?
Lead screw with multiple leads
Lead screw with multiple leads
The self-lubricating polymer nuts and lead screws provide good rigidity, vibration damping, and consistent performance.
Belt drive
Belt drive
2 versions: horizontal belt and motor mount for the UGT tall profile and vertical belt and motor mount for UGA low profile rail
Which motor suits my needs?

Motor options:

  • Integrated motor with welded lead screw – Integrated threaded spindle aligned to the motor and attached directly to it. Thus high accuracy and fewer fastening elements.
  • Motor mount options for attaching own motors.
How will I mount it?
  • HAND KNOB
    Hand adjustment knobs are used for manually adjusting screw driven systems.
  • SENSOR BRACKETS
    Sensor brackets accommodate a variety of sensor types
  • TOE CLAMPS
    Large and small toe clamps are available to secure the (UGT) tall rail to the mounting surface
  • HAND BRAKE
    Hand brakes are used to manually lock position in the GST screw driven systems
  • MOTOR MOUNT
    Motor mount option for attaching a stepper, servo, or smart motor, etc.
  • MULTI-AXIS MOUNTING PLATES
    Mounting plates are available to easily configure multi-axis systems
