Linear Units

What is a linear unit?

  • A linear unit is a device that can move a part, product or machine.
  • It is designed to carry load in any direction.
  • It protects the mechanical building blocks it is made of from dust dirt and sometimes also water.

The linear units can be ordered with (internal) ball guide, with (external) wheel guide - as well as - (internal) prizm guide. In case of massive side loads units can be ordered with long coaches and double coach design also avaiable.

Ball screw driven - ball guided units

PowerLine, ForceLine, Microstage, AccuSlide

Typical Applications

Typical applications are where high accuracy and load capability is required but where speed is less important. Typical examples are machining operations and in the handling of heavy goods that need accurate positioning.


Technical Presentation

  • Screw support: Patented screw support system permits high speed at long stroke lengths while reducing the stroke with a minimum.
  • Double ball nuts: Double pre-tensioned ball nuts improve the accuracy and permits re-tensioning - increasing the lifetime of the unit.
  • Central lubrication: One central lubrication point on the carriage services the entire unit resulting in a minimum maintenance requirement.
  • Ball guides: Integrated patented ball guides with hardened steel tracks for optimum performance.
  • Ball cages: The balls in the ball guides are protected by a ball cage ensuring extended life.
  • Cover band:The patented self-adjusting cover band protect the unit from the penetration of dirt, dust and liquids.

 

Ball screw driven - slide guided units

BaseLine, Movopart

Typical Applications

Typical applications are where low to medium loads need to be moved at low to medium speed. These units are also suited for harsh environments. Typical examples are all types of machines in the food, chemical, paper and wood working industries.
Materials handling is another area where these units are ideal.

Technical Presentation

  • Cover band: The durable plastic cover band protect the interior of the unit from the penetration of dirt, dust and liquids.
  • Central lubrication:One central lubrication point on the carriage services the entire unit resulting in a minimum maintenance required.
  • Slide guides: The robust and accurate slide guides can be easily replaced by the user whenever required.
  • Drive:Select between the fast high precision ball screw or the robust lead screw with composite nut.
  • Screw support:The screw support system reduces noise and vibrations and permits high speeds at long stroke lengths.

Belt driven, ball guided units

SpeedLine, Movopart, ForceLine, Microstage

Typical Applications

Typical applications are where medium accuracy, speed and load capability is required. Typical examples are cutting, welding, glueing and assembly operations and in materials handling applications such as palletizing and pick and place operations.

Technical Presentation

  • Cover band: The patented self-adjusting cover band protects the interior of the unit from the penetration of dirt, dust and liquids.
  • Central lubrication: One central lubrication point on the carriage services the entire unit resulting in a minimum maintenance required.
  • Belt drive: The belt is protected from the outside ensuring long, accurate and safe operation.
  • Ball guides: Integrated patented ball guides with hardened steel tracks for optimum performance.

 

Belt driven - slide guided units

Movopart

Typical Applications

Typical applications are where low loads need to be moved at medium speed and high acceleration at low cost. These units are suited to harsh environments. Typical examples are for machines in the food, chemical, paper and wood working industry, in materials handling, cutting, scanning and printing applications.

Technical Presentation

  • Cover band: The self-adjusting magnetically sealed stainless steel cover band protects the unit from the penetration of dirt, dust and liquids.
  • Environmental protection: The unit operates in harsh environments, but is also available in wash down or chemically protected versions for the toughest environments.
  • Belt drive: The belt runs on the inside of the profile and can easily be re-tensioned without removing the load from the carriage.
  • Prism slide guides: The patented self aligning prism slide guides are accurate, durable and resistant to vibrations and shock loads.

 

Belt driven - wheel guided units

SpeedLine, ForceLine

Typical Applications

Typical applications are where low to medium loads need to be moved at high speed and acceleration. Typical examples are in packaging, cutting, pick and place and materials handling applications where the cycle times are critical.

Features

  • Can be installed in all directions
  • Speed up to 11 m/s
  • Acceleration up to 40 m/s2
  • Stroke up to 11 m

Technical Presentation

  • Belt tensioning: The belt can easily be replaced or re-tensioned from the outside of the unit without the load being removed from the carriage.
  • Belt drive: The steel reinforced belt is wear resistant, highly efficient and very accurate even at high speeds and loads.
  • Wheel guides: The H-type arrangement of the guides allows for quick movement and high forces and torque.
  • Central lubrication: The guides are lubricated from a central point that is easy and fast to access.
