RODLESS ACTUATORS; SCREW DRIVEN

Screw driven actuators are used for applications that involve high loads and moments. Our product range of screw driven actuators includes the POWERLine and the DYNALine, both below.

POWERLine

Precision Technology WIESEL™ linear drive units guarantee the optimum solution of technology and economy for every drive task due to their high loads and moments.

 

Precision Technology WIESEL™ mechanical linear drive units have played a leading part in plant engineering for many years thanks to their innovative design details.

 

With its comprehensive product range, Precision Technology has the right linear drive unit in the right size for every application. The high performance and modular design make it possible to replace a large number of individual components, thus permitting modular systems with lower costs and shorter lead times.

 

All of our products can be customized for application in your system. In-house research, development, design and production are backed by our Total Quality Management guarantee to ensure that our products and accessories meet the highest possible standards. The POWERLine should be used where high forces and precision at average speed is needed.

Technical features:

 

  • Maximum speed 2.5 m/s (8.2 ft/s)
  • Minimum repeatability2) ± 0.01 mm (0.0004 in) res. ± 0.05 mm (0.002 in)
  • Maximum feed force 12 kN (2698 lbf)

 

WIESEL™ POWERLine® WM40

 

The linear drive unit for miniaturized applications. High performance with extremely small dimensions. The Precision Technology ball screw drive in combination with the high precision linear guide allows precise positioning.

 

  • Fully integrated miniaturized linear drive unit with linear ball guide, ball screw drive.
  • Patented sealing strip - The patented sealing strip protects the mechanism effectively from dirt. The friction for the deviation of the sealing strip is reduced to a minimum.
  • Screw support - The patented screw support system permits high speeds (max. input speed) at long strokes.
  • Central lubrication - A standard feature. The drive and guide systems are conveniently re-lubricated from a central point on the power bridge.
  • Linear guides - Precise positioning is made possible by a polished linear guide with a high degree of guide accuracy. A small motor can be added thanks to the low coefficient of friction. Rubber wipers protect the mechanism from dirt, thus increasing service life.

 

WIESEL™ POWERLine® WM60/80/120

 

The WIESEL™ POWERLine® is an extremely powerful linear drive unit with ball screw drive and integrated ball-bearing guide. It allows high feed forces and load moments in all directions.

 

  • Fully integrated linear drive unit with ball screw and linear ball bearing guide and sealing strip.
  • Transmission of the feed force and handling of loads and load moments.
  • Size WM60/80-370 with short guide system.
  • Well proven and patented guide system - The high-performance linear ball-bearing guide with hardened steel running tracks has been integrated into the aluminum profile. Optimum introduction of forces permits maximum force and torque, as well as optimizing the tensile stresses. the ball bearings of the linear guides are protected by a ball cage. These can be replaced quickly and safely.
  • Optimized ball screw - The pre-tensioning of the nut unit can be adjusted by the Precision Technology service team. This increases the lifetime of the axis.
  • Self-adjusting third generation cover strip - The patented sealing strip reliably protects the mechanical parts against excessive dirt and is re-tensioned automatically. Result: the maintenance effort is reduced to virtually zero.
  • FEA optimized design - Both the profile and the entire linear drive unit have been modeled and optimized by finite element analysis (FEA). Result: maximum performance density and reliability.

DYNALine

The WIESEL™ DYNALine® permits high feed forces, even in combination with long stroke lengths and high speeds. The supported, covered ball screw must be used in combination with external linear guides.

 

  • Optimized ball screw - The pre-tensioning of the nut unit can be adjusted by the Precision Technology service team. This increases the lifetime of the axis.
  • Self-adjusting third generation cover strip - The patented sealing strip reliably protects the mechanical parts against excessive dirt and is re-tensioned automatically. Result: the maintenance effort is reduced to virtually zero.
  • FEA optimized design - Both the profile and the entire linear drive unit have been modeled and optimized by finite element analysis (FEA). Result: maximum performance density and reliability.
  •  Used in combination with external linear guides.
