Precision System

High precision and high axial forces
High mechanical performance
Low wear and tear
Low resistance to movement
High speed (for long pitch screws)
TH linear actuators are rigid and compact, ball screw driven linear units, enabling high positioning accuracy and repeatability in all process phases with optimal performance assured, with a repeatability within 5 µm.
The TT is a linear actuator series mainly used for high accuracy positioning within a 10 µm range and precision repeatability within 5 µm. Manufactured using a very rigid extruded anodized aluminum base structure, this actuator series is designed for high loads and precise movements that are typically required in machine tools and other exacting machine design applications.
All mounting surfaces and reference datums have been produced to significantly reduce the deviations of pitch, yaw and roll along the entire stroke. The heavy duty carriage is driven by a C5 or C7 preloaded ball screw drive and the payload is supported by a system of four runner blocks mounted on two parallel linear guides. High speeds can be accomplished by specifying available super lead ball screw drivers.
Linear units of the TV Series have a rigid anodized aluminum extrusion with square cross-section (rectangular in the case of TV 140), the transmission of motion is achieved by means of a precision C5 or C7 rolled ball screw drive.
The 'TK' series linear units are made entirely of steel which allows high load capacity and high precision positioning and repeatability with very compact dimensions. This series can be dimensionally interchanged with other popular ball screw driven actuators.

* In order to reach sufficient static safety, we recommend using max. 20% of the theoretical value.
** In order to reach sufficient static safety for the toothed belt, we recommend using max. 80% of the theoretical value. *** Longer stroke is available for jointed version. |
