TH actuators are rigid and compact linear units with ballscrew drive, enabling high positioning accuracy and repeatability in all process phases with optimal performance assured.
Thrust force transmission is achieved by means of super high efficiency ball screws, which are available in several precision classes and a variety of leads. Linear motion is based on two or four preloaded recirculating ball bearing blocks -- with ball retainer technology -- mounted on two precision aligned parallel rails. The TH series is available in the single carriage or double carriage versions to meet different load requirements.
Use of these elements achieves optimal static and dynamic capacity and high positioning accuracy within 0,02 mm and repeatability within 0,005 mm.

The TH series ensures maximum protection of internal components through use of extruded profiles, aluminium cover and two cross-linked polymer protection belts with molded-in polyester reinforced cables. Protection against external agents, dust, dirt and impurities is therefore ensured even in harsh working environments.
TH linear units also feature safe and separate lubrication of guides and screws via a system of dedicated fittings and channels for each component.
The extremely compact structure of the TH actuator makes it ideal for all limited space applications.

The actuator is currently available in the TH145 version with maximum strokes up to 1700 mm. The new TH110 version will be available soon with strokes up to 1400 mm.

The T-slots on the profile and threaded steel inserts on the carriages make the TH series completely modular and suitable for use in multi-axis systems.
The TH series effectively meets the needs of all applications that require a high level of precision, compactness, protection and stiffness and it is an effective ready-to-use bolt-down solution for Engineers, Designers and Technicians requiring optimum performance in a linear motion system.
