The TH linear actuator features a high-rigidity aluminum extrusion frame with LM guides and offers a choice between two drive systems: ball screw or timing belt drive. The LM guides are available in sizes 20 and 25, and ball screws up to 25mm in diameter can be mounted. The maximum stroke is 2600mm for the ball screw type and 3600mm for the timing belt drive type.
THK flexibly accommodate customizing requests to your meet needs such as
・Non-standard lengths
・Right/Left Screw Thype
・Custom motor mounting brackets, etc.
Please contact with THK via Chat, local contact, distributors.

Note)
The belt-driven type is intended for horizontal use. Please be aware that it cannot be used vertically.
In addition, contact THK if you will be mounting the product on a wall.
Multiple Options Available for the LM Guide Units
The TH uses two Caged Ball LM Guide units, which makes it suited for transferring heavy objects.
-
SSR:
The ball contact structure is resistant to loads in the radial direction, making this type of guide ideal for horizontal use.
-
SHS:
This type of guide bears loads equally in four directions, so loads can be applied from any direction (radial, reverse radial, and horizontal).
Note) The belt-driven type is intended for horizontal use.
Optimal for High-Speed Transfers over Long Strokes
The TH features an aluminum base, and this linear actuator is suited for transferring objects over long strokes.

Light Weight and High Rigidity
The cross-section of the extruded aluminum base features hollow areas, making it both lightweight and highly rigid.
Many Accessories Available
Optional covers, bellows, sensors, and cable carriers are available. A QZ Lubricator can be attached to the LM Guide and ball screw units to enable long-term maintenance-free operation.
