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 actuator is suited for transferring objects over long strokes.
