Features

A 4-point contact system provides stable support for variable and complex loads. In addition, the structure maintains smooth motion even under demanding conditions.
The finite-track design with a bearing cage also improves running accuracy and reduces wear during long-term use. Furthermore, the pre-load reduces play, ensuring precise positioning and higher rigidity.
A redesigned sensor rail minimizes sensor protrusion, and as a result, installation becomes safer and more compact.
