nPS70 Stage

Compact Stages with Cross-roller Bearings

The nPS70 are compact stages with cross-roller bearings. They are offered in both lead screw (LS) and ball screw (BS) versions. The lead screw option allows for lower cost and is especially helpful in vertical applications where self-locking is needed. The ball screw option is available for applications requiring higher efficiency, duty cycle or speed.

Combining these stages with any piezo stages creates multi-axis systems that offer up to 25 mm of positioning range and high-speed scanning necessary in Photonics, Precision Assembly and Biomedical applications.
