Item # A-624.050, A-62x PIglide RM Rotation Stages with Air Bearings
Friction-free, ideal for indexing, positioning, scanning, measuring technology
Cleanroom compatible
Can be mounted vertically or horizontally
The PIglide RM series of motorized rotation stages are designed for accuracy, precision, high stiffness, and ease of use, and can be mounted in any orientation.
Various options can be combined to create a solution ideal for point-to-point indexing or constant velocity scanning.
The RM stages offer superior travel accuracy, flatness, and wobble performance. Because they are friction free and require no maintenance or lubrication, they are ideal for use in cleanrooms.
Absolute encoder (optional)
Absolute encoders supply explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation.
Application fields
Optical alignment, metrology, inspection systems, calibration, scanning.
