Two new motorized elevator stages, the DAG20-120-01, and the DAG20-120-04 have been released by Optimal Engineering Systems, Inc. (OES). These high resolution, compact, low profile elevator stages feature high stability 120 mm x 120 mm tables and 20 mm of vertical travel. High precision ball bearing profile rails assure very high parallelism and smooth motion throughout the raising and lowering of the table. These Z-Axis Stages are ideal for Microscopy, inspection, metrology, positioning, photonics, sampling, and laser drilling and machining.

Driven by Two-Phase Stepper Motors, the DAG20-120-01 and the DAG20-120-04 Motorized Elevator Stages feature 2-micron positioning accuracy, and resolutions of 0.03 microns (with a 10 Micro-steps per step motor driver in use). The knob for manual adjustment on the DAG20-120-01 (shown) is replaced with a Quadrature Incremental Optical Encoder for position verification on the DAG20-120-04. The load capacity of these compact stages is 20 kg.

These compact, black anodized aluminum alloy stages measure 181.8 mm x 120 mm x 115 mm high at the raised position. Speed of travel is 5 mm per second and limit switches prevent over travelling. The table of each stage has a precise pattern of threaded holes for fixtures or tooling, and holes in the base allow for easy integration into a new or existing application.

These stages require a Motion Controller that can be ordered as a complete plug-and-play system with RS-232, USB, joystick, trackball, and keypad control.

2022 New Week WSW product Recommendation:

Angular Contact Ball Bearing:

WSW excellent quality Angular Contact Ball Bearing with reasonable price for customers all over the world and can produce various types of bearings,over 200 series and 5000 specifications or so. Angular contact ball bearing can bear radial load and axial load at the same time. It can work at high speed. The larger the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the connecting line of the contact point between the ball and the raceway in the radial plane and the vertical line of the bearing axis.
