Chieftek Precision USA supplies a wide array of miniature linear guides as well as direct-drive tables, linear motors, feedback components, and servo drives to the medical-device industry.
In fact, the manufacturer’s original offering was its linear guides — and today, Chieftek precision miniature rail MR guides continue to lead in all industries.
More specifically, 3-mm miniature linear guides as well as 5-mm versions from Chieftek are widely employed around the world. Now, the manufacturer has added an even smaller version of this precision product to its lineup: These are 2-mm miniature linear guides specifically targeted to medical devices and lab automation.
These MRU 2M series 2-mm miniature linear guides are so called for being 2 mm in several key dimensions:
High power density from the 2-mm linear guides makes for high load capacity from a small design footprint. These load capacities are calculated according to ISO 14728. To compare the rating life definition and the load capacities use the C50B = 1.26 x C100 equation.
Design engineers can source customized linear components from this series — and in fact, slides from Chieftek come in mostly custom lengths (even to many feet long). The manufacturer uses precision cutting and grinding processes on these miniature slides to maintain accuracy.
Engineers can also choose:
- the number of runner blocks (carriages) to ride the linear-guide rail
- the number of sections of separate rail to form a given axis
- various sealing options for carriage end sealing and bottom sealing
- an optional lubrication-storage plate to store oil inside the carriage block
- an accuracy grade of normal, high, or precision
- starting and end linear-guide rail mounting hole pitches
- a preload value for clearance, standard fit, or light preload
