New Vacuum Compatible UMR High Load, Double-Row Ball Bearing Linear Stage
New Vacuum Compatible UMR High Load, Double-Row Ball Bearing Linear Stage
UMR Series Vacuum-Compatible Double‑Row Ball Bearing Linear Stages are engineered for smooth, precise motion in demanding low‑outgassing environments. Their robust stainless‑steel construction and double‑row ball bearings deliver excellent linear travel and high load capacity while maintaining reliable performance under vacuum. The moving carriage is spring‑preloaded to ensure constant actuator contact and backlash‑free motion. Vacuum‑compatible actuators are sold separately.
- Designed for 10⁻⁶ Torr high vacuum environments
- Stainless‑steel for excellent stability, rigidity, and low outgassing
- Compatible with vacuum BM micrometers (sold separately)
- Centered load capacities up to 900 N See All Features

2-Axis Assembly
UMR Series stages can be easily stacked together to provide 2 axes of translation for a low profile XY system or as a foundation for more complex multi-axis systems. This video demonstrates how to assemble a 2-axis translation system with 2x UMR8.25 stages.
Compatible Actuators
UMR Vacuum stages can achieve 1 µm sensitivity when used with Vacuum BMV6 series differential micrometers. Refer to the specification tables above to see compatible and required adapters for each UMR Vacuum stage.
Designed for Vacuum Applications
Our low outgassing Vacuum compatible linear stages are designed for demanding vacuum environments. Several key steps are taken in the design, assembly and packaging of these parts. Following machining, each component is chemically cleaned in an ultrasonic bath to remove contaminating substances. These stages are double bagged in a cleanroom to ensure contaimation free for vacuum use.
