LOWBOY PRECISION STAGE
• Speed and Precision. LowBoys reach speeds up to
4 m/s with a bi-directional repeatability of ± 1
encoder count.
• Low Profile Design. Even when stacked in a dual-
axis configuration, LowBoys have a stacked height of
169 mm.
• Integration Options. LowBoys can be configured
with an integrated rotary axis. Utilities can exit from
the stage end or base. Top plates can be configured
to customer specifications. Thanks to their self-
contained covers, LowBoys lend themselves to clean
room operation.
• Rugged Construction. LowBoys feature an anod-
ized aluminum and stainless steel construction. Their
linear bearings are lubed for life.
Self-contained, scalable motion modules offer easy integration
