NSK Linear Guides™ Miniature PU Series/PE Series
Smoother motion
The resin ball recirculation component creates an
optimal configuration, resulting in smoother motion.

Low dust generation
The PU series/PE series, with resin ball recirculation
components, generates less dust than a
conventional ball recirculation system that goes
right through the ball slide.
Test conditions: Grease lubrication (LG2)
Operating speed: 600 mm/min
Stroke: 200 mm
