NSK's PU/PE series of linear guides provides smooth linear motion in a compact design. Fabricated from martensitic stainless steel, the series features high corrosion resistance and is suitable for miniature applications in the medical, semiconductor and automation industries.NSK equipped the PU/PE series with newly designed resin ball recirculation components that offer smoother motion, reduced noise output and dust generation. The improved design also provides excellent dust proofing, lower particle generation and features a safety design that prevents steel balls from dropping out of the ball slide. Interchangeable rails and ball slides are stocked for quick delivery, and high accuracy preloaded assemblies are also available upon request. The PU/PE series of linear guides come standard with NSK's patented K1™ Lubrication Units, which allow long-term, maintenance-free operation.
