MISUMI Telescopic Slide Rail

The MISUMI SAR Series aluminum telescopic rails are designed for compact and precise linear motion applications in robotics, automation systems, and mechanical assemblies. Built from lightweight anodized aluminum alloy and featuring high-durability stainless steel ball bearings (EN 1.4125 equivalent), these rails offer smooth extension and retraction with minimal friction. Available in two-stage (SAR2XX) or three-stage (SAR3XX) configurations, they provide various stroke lengths to suit a wide range of installation scenarios.

Thanks to their low profile and lightweight build, the SAR rails are ideal for space-constrained applications where consistent linear guidance and structural reliability are essential.
