庄司歯車エンジニアリング Product Lineup

This is a compact and lightweight rack-type jack (linear actuator) equipped with our company's self-locking mechanism (Shoji-Lock). It holds the load in place while raising and lowering the workpiece. Furthermore, it can be restarted from any position without releasing the brake, whether in the upward or downward direction. Due to its lightweight and compact design, it saves space and has been adopted and well-received in various fields. Unlike conventional screw jacks, the rack type offers overwhelmingly faster ascent and descent speeds, characterized by its high efficiency and ease of operation. In addition to the manual-only (SLM series) models, there are also electric models (SLE series) that can be driven by a power tool drill driver. The surface comes standard with a black Teflon coating that is resistant to rust. Thanks to its easy operation, even heavy workpieces can be raised and lowered easily by women and the elderly, contributing to alleviating labor shortages and improving productivity. As shown in the photos and videos, when mounted on a lab jack or table lifter, it can hold its position while loaded, and by turning the handle again, it resumes raising and lowering without any motion delay. It is compatible with commercially available round rack rods (manufactured by KHK). (Rack rods are not included.)
