Instead of a hydraulic jack, lightweight operation for load holding! Compact rack jack.
No need for brake stoppers! Self-locking at the stopped position during work elevation! Lighter operability and faster lifting speed than screw types! Ideal for explosion-proof measures!
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 at the stopped position while raising and lowering the workpiece. Additionally, 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 features a standard black Teflon coating that is resistant to rust. It can be widely used for disaster preparedness, energy-saving measures, and defense/military applications. It is also suitable for universities, research institutes, testing facilities, and explosion-proof measures. 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 can resume raising and lowering without any motion delay. It is compatible with commercially available round rack rods (manufactured by KHK). (Rack rods are not included.)

basic information
【Product Lineup】 SLM (Manual Only) Series Available for load capacities of 50/100/200/400 kg Comes with a dedicated handle Commercially available round rack rods (KHK brand) can be used. (Rack rods are not included) Available in T type for guide rods to prevent buckling, and D type for connecting two units in parallel. SLE (Electric Tool Assist) Series Uses commercially available electric drill drivers (Note: impact drivers are not allowed) to raise and lower the workpiece. Similarly, it holds the load at the position where the driver is stopped. Restarting is also possible without motion. The input shaft tip is hexagonal to accommodate commercially available sockets, and it can of course be used manually. *Dedicated handle is optional Available for load capacities of 100/200/400 kg For detailed specifications, please refer to the Ipros product information, our company website, or catalog.

Detailed information
-
Overwhelming advancement! It can raise and lower the rack rod by 11.5 mm in one rotation, and it's compact! Of course, it holds the load when stopped. SLW-100-11.5-20
-
This is a round number linear jack. In the case of SLM-050-4.0, it raises and lowers exactly 4mm per rotation. In the case of SLM-200-3.0, it raises and lowers exactly 3mm per rotation. Due to its compact size, it can be installed in tight spaces. There are many applications, such as simple lifting in places without power.
-
It is also possible to synchronize two racks. By connecting them with a connecting pipe as shown in the image, turning the handle can simultaneously raise and lower the rack rods. It can be designed quite compactly.
-
The lineup also includes models with guide rods. Adopted for experimental equipment in a certain university laboratory. If you are concerned about the buckling of the rack rods, we recommend the twin shaft type.
-
Electric Tool Assist Type SLE Series Compatible with commercially available high-torque electric screwdrivers (impact drivers cannot be used) with a hexagonal tip specification. Enables work in locations without power supply.
-
Adopted by a certain heavy industry manufacturer for defense and military purposes. Due to outdoor use, the entire surface is treated with black chromate. Used in the tilting parts of the equipment. Supports up to 400 kg. Compatible with rack rods of Φ30.

Company information
The load-holding function equipped reduction mechanism (shoji-lock) has been developed for application products such as winches and rack jacks since the early 2000s. Steady sales activities have borne fruit, and it has begun to be adopted for various applications. Unlike conventional worm reduction gears with self-locking functions where the input and output shafts are orthogonal, our design features them in a straight line (inline), allowing for a compact design and space-saving, which has received high praise and resulted in a diverse range of practical examples. (Patents have been obtained in Japan, the United States, the EU (Germany, France, the UK), China, South Korea, and Taiwan.) Furthermore, starting in April 2023, we launched a new overseas parts procurement business, beginning with Vietnam. Currently, a majority of our parts are procured overseas, and leveraging our achievements and network, we aim to assist companies struggling with cost reduction in parts procurement.
