Lightweight operation compared to screw-type for load holding! Compact rack jack for water treatment equipment.

No need for brake stoppers! Self-locks at the stopped position during work elevation! Easier to operate than screw types, making it suitable for women! Solves labor shortages and improves productivity!

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 traditional 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 power tool drill drivers. The surface comes standard with a black Teflon coating that is resistant to rust. Its ease of operation allows even women and the elderly to easily raise and lower heavy workpieces, 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 once the handle is turned 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.)

Smooth Screw Jack

Stainless steel screws + engineering plastic gears. Saves space without the need for steel balls or return tubes.

The "Smooth Screw Jack" is a jack composed of a worm gear and a stainless steel screw shaft. It serves as an intermediate option between a small jack and a ball small jack, with a simple structure being its major feature. Since it does not require essential components like steel balls and return tubes for ball screws, it allows for significant space savings. Additionally, it has a self-lubricating action, making it maintenance-free. 【Features】 ■ Basic capacity: 2kN, 5kN ■ Extremely lightweight design while ensuring strength ■ The main body case is compact and can be mounted on either side ■ It is possible to manufacture a stop mechanism to prevent the screw shaft from rotating ■ A wide range of options available, including bellows for screw shaft protection, trunnion bases, limit switches for control, and RC encoders *For more details, please refer to the PDF document or feel free to contact us.

Explosion-proof measures: Load retention without power! Inline reducers, winches, jacks.

Self-locking winches, rack jacks, and reducers require no brakes. Ideal for work in locations without power! Lightweight and compact with multiple applications!

We have developed numerous applied products featuring a unique load-holding function with a reduction mechanism (shoji-lock), which have been well received by our customers. <Features of Shoji-Lock Products> - When rotation is applied from the input side, the output side decelerates and transmits power, but rotation is not possible from the output side = self-locking function. This means that no brake is needed, and loads can be held at the desired position. - Compared to worm reduction gears with the same self-locking function, our products are highly efficient. Additionally, while worms have input and output axes that are orthogonal, our input and output shafts are aligned in a straight line (in-line), making them significantly more compact and space-saving, as well as lightweight. - Unlike ratchets or one-way clutches, loads can be held at any position when motion is stopped, regardless of the direction of rotation. Furthermore, there is no ratchet noise, making them suitable for use in quiet environments. - Basic sealed structure (IP65) for maintenance-free operation. - We offer a variety of applied products, including reduction gears that utilize this self-locking mechanism, winches, and linear actuators (rack jacks). - Stainless steel versions are also available for each model, suitable for clean room applications. *For more details, please feel free to contact us.

Due to its ease of operation, even women and the elderly can easily raise and lower heavy workpieces, 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 once the handle is turned 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.)

Widely adopted in automobile factories: self-locking reducers, winches, and jacks.

Winches, rack jacks, and reducers that hold loads without brakes are widely adopted in automobile factories, with the key factors being lightweight, compact design, and space-saving!

We have developed a number of applied products featuring a unique load-holding function with a deceleration mechanism (shoji-lock), which have been well received by our customers. <Features of shoji-lock products> - When rotation is applied from the input side, the output side decelerates and transmits power, but rotation is not possible from the output side = self-locking function. This means that no brakes are needed, and loads can be held at the desired position. - Compared to worm gear reducers with the same self-locking function, our products are highly efficient. Additionally, while worms have input and output axes that are orthogonal, our input and output shafts are aligned in a straight line (in-line), making them significantly more compact, space-saving, and lightweight. - Unlike ratchets or one-way clutches, loads can be held at any position where motion is stopped, regardless of the direction of rotation. Furthermore, there is no ratchet noise, making them suitable for use in quiet environments. - They feature a basic sealed structure (IP65) and are maintenance-free. - We offer a range of applied products, including gear reducers, winches, and linear actuators (rack jacks), that leverage this self-locking mechanism. - Stainless steel versions are also available for each model, suitable for clean room applications. *For more details, please feel free to contact us.

Lightweight operation compared to screw-type for energy-saving in factories! Compact rack jack.

No need for brake stoppers! Self-locks at the stopped position during work elevation! Easier to operate than screw types, making it suitable for women! Solves labor shortages and increases productivity!

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. Additionally, its lightweight and compact design allows for space-saving, and it has been adopted and well-received in various fields. Unlike traditional 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. Due to its easy operation, it allows even women and the elderly to easily raise and lower heavy workpieces, 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.)
