jack Product List and Ranking from 38 Manufacturers, Suppliers and Companies

Rack-type jack for railway applications (without screws) with load retention feature.

No need for brakes or stoppers! You can work or conduct experiments while maintaining the position even when the elevation is stopped. Unlike screws, it offers easy operation along with being lightweight, smart, and compact!

Unlike conventional screw jacks, this rack-type jack features an overwhelmingly fast rise and fall speed due to its high efficiency and lightweight operability. It is equipped with a unique self-locking mechanism that allows it to hold loads without brakes or stoppers, making it a groundbreaking jack. In emergencies, it can operate and hold loads even without a power source. It is available in a manual type with a rated thrust load of 50 kgf. Additionally, it has a large stroke, making it a highly versatile rack jack and linear actuator suitable for railway-related applications, universities, research institutes, and testing facilities. As shown in the photos and videos, when mounted on a lab jack or table lifter, it can hold its position with a load applied, and when the handle is turned again, it resumes rising and falling without any motion delay. (For more details, please refer to our website or catalog.) The basic surface treatment is a black Teflon coating that is resistant to rust. *For more information, please visit our official website or feel free to contact us.*

Lightweight operation compared to screw-type for load retention! Compact rack-type jack for shipbuilding applications.

No need for brake stoppers! Self-locks at the stopped position during work elevation! Lighter operation than screw types, faster lifting speed! Additionally, space-saving!

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. 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 a power tool drill driver. The surface comes standard with a black Teflon coating that is resistant to rust. It can be widely used for disaster prevention and energy-saving measures without a power supply, as well as in defense and military applications. It is also suitable for universities, research institutes, and testing facilities. 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 lifting and lowering without any motion delay. It is compatible with commercially available round rack rods (manufactured by KHK). (Rack rods are not included.)

Widely used in semiconductor devices: Load-holding reducers, winches, and jacks.

Winches, rack jacks, and reducers that self-lock without brakes are widely used in semiconductor devices, with the key factors being lightweight, compact design, and space-saving!

We have developed numerous applied products featuring our unique load-holding function 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 slows down and transmits power, but rotation is not possible from the output side = self-locking function. This means that it can hold the load at the desired position without the need for brakes. - Compared to worm gear reducers with the same self-locking function, it is highly efficient. Additionally, while the worm has the input and output at right angles, our design has the input and output shafts aligned in a straight line (in-line), making it considerably more compact and space-saving, as well as lightweight. - Unlike ratchets or one-way clutches, it can hold the load at any position when motion is stopped, regardless of the direction of rotation. Furthermore, there is no ratchet noise, making it suitable for use in quiet environments. - It features a basic sealed structure (IP65) and is maintenance-free. - We offer a variety of applied products, including reducers 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.

Jack, rack type / no screws used, self-locking electric/manual, 400 kg.

Compared to screw jacks, this is a hybrid type that can be operated with commercially available electric tools due to its high speed and efficiency, and can also be operated manually by attaching a handle.

Unlike conventional screw jacks, this rack-type jack features an overwhelmingly fast rise and fall speed due to its high efficiency, making it easy to operate. Therefore, it can be operated quickly with standard electric tools (drivers/drills). Equipped with a unique self-locking mechanism, this revolutionary jack can hold loads without brakes or stoppers. Additionally, it boasts excellent strength and durability while being lightweight and compact in design. It also employs an omnidirectional actuator that can accommodate upward, downward, and lateral movements. It is ideal for rack-type electric cylinders, with a rated thrust load of 400 kgf and a reduction ratio of 78. *For more details, please visit the official website or feel free to contact us.
