庄司歯車エンジニアリング Product Lineup

Are you facing any of these issues with parts procurement? "The local factory I used to rely on for cheap orders has gone out of business... When I got a quote from another company, they offered me a price more than double." "I was sourcing parts from China to reduce costs, but... rising labor costs have eliminated any cost advantages." All of these issues can be resolved through parts procurement in Vietnam and other Southeast Asian regions. Our small-scale manufacturing company has also struggled for many years with reducing parts procurement costs and has faced difficulties in making profits. As a solution, we started working with a Vietnamese company. There were no issues with quality, cost, or delivery time, and above all, we felt a strong sense of "motivation," "positivity," and "integrity," which led us to request various parts from them. Now, we have switched about 60% of our total parts procurement to Vietnam and other overseas sources. We hope to leverage this experience and network to assist other companies facing similar challenges.

• Gearbox

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.)

• Actuator

This is a compact and lightweight winch equipped with our self-locking mechanism (Shoji-Lock). It holds the load at the position where the workpiece is lifted. Additionally, it can be restarted from any position without releasing the brake, regardless of the forward or reverse rotation. Its lightweight and compact design allows for space-saving, making it widely adopted and well-received in various fields. In addition to the manual-only (SWM series) models, we also offer electric tool drill driver-compatible (SWE series) models. The load capacity ranges from 50 kg to 300 kg. Furthermore, we have stainless steel models suitable for clean rooms and vacuum equipment, as well as aluminum models that achieve further weight reduction in some variants. These winches can be widely used for work in locations without power, disaster response, energy-saving measures, defense and military applications, and explosion-proof measures. Since it is not a ratchet, it operates very quietly, making it suitable for nighttime work and environments such as hospitals, research institutes, and laboratories. The stainless steel models are not only used in clean rooms but also have numerous applications in marine and ship-related fields. The aluminum models are very convenient for portability due to their lightweight design. They are also adopted in defense and military-related applications.

• Gearbox

This is a compact inline reduction gear equipped with our company's self-locking mechanism (Shoji-Lock). For example, it can hold a load even if the movement is stopped during the ascent, rotation, or tilting of the device, making it suitable for requests such as wanting to conduct experiments or perform tasks at a stopped position. Another feature is that while conventional worm reduction gears with self-locking functions require a considerable amount of space due to the input and output shafts being orthogonal, our design has the input and output shafts aligned in a straight line (inline), allowing for a lightweight, smart, and compact design that is easy to integrate into various devices. The lineup can be selected based on output shaft torque and reduction ratios, with options available for output shaft torque ranging from 5 to 100 kgm (load × torque arm). Some products are also available in all stainless steel for clean room and vacuum equipment compatibility. The basic model is coated with black Teflon, which is resistant to rust. Additionally, it can operate and maintain load even without power during emergencies. It is being introduced as a mechanical component in various fields, including defense and military applications, plant-related industries, semiconductor manufacturing equipment, automotive assembly lines, and device lid opening and closing mechanisms.

They can be widely used in places without power, for disaster prevention, energy-saving measures, defense and military applications, and explosion-proof measures. Since it is not a ratchet, it operates very quietly, making it suitable for nighttime work and environments such as hospitals, research facilities, and laboratories. The stainless steel models are not only used in clean rooms but are also widely adopted in marine and ship-related applications. Additionally, the aluminum models are very convenient for portability due to their lightweight. They are rated IP65 and have been adopted in medical devices, food machinery, and defense and military applications. With easy operability and a safety structure that does not require a brake, it allows for simple operation by women and the elderly, helping to alleviate labor shortages.

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. Furthermore, it can be restarted from any position without releasing the brake, whether in forward or reverse rotation (for raising or lowering). Additionally, 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 design allows for 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 tools like drill drivers. 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, testing facilities, and explosion-proof measures. Recently, more customers have been considering it as an alternative to small hydraulic jacks, taking environmental issues into account. It is compatible with commercially available round rack rods (manufactured by KHK). (Rack rods are not included.)
