庄司歯車エンジニアリング Product Lineup

We have developed and adopted numerous application products equipped with a unique load-holding function (Shoji-lock). <Shoji-lock Product Features> - When rotation is applied from the input side, the output side decelerates and transmits power, but rotation is not possible from the output side, which means it has a self-locking function. In other words, 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 input and output axes that are perpendicular, our design features input and output shafts that are in a straight line (inline), making it considerably compact, space-saving, and 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 has a basic sealed structure (equivalent to IP65), is maintenance-free, and is suitable for explosion-proof areas. - We offer a variety of application products, including gear reducers that utilize this self-locking mechanism, winches, and linear actuators (rack jacks). - Stainless steel versions are also available for cleanroom applications across various models. - There are cases where a switch from small hydraulic jacks is being considered.

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.

We have developed numerous applied products equipped with a unique load-holding function (Shoji-lock) that have received positive feedback from our customers. (Patents obtained both domestically and internationally) <Shoji-lock Product Features> - 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 it can hold a 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 input and output axes that are perpendicular to each other, our design has the input and output shafts aligned in a straight line (in-line), making it quite compact and allowing for space-saving and weight reduction. - Unlike ratchets or one-way clutches, it can hold a 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 gear reducers that utilize this self-locking mechanism, winches, and linear actuators (rack jacks). *For more details, please visit our official website or feel free to contact us.
