庄司歯車エンジニアリング Product Lineup

We have developed numerous application products equipped with a unique load-holding function (shoji-lock) that 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 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 orthogonal, our design has the input and output shafts aligned in a straight line (in-line), making it significantly 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 sound, making it suitable for use in quiet environments. - It features a basic sealed structure (IP65) and is maintenance-free. - 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 each model, suitable for clean room applications. *For more details, please feel free to contact us.

The compact type of the already well-received "S-Linear Actuator" SLB series has arrived. Compared to the conventional products that docked our self-locking gear reducer (S-Reducer) to the block, this new design incorporates the reduction mechanism within the block itself, achieving a compact design. By transitioning from a two-piece (block + reducer) to an integrated type, we can now offer it at a lower price. The speed of the rack's ascent and descent has also significantly increased to approximately 11.5 mm per rotation. Additionally, by equipping it with guide rods parallel to the rack, the strength against buckling and other issues has increased, expanding its range of applications even further. It moves faster than a screw and maintains self-holding when the rotation stops. *For more details, please visit our official website or feel free to contact us.*
