[Case Study] Stainless Steel Shaft specification for Air Index Cylinder

[Case Study] Stainless Steel Shaft specification for Air Index Cylinder

An example of changing the shaft material to stainless steel to improve durability in a water environment.

We would like to introduce a case study involving the air index cylinder "MDF series" that we handle. In environments such as cleaning processes in food processing lines, equipment installed outdoors, or low-temperature environments where condensation frequently occurs, there have been cases where rust develops on the shafts (material: iron) used in the standard specification of MDF. By changing the shaft material from standard iron to stainless steel, the MDF was able to operate without compromising its performance and reliability, even in environments where water is present. [Case Overview] ■ Challenges - Rust was developing on the shaft (material: iron) in water-prone environments. ■ Effects and Benefits - Rust formation on the shaft was dramatically suppressed. - Deterioration of the shaft surface was prevented, ensuring smooth operation at all times. *For more details, please feel free to contact us.

Small high-output planetary gearbox SDP31 series with ceramic carrier pins.

Small high-output planetary gearbox SDP31 series with ceramic carrier pins.

[New Product] Achieved high torque support of 2.5N·m equivalent to a 60-square reduction gear in a small size of Φ31!

The SDP31 has a long track record of use in residential equipment and automotive devices. This time, by using ceramic in the pillar section of the planetary gearbox, we have significantly improved torque and reliability. It is now possible to achieve equivalent torque with about 1/4 the volume of a 60-square gearbox, which can assist in the miniaturization and space-saving considerations of your products. With this significant increase in performance and reliability, it is now possible to use it in industrial equipment and other applications. Additionally, by combining it with a brushless motor, it is possible to fully utilize the motor's performance. 【Features】 Compact and space-saving: Achieves high torque equivalent to a 60-square gearbox with about 1/4 the volume. Long lifespan: Passes a 3000-hour durability test using ceramic carrier pins. High torque: Capable of continuous use with a high torque of 2.5N·m, which is 2.5 times that of the conventional SDP31. *For more details, please download the PDF or contact us.
