The variable number of screws parts allows the optimal length to be achieved saving installation time. As the conveyed volume is kept at almost proportional to the screw-rotation, a precise and stable transport volume can be achieved. Moreover, due to the hermetic structure of the screw there is no possibility of dust contamination from outside.

Carrying rice, wheat, various powder, feed, beans, silica and other bulk materials


Due to its lightweight Proside* reduces the load on the motor (Nylon specific gravity: 1.14, whereas that of iron is 7.85)

Hygienic and economical

Just like a stainless steel, it is free from rust formation, but being much cheaper.

Easy Fitting and assembly time-saving efficiency

By varying the number of screw parts the optimal length can be achieved saving installation time. Moreover, as there is no need for welding or sanding as with metal, assembly time is reduced.
Resistance Features
Proside* has high abrasion-resistance properties.

Chemicals Resistance
Proside* demonstrates stable resistance characteristics to various chemicals and is not affected by weak acids and alkali ※however, acidic substances should not be used.

It may withstand high temperatures up to 60 C, with the heat resistant types withstand temperatures up to 100 C.
※Cold-resistant type (possible lowest temperature -20C) and antistatic models can be made upon request.
Other optional processing to be implemented upon request:
Screw blade cutting
outer diameter.
