Patented screw blades

The screw blades, patented under patent number 5800013, are manufactured in-house.
We manufacture high-quality, reliable screws made in Japan.

The only company in Japan that handles design and manufacturing (from bending to welding and assembly).

Property-specific solutions and on-site demonstrations of the equipment.

Six advantages we can offer because it's shaftless

1) No adhesion or blockage to the shaft.
2) Capable of transporting on steep inclines (from 0° to 90°)
3) Diverse connections between devices
4) Low rotation speed and rotation on resin liner for low noise
5) Completely airtight, no odors or spills.
6) Long-distance transport with a single unit (32m)

1) No entanglement of transported objects
There is no concern about blockage due to adhesion to the shaft, and debris and pulp are easily transported.
2) Capable of transporting on steep inclines.
It can transport objects at inclines from 0° to 90°. It can also transport objects vertically, making it suitable for installation in confined spaces.
3) A wide variety of combinations are possible
There are no bearings at the end of the conveyor, and there are no restrictions on connecting equipment. The layout is flexible, allowing for vertical, horizontal, and diagonal placement.
4) Low noise
Low rotation speed on the resin liner results in low noise during transport. The transported material acts as a lubricant, reducing wear on the resin liner.
5) Completely sealed
It eliminates problems such as odors and spills of transported materials, and significantly reduces the effort required for daily maintenance and cleaning.
6) Capable of long-distance transport
The cantilevered screw can transport up to 32m with a single unit. It eliminates the need for belt tension adjustments, significantly reducing daily maintenance effort.

1) Designed and manufactured domestically
High-quality Japanese spiral materials are used. Furthermore, design consultations and quotation responses are prompt, and customized solutions are available for each project to meet specific needs. The positions of deodorizing piping and material input/output ports can also be freely laid out.
2) Essentially maintenance-free
Maintenance is performed solely through visual inspection via an access port. Unlike other systems, cumbersome tasks such as checking belt tension and measuring bearing temperature are unnecessary.
3) Claim rate: 0.006%
Shinko Kogyo's shaftless screws are welded one by one at their domestic factory, and the welding is performed by skilled welders, so there is no need to worry about the screws breaking.
4) On-site demonstration using a demo unit
Upon request, we can conduct an on-site demonstration using a 6-meter-long demo unit. You can see the actual equipment in action, from loading to unloading materials, and experience its performance firsthand.
