1. Features

Expanded range of sprockets to accommodate various conditions

The expanded variety of molded plastic sprockets has enabled to use them in a wide range of conditions.
We have newly lined up 38mm and 51mm square hole sprockets with 18T teeth and 90mm square hole sprocket with 22T teeth.
For WT2520 series sprockets, refer to the sprockets page.

New plug improves maintainability

As of October 2020, new plug has been adopted.
The adoption of a new plug makes it easier to handle and reduces the power required to insert the plug by 60% (compared to our previous plug), making it easier to connect/disconnect the chain.

  • The performance of the new plug (prevention of pin disengagement) is equivalent to that of the old plug.
  • New plugs cannot be used in chains with old plugs.

Stable conveyance with surface contact

Compared to roller conveyors with point-contact conveyance, plastic modular chains convey a variety of stacked sheets in surface contact, enabling stable conveyance without sheet collapse, load collapse, or vibration.

Surface shapes for ease of handling

This chain has a gentle R500 convex shape on its surface.
Stacked heavy sheets slightly fit into the convex shape of each surface to prevent slippage, and they are also easy to move due to their low friction effect when the operator handles relatively lightweight cardboard sheets.

Prevents adhesion of dust and wear powder due to static electricity

The chain material is based on polyacetal resin and is provided with an antistatic function that prevents dust and wear powder from adhering due to static electricity. (Normal specification: Blue only)

  • Volume resistivity：1×1013Ω・cm
Inline layout reduces transfer space.

The backside surface has a rounded shape, which is suitable to wind around the round bar of 50 mm.
It can be minimize dead space between conveyors with round bars at the ends of conveyors in below.

  • Install a safety device (safety cover, etc.) to prevent entanglement.

Improved safety using different appearance color

The operator can check the operation of the conveyor by incorporating links of different appearance color into the main body chain. Contact Tsubaki representative when incorporating links of different appearance colors.

2. Application examples

Although this chain is used mainly in the cardboard industry, its high cost performance has led to the widespread use in other industries.

Suitcase transfer conveyor

Suitcase transfer conveyor

[Process 1]
Transport luggage such as a suitcase.

[Process 2]
Push the transported products to the side with the pusher.

Point：Excellent sliding performance thanks to low-friction properties, enabling smooth extrusion of conveyance objects.

[Process 3]
Transfer to the container using a robot.

Conveyors for machine tools

Conveyors for machine tools1

[Process]
Laser-processed steel sheets are sorted by workers on the conveyor without being loaded on the pallet.

Conveyors for machine tools2

Point：Plastic modular chain prevents scratches on transported products!

Building materials conveyors

Building materials conveyors

[Process]
Materials are stacked and transport to the next process.

Point： Plastic modular chains can transport conveyed products without using pallets. In addition, they can be transported stably without worrying about load collapse or vibrations.
