① No power required, low cost

This is the lowest cost conveyor that does not require power.It can be used in a variety of ways depending on the application and working conditions, such as manual transport in horizontal installation or gravity transport in inclined installation.

② Wide variety

In addition to differences in materials such as iron, aluminum, stainless steel, and resin, the lineup includes 43 models, ranging from light load small items to extra heavy loads.With a wide range of options, you can choose the perfect model for a variety of transported items.

3. RoHS2 compliant for environmental friendliness

This conveyor is environmentally friendly, using materials that comply with the RoHS2 Directive, eliminating specific hazardous substances from the powder-coated frame, rollers, and bolts.
*Conveyors are exempt from RoHS2, but we are working to comply with RoHS2 in the event that they are used in conjunction with applicable products (electrical and electronic equipment) such as sensors.

① Checking the transported items and working environment

When selecting Roller Conveyor, please first confirm the following prerequisite conditions in as much detail as possible.

② Roller width selection

First, select the roller width according to the external dimensions of the transported item.

① Select the RW nominal roller width to be at least the width of the bottom of the transported item + 50 mm.

② If there is a curve, the roller width will vary depending on the width and length of the transported item. Refer to the table below to select the roller width.

③ Even if the width of the bottom of the transported item is wider than the roller width, it can be transported if the bottom is flat and not sagging (overhang transport). However, the bottom of the transported item must not come into contact with the conveyor frame. The roller width should be 70 to 80% of the width of the bottom of the transported item.

When transporting pallets, etc.

Considering the strength of pallets and the transportation of heavy items, we recommend using a double-row conveyor.

③ Model selection

The impact load on the rollers varies depending on the loading conditions and work method.
Select a roller that can withstand impacts using the values below and the strength table for each roller.
Strength of one roller ≧ Maximum amount of material being conveyed × Impact factor (N)

④ Roller pitch selection

Always make sure that the bottom of the transported item is supported by at least three or four rollers. Also, make sure that the load received by each roller is below the allowable load.

⑤ Selecting the frame and leg mounting pitch

As a guideline, one leg should be installed every 1,500 to 2,000 mm on straight sections. As a guideline, one leg should be installed in the middle of curved sections with an angle of 45° or more. For details, refer to the "Strength table for two frames" below, convert the weight of the transported material into mass per 1 m, and select leg installation that is equal to or less than the allowable load.

⑥ Guide to selecting the self-propelled gradient (incline angle)

The self-propelled gradient will vary depending on the condition of the bottom surface of the transported object, the material, and the weight, but please refer to the table below as a rough guide.

*If the bottom surface is made of a soft material such as cardboard, a large amount of material will get stuck in the rollers, causing increased resistance.

Roller only

The PS, LS, SRS, and NTS types use greased bearings that are also used for the drive, so rotational resistance is somewhat greater.
