Alterations
Selection Process/Points
| Item | Gravity Conveyor Specifications | ||
|---|---|---|---|
| Roller Pitch | Hard Material | 4 rollers support the conveyed object. | |
| Roller pitch ≈ Length of conveyed object (L)/5 | |||
| Soft Material | 6 rollers support the conveyed object. | ||
| Roller pitch ≈ Length of conveyed object (L)/7 | |||
| Roller Dia.*1 | Hard Material | Load capacity that supports the weight of conveyed objects with 2 rollers | |
| R = weight of conveyed object/2 | |||
| Soft Material | Load capacity that supports the weight of conveyed objects with 6 rollers | ||
| R = weight of conveyed object/6 | |||
| Roller Material | Choose from plastic material or metal. The applied load differs depending on the material. Metal materials have a higher load application. | ||
| Roller Length*2 | Roller length can be specified by frame size. If the roller material is metal, the frame size can be specified as 1,000 mm or less; if it is plastic, it can be specified as 1,300 mm or less. Use it at a pitch of 100 mm. | ||
| Notes * 1 Select the roller diameter so that the load R per roller is less than the supporting load, which varies depending on the roller diameter. Determine the supporting load based on the dynamic load rating of the bearing used in the roller shown in the catalog, taking into account the service life. * 2 The roller length is the length perpendicular to the roller width |
