Technical Data Large size conveyor chain Chain structure and roller types
Large conveyor chains are made to transport customers' goods and are not ISO standard chains but are custom designed by the manufacturer.
Therefore, chain dimensions may differ among chain manufacturers.
Large Size Conveyor Chain Structure
The base chain consists of five parts: pins, bushings, rollers, and inner and outer plates.
The basic structure is the same as the drive chain.
| Features of Large size conveyor chain structure | |
|---|---|
| Roller | ・Three types: R rollers, F rollers, and S/M/N rollers are available. |
| Inner and outer plates | ・Flat shape. |
| Sprocket | ・Requires a special sprocket. |
Roller Types and Features
1. R-roller
The outer diameter of the roller is larger than the height of the link plate.
Tsubaki's most basic, versatile roller type.
It has a large allowable load and low frictional resistance.
2. F-roller
There is a flange on the roller, attached on the T-pin side, that acts as a guide.
Can easily stop lateral motion. Ideal for regular slat conveyance. When using K attachments, be aware that attachment area may contact roller flange.
3. S, M, N-roller
Sprockets alleviate impact and wear when engaging the chain. They have higher running resistance than R and F Rollers, allowing them to suffer less wear.
- S：Roller outer diameter is smaller than the plate width
- M：Roller outer diameter is slightly larger than with S rollers
- N：Same roller outer diameter as M rollers, with larger pin diameters for added strength
