4.2.3 Selection of Chain Type and Specification
A conveyor design can use a variety of chains, depending on the type of operation, conditions, and material conveyed. Here we present a few points of notice about selection.
- Consider RF, RS, or TP chain first. Typical applications are outlined in Table 4.4.
- If there are no special temperature or environment concerns, and if the chain is not subject to rough usage, you can use plastic roller or RF-B chain. This reduces the amount of friction.
- When you require accurate stopping location or must avoid chain elongation, select RFN.
- NF is suitable for rough use and for conveyance of high-temperature objects.
