6.4 Standard Attachments
Large pitch conveyor chains are usually used with attachments. These attachments are divided into the following categories:
- Industry-specific (Plus α Alpha)
The standard attachments for large pitch conveyor chains are A, K, SA, SK, G, and RFD type. These attachments are available on the following types of chains:
- Treated surface, such as plated chain.
- 304 stainless steel or other special materials.
- Bearing roller or bearing bush specification.
Refer to Applications Section 2.3 for descriptions of these types of attachments:
- A attachment
- K attachment
- SA attachment
- SK attachment
- G attachment
One plate in a pair has bolt holes. These are used to install buckets on two sets of chains (Figure 6.39).

- RFD attachments
The upper side of the link plate is tall; it actually sticks above the R-roller (Figure 6.40). Therefore, conveyed objects can be placed directly on the chain. This is a very economical design.
