5. Free Flow Chains
5.2.3Outboard Roller Chain—Top Roller Type Free Flow Chain: Automotive industry, precision equipment industry, general uses Application Example Outboard Roller Chain with Top Rollers (Top Roller Chain) is used primarily in the automotive and precision equipment industries for free flow conveyance (Figure 5.12). Construction and Features Top Roller Chain is based on the standard chain with extended side plates (SK-1 attachments). Top rollers are installed on the pins that connect SK-1 extended plates. Pallets with conveyed objects are loaded on the top rollers. Table 5.4 shows some of the base chains that are available.
