Keep Each Chain Family's Tooth Form Separate
Similar pitch or outside diameter does not establish interchangeability between different chain designs.
Choose the Sprocket for the Chain's Engagement Geometry
Each chain family has a particular contact geometry at the sprocket. Flat-top, flexible, case and top-plate chains should therefore be identified by their actual references when selecting a drive or idler component.
Machined and moulded options address different sprocket configurations. One-piece and split bodies also require different assembly arrangements. Confirm these choices with the shaft layout and available installation access. The CC600 data below describe a specific case-chain subset of the range.

Resolve Drive and Idler Requirements
Provide the chain reference and tooth count, then show the sprocket bore, keyway or bearing seat required by the mounting arrangement. Identify whether the component transmits torque or turns as an idler.
Check axial space and the body construction against the installation sequence. For several sprockets on one shaft, establish their positions relative to the chain paths and the shaft-retention details.
Match the Drive Component During Chain Replacement
A change of chain family can require a different tooth form even when the conveyor frame and shaft remain. Check the sprocket contact geometry during that change rather than treating the existing outside diameter as a universal reference.
In a case-chain conveyor, the selected sprocket guides the chain around the end shaft. Its diameter affects the end envelope, while the hub and bore determine its position on the shaft. Review both when renewing the drive or return assembly.
Specify Your Chain Sprocket
Send the exact chain reference, tooth count, bore and quantity. Include drive or idler duty, shaft details and the preferred machined or moulded, split or one-piece construction.
