These are fixed widths, not a continuous width increment.
CHECK BEFORE ORDERING
Check dimensions. Match the parts.
Share belt or chain photos (both sides), sprocket and interface photos, key dimensions, conveyed product details, operating conditions and special requirements.
Check FitSprockets & matching parts
Share sprocket photos, tooth count, shaft bore dimensions and equipment interfaces.
Matching pitch alone does not establish sprocket compatibility.Product & operating conditions
Provide product size and weight, line speed, transfer gaps, temperature and cleaning conditions.
Confirm the configuration for the actual process before ordering.PRODUCT QUESTIONS
FAQ
More answers about product selection, installation and maintenance.
Can this double-hinge chain be used on a curved route?
It is a straight-running chain. The double-hinge design does not make it side-flexing; use a chain and track intended for horizontal curves when the conveyor route turns.
Can I order any width between the listed sizes?
The listed widths are discrete chain sizes, rather than a continuous width increment. Select a listed width for the product base and lane arrangement, then check the matching support track.
Does the double hinge make it interchangeable with a single-hinge chain?
No. A shared pitch does not establish a match for the hinge, underside, drive pockets or supporting track. Compare those interfaces before retaining the existing conveyor components.
Why is the chain weight shown as several values?
Each reference weight belongs to one of the listed carrying widths. Use the value for the ordered width when assessing the moving chain mass; do not average the values or apply one value to every width.
