822 PRRS Roller Top Chain
822 PRRS supports packaged products on POM roller rows fitted above a straight-running chain. Choose the width against the product's actual contact footprint and the installed support track.

Matching plate width alone does not establish fit with the existing drive and track.
A Rolling Surface for a Straight Product Lane
The top rollers separate the product contact from the movement of the chain beneath it. This is useful when a pack pauses while the conveyor keeps running, provided its base rests on enough rollers.
822 PRRS has the same nominal plate-width choices across three sizes. The shape and depth beneath the rollers still matter when replacing a chain: track support, sprocket engagement and carrying height need comparison with the actual assembly.

Keep the Pack Level Through the Handoff
Measure the smallest product base against the roller span. A recessed base or flexible wrapping can contact the roller pattern unevenly.
Check the reverse bend against the return route and compare roller-top height at entry and discharge. Avoid sizing the transfer from the plate surface beneath the rollers.
Buffering Between Packaging Operations
A queue ahead of a wrapping or downstream handling station places products in repeated stop-and-release cycles. The roller surface permits relative movement beneath a stopped pack.
Guide pressure and pack stiffness affect how that queue behaves. A flexible package may sag between contact points, so checking the actual base on the roller pattern is part of evaluating the accumulation section.
Specify an 822 PRRS Chain
Send the width reference, required chain length and quantity. Include a track section and product-base details so CSTRANS can compare roller contact, drive fit and transfer height.
