The uni® 821 PRR chain is double hinged with pressure reduction rollers. It has the straight running uni® 821 chain as base chain. The chain is suitable for application where accumulation of long items occurs or for items that should not be damaged by the accumulation pressure.
Rollers with free rotation on their axles are mounted on the upper surface of the chain. The axles for the rollers is supplied in stainless steel. Compared to uni® 821 PRR4 the larger and more rigid axles will support higher product weight without deflection of the axles.

All dimensions are for POM-chains.
