< Weartech Rollers after 12 months of operation.
Due to the high failure rate caused by extremely high-wear and high-tension in the areas of the conveyor belt, the client chose to replace the steel rollers with PVC rollers in order to reduce the risk of damage to the belt. The decision to do so however, came at the cost – a lower roller life of 6 to 8 weeks, due to the poor wear properties of PVC.
Tribotech proposed that the client trial Weartech, which offers the weight and belt-friendly properties of plastic rollers while significantly outlasting the life of steel rollers.
It is projected the Weartech rollers will outlast conventional steel rollers by a factor of 7.
