Impact idlers are specifically engineered to absorb shock and minimize damage at conveyor loading zones, where bulk material first makes contact with the belt. Their heavy‑duty rubber rings cushion the impact, reducing stress on both the belt and the supporting structure, ultimately extending equipment lifespan. By maintaining belt alignment and dissipating energy effectively, impact idlers improve overall system reliability and reduce maintenance downtime. They are an essential component in high‑impact areas across mining, aggregates, and material‑handling operations. Please note that the face length on impact rollers varies depending on the number of rubber discs. The gauge length remains in accordance with the SANS 1313 specification.
