About Impact Beds
Impact beds are installed in the loading zone — the area where material falls from a chute or transfer point onto the moving belt. This is the highest-stress zone in any conveyor system.
Impact bars are the primary load-bearing element of the impact bed. They consist of a UHMW-PE wearing face bonded to a rubber core.
Frequently Asked Questions
Bed length is set by the throw distance of the material stream from the transfer chute, which is a function of drop height, belt speed, and material particle size. As a general rule, the impact zone should extend at least 1.5× the horizontal throw distance beyond the chute outlet. Heavy-duty applications with large lumps or high drop heights require longer beds.
Impact bars have a UHMW-PE wearing face over a rubber shock-absorbing core, designed to absorb kinetic energy from falling material. Slider bars use UHMW-PE throughout without a rubber core — they provide continuous belt support and low-friction sliding contact but offer no shock absorption. Impact bars are used in the high-drop zone; slider bars extend the supported zone beyond it.
UHMW-PE (Ultra-High Molecular Weight Polyethylene) has a very low coefficient of friction against conveyor belt backing rubber — typically 0.05–0.15 — which minimises drag, heat generation, and belt wear. It is also highly resistant to abrasion, impact, and most chemicals, giving long service life in aggressive loading zone environments.
Bar life depends on belt speed, material abrasiveness, and loading rate. In medium-duty applications with moderately abrasive material, impact bars typically last 6–18 months. The bar design allows individual bars to be replaced without removing the frame, reducing downtime. Worn bars should be replaced before the rubber core contacts the belt, which would cause rapid belt damage.
Impact beds are compatible with standard rubber-backed conveyor belts. They should not be used with PVC-backed or fabric-topped belts without verifying friction compatibility. The belt tension must be sufficient to maintain contact with the bars across the full bed width — insufficient tension causes the belt to lift off the bars under impact, reducing protection effectiveness.
Impact beds are mounted to the conveyor stringers using adjustable clamp or bolted brackets. The mounting must be rigid enough to resist the lateral and vertical forces from the material stream without deflection. Adjustable mounting allows the bed to be centred under the chute discharge point and levelled to match the carrying idler line.
