Impact idler rollers are installed at conveyor loading and transfer points to cushion material impact and protect the belt and support structure. The catalogue uses a steel roller core combined with rubber support rings.
Roller dimensions and ring profiles can be selected according to belt width, impact severity, material size, and support arrangement.
Impact rollers are suitable for conveyor loading zones and can also be used in applications requiring rubber-ring cushioning. The rubber rings are mounted on a steel idler platform to absorb shock and distribute contact pressure.

Available roller inspection and checking methods shown in the catalogue include steel-tube thickness measurement, ultrasonic fault detection, external circular radial runout testing, dust-proof testing, axial displacement testing, waterproof testing, drop testing, and rotating-resistance testing. Steel roller surfaces can be shot blasted before powder coating or baking-paint treatment, depending on the confirmed specification.
Please provide conveyor belt width, roller function, roller diameter, face length, shaft diameter and end style, bearing requirement, troughing angle, bracket arrangement, operating speed, material handled, load, environment, surface treatment, quantity, drawing, or sample. Final dimensions and compatibility are confirmed according to the order drawing.
