How to choose a suitable industrial rubber roller?

When selecting industrial rubber rollers, companies should choose suitable rubber materials according to the specific working environment, such as high temperature resistance, wear resistance or chemical resistance. Secondly, consider the main functions of the roller, such as transmission, conveying, pressure application or surface treatment, to determine the required rubber type and hardness.

In addition, evaluate the environmental conditions in which the roller will be used, including temperature, humidity, chemical contact, etc., to ensure that the selected rubber material can work stably for a long time. Then select the appropriate roller size and material according to the mechanical requirements of the equipment, such as load, speed and pressure, to ensure that the roller can withstand the corresponding stress and friction.
