Conveyor belts with a low coefficient of friction

The fabric used in Nitta's curved conveyor belts reduces the coefficient of friction to 0.14 (coefficient of friction µ of backside on aluminum). This makes these types of conveyor belts particularly suitable for other applications. Not only will it be a solution for friction critical applications but also for applications where energy (drive) costs need to be reduced.

Forces at Work Conveyor Belts

The force that allows conveyor belts to work so well is, primarily, friction. Friction is defined as 'the resistance that one surface or object encounters while moving over another', or as 'the action of one surface or object rubbing against another.' The ease with which the conveyor belt moves depends on the coefficient of friction, which is 'the ratio of the force that maintains contact
