  Pulley - Wikipedia, the free encyclopedia
A pulley is a wheel with a groove along its edge, for holding a rope or cable.
Pulleys are usually used in sets designed to reduce the amount of force needed to lift a load.
The basic building block of a pulley, the wheel, was unknown to cultures in the western hemisphere, sub-Saharan Africa and Australia until relatively recent encounters with Eurasians.

 Pulley Maintenance Primer
Lagging is used to increase the traction or griping capacity of drive pulleys to the conveyor belt.
A pulley applied with tensions greater than intended leads to more stress in the end disc and rim and, in turn, decreases the life of the pulley through the limitation of cycles allowed from fatigue limits of the steel and welds.
For problematic pulleys with reoccurring end disc failures it may be necessary to increase the shaft size of the pulley at the hub to minimize deflection and bending stresses within the end disc.

The members of Pulley spent more time together in the studio crafting their third album than any of their previous records, and it shows -- Pulley is their tightest, hardest-hitting album yet.
