Aluminum pulleys with ceramic coating.These pulleys, which offer great resistance to wear,
have solved a problem experienced in wire drawing.
The wire travels with extreme facility on the pulley, practically eliminate the
maintenance in this sector.
One of the main advantages of this coating, beside greater resistance to wear, is its high
level of elasticity which prevents its detachment by thermal shocks.
Laboratory tests have proven that heating a Rizzardi Aluminum
Pulley with the ceramic coating to a temperature of 400°C and cooling repeatedly in
water, no coating detachment occured and the characteristics of the coating remain
With this coating, the Rizzardi Pulleys are manufactured in various shapes and
meet customer requirements
