Maska has been making quality V-belt pulleys, sheaves, bushings, couplings and related mechanical power transmission components since 1964. A Canadian company based in Québec, Maska was bought by Baldor Electric in 2008 to become part of Baldor-Dodge-Reliance. Maska is now one of the top sheave/pulley manufacturers in North America.
Maska sheaves — also referred to simply as pulleys — are generally used with V-belts for power transmission. They can be used for speed and torque ratio changes to increase/decrease shaft speeds as well as increase/decrease shaft torque.
