QD bushed sheaves (8V section
) 4-groove have four grooves on the sheaves that can only be fitted with narrower 8V section belts. The QD bushed sheaves offer high transmission power ratings than the same size sheaves using standard V-belts. The multiple grooves reduce the chances of the V-belts slipping. The QD bushed sheaves
(8v-section) 4-groove can produce high transmission power that allows the belt drive to move heavier loads. The sheaves grooves have been deepened by design to accommodate more surface area contact with narrow V-belts
. The narrower 8V section belts produce a wedging action that increases the frictional force, increasing the transmission power of the belt drive. QD bushed sheaves (8v-section) 4-groove can provide more transmission power than sheaves with lesser V-belt cross-sectional dimensions. The Sheaves' durability depends on the material of construction and quality of its QD bushings. It also easy to install and requires minimal maintenance with careful attention given to repairs to avoid using the wrong belts.Purchase the best QD bushed sheaves (8v-section) 4-groove from MRO Supply.
