V-belt pulley - Power-Wedge® QD® series
Power-Wedge QD Pulleys are specially designed in order to meet the needs of Power-Wedge with a number of V-Belt hard drives. These kinds of hard drives produce feasible cheaper, lesser weight, plus much more compact hard drives. Simply because push widths are decreased and bearing loads are reduced. Smaller diameter pulleys along with reduced center distances are functional.
