4B74SK

A-B section QD bushed style sheaves provide optimum workspace versatility. QD, which means Quick-Disconnect, helps you to adjust the bore size efficiently and conveniently when opposed to normal bushings. The layout of the A-B segment provides accommodation with various belts such as A, 4L, B and more, ensuring you will actually get a sheave consistent with the appropriate specification. Sheaves in QD (quick detachable) form give a broader range of bore sizes than standard sheaves in the “fixed” type.
