– 30 – BLOCK DIVISION, INC. SHEAVES SHEAVESWITHBUSHINGSORBEARINGS.Block Division’s sheaves are machined from cold rolled bar stock and then bright zinc electroplated for corrosion resistance. We offer our sheaves in a variety of ways to accommodate your needs, including 10 different sizes of sheaves with optional plain bore, oil-impregnated bushings, or general purpose sealed ball bearings. This type of bearing promotes spreading the weight out uniformly along the double seals, which will also protect the bearing in harsh environments. The product matrix below depicts the Sheaves with Bushings. In each one of these products, we can replace the bushings with bearings. The corresponding part number for a sheave with bearing will end with –BRG. For example, to order a 00158 sheave with a bearing instead of a bushing, please also indicate parts number 00158-BRG and ID (shaft size). Have questions? Call Block Division to discuss your bushing or bearing requirements.
