Schaefer's Blocks rely on a variety of sheaves designs and scorings. Schaefer
sheaves are design to be compatible with Schaefer products. There is
a risk of incompatibility or failure when using Schaefer sheaves in blocks
manufactued by anyone other than Schaefer Marine. The Schaefer
Aluminum UC Sheave with Torlon Ball Bearings are an extremely
low friction ball bearing sheaves that accommodate both line and wire.
High strength self-contained Delrin™ bearing package, and Nomex™/Teflon™ self-lubricated
bushing is used in all "UC" sheaves . The combined benefits
of the design mean easier turning under the heaviest loads.
