Solid and cored bars are stocked in 13" increments and 105" lengths, and are available in other
lengths and non-standard sizes. Consider bars for use when you need special bearings, bearings for
prototypes, or for emergency repairs.
Centrifugal cast large diameter cored bars are also available in 13" lengths as well as made to order
sizes and lengths.

C93700 has higher tin and lead than C93200 and is used in bearings with higher speeds and loads. It
has increased corrosion and oxidation resistance, with good anti-frictional properties, good load-carrying
ability and excellent machinability. C93700 can be used in applications where lubrication may be low or
interrupted.
