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 alloys.

C93800 is similar to C93200 but the higher lead content improves the machinability and frictional
properties. C93800 can be used in applications were lubrication may be interrupted without seizing.
Bunting also produces other high-leaded alloys including C93400, C93600, C93700, C93900, C94000,
C94100, C94300, C94400 and C94500.
