Chicago offers two basic types of
cast aluminumwheels. Radial blades
are themost commonly used and
provide the best overall performance.
They consist of either six or eight
blades depending onwheel diameter.
Backward curved blades have
inherently different performance
characteristics, are somewhat quieter,
but are not self-cleaning.
Wheels with tip speeds to 13,000
fpmare cast of 319 aluminumwhile
higher speedwheels are 356 alu-
minumand heat treated. All wheels
utilize an integral straight bore hub
and are statically and dynamically
balanced.
