Locate the Input RPM and Output RPM
columns
on the left side of the table. Scroll
down the Input RPM column to locate a listing
where the desired input speed corresponds to
the output speed required in your application.
(Input RPM listings are rounded to the nearest
hundred. Your actual input speed of 1750 can
be correlated to 1800 with no material change
in performance.)
5
Identify the model number
and catalog number
of the
basic reducer by continuing
to the right. See page 19 for
detailed information on building
an exact model number.
6
Verify physical dimensions
using the dimensional drawings
shown on pages 62-121.
3
Move across the table to the Input
HP column
until you find a rating that
is equal to or greater than the actual
input horsepower required. Once
located, check the top of the table to
identify the correct gear reducer size
(818, 821, 824, etc.).
