How To Use
Maximum Rating Tables
Cast Iron Inline Maximum Rating Tables are
shown on pages 418-431. Selection of the
appropriate gear reducer can be made using
these tables or the Quick Selections on pages
380-416.
BEFORE YOU START:
Identify the Service Factor of the application.
Determine the actual input horsepower of the
PRWRU E\ PXOWLSO\LQJ WKH PRWRU·V QDPHSODWH
horsepower by the Service Factor.
Determine the output speed (RPM) required at
output shaft of reducer.
Identify the mounting style required by your
application from the style charts shown on pages
1RWH WKH GLIIHUHQW EDVHV DQG ÁDQJHV WR
interchange with various competitive units.
To select the proper gear reducer size, use the
Maximum Rating Tables as shown:
3
Move across the table to the Input
HP column
XQWLO \RX ÀQG D UDWLQJ WKDW
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
(717, 727, 747, 757, etc.).
4
Check load capacities
against the needs of your
application. Do not exceed the overhung load (OHL)
capacity shown in the table. Detailed instructions
for calculating the actual overhung load are shown
on page 645. If overhung and thrust loads will be
applied simultaneously or if the load exceeds listed
capacities, contact Factory.
7
Verify physical dimensions
using the dimensional drawings
shown on pages 432-443.
8
Determine reducer mounting
position
from page 467.
6
Identify the catalog number
of the reducer
by continuing to the right. See page 377 for
detailed information on building an exact
catalog number on LeCentric sizes, the
;; VXIÀ[ ZLOO EH UHSODFHG ZLWK RSWLRQDO
Mod-Squad codes as detailed on page 377.
5
Select motor frame size
if reducer is to have a
motorized input.
1
Find the appropriate Maximum Rating
Tables pages
for your basic mounting style.
The tables begin on page 418.
2
Locate output RPM
column on left side
of the table. All ratings are based on an
input speed of 1750 RPM. Scroll down
to the output speed (RPM) required.
Most output speeds are rounded to the
nearest whole number. For exact output
speed, divide 1750 by the ratio listed.
