Overhung Load Data (Shaft Side Load)
Overhung load data is provided in this
manual for the design engineer concerned
with a specific problem in this area. The
maximum allowable overhung load which
can be applied to the shaft of an Electro-
Module may be determined by the use of
the accompanying chart.

R
The minimum pitch diameter pulley or sprocket
that can be used, for satisfactory bearing life, is
determined from the formula:
Min. P. D. = ––––––
T - Torque, (lbs. in.). This is the torque actually
being transmitted, not necessarily the maximum
torque capacity of the Electro-Module.
Torque = –––––––––––
K - the safety factor for the tension in the type
of drive.
Use:
1 for chain and sprocket
1 for timing belt
2 for V-belt
3 for flat belt
R - Radial load allowable (values at various dis-
tances from the housing face are given in the
chart).

Example: What is the minimum V-belt pulley
that can be applied to the center of the shaft
of an EM-50 module?
The torque requirement is 112 in. lbs.
Min. P. D. = –––––––––– = 2" minimum P. D.
