Table E
Axial Thrust Capacity
1
Thrust capacity for vertical mounting includes a constant whose value is plus or minus depending on the direction of the thrust load. The constant is plus for thrust loads
acting upward against the force of gravity and minus for loads acting downward with gravity.
Table F
Radial Load Capacity
1
Data for motors with roller bearings at the drive end (back end). Motors with ball bearings at the drive
end are for coupled duty only.

Contact Allen-Bradley for radial load applications
!
ATTENTION: The use of these radial load capacities
requires the accurate calculation of the radial load for the
application. Radial loads for gears, sprockets, and flywheel
are usually accurately determined but the radial loads due
to V-belt drives are subject to miscalculations because they
do not include all of the pre-tension load (belt tightening).
The calculations of the radial load for a V-belt drive must
include the pre-tension for transmitting the horsepower,
pre-tension for centrifugal force on the belts, pre-tension
for high start torques, rapid acceleration or deceleration,
pre-tension for drives with short arc-of-contact between the
V-belt and sheave, and low coefficient of friction between
belt and sheave caused by moisture, oil or dust. Failure to
observe these precautions could result in damage to or
destruction of the equipment.
