OVERHUNG LOAD RATING
PG-136-OH
The magnitude and location of a load is dependent on the following factors:
SF = service factor (Table A)
AF = application factor (Table B)
a = bearing geometry constant = -0.295
T = basic thrust load = 14,500
c = basic load constant = 136,000
L = allowable overhung load in lbs.
y = distance of load centre to mounting face in inches
up to full load occasionally
Intermittent duty at variable loads,
3 hr. day, intermittent duty, full load
8 hr. day, continuous duty, full load
24 hr. day, continuous duty, full load
