J Frame
A greased-for-life medium duty
Conrad bearing carries thrust
loads developed by the low pres-
sure BP20 series pumps. The
maximum HP motor able to be
mounted on the J frame is the
NEMA 3 HP ODP.
S Frame
Two angular contact bearings
mounted face-to-face carry low to
medium duty thrust loads in this re-
greaseable bearing frame. NEMA
motors from 3 HP TEFC to 25 HP
ODP can be mounted on this bear-
ing frame.
M Frame
A single angular contact bearing carries
medium to heavy thrust loads and provides
oil lubrication for pumps requiring NEMA
motors from 3 HP TEFC to 25 HP OOP.
L and X Frames
The oil lubricated L frame provides high thrust capability as encoun-
tered in high discharge pressure applications with tandem mounting of
angular contact bearings. The L frame takes the same motor sizes as
the Sand M frames. On the X frame, an angular contact, tandem bear-
ing arrangement extends NEMA motor capability from 25 HP TEFC to
40 HP OOP.
Y Frame
Foot mounted industrial NEMA motors
from 40 HP TEFC through 150 HP TEFC
are mounted on the Y frame. The inherent
high thrusts encountered in high pressure
applications are carried by an angular con-
tact tandem bearing arrangement. Pump
mounting is accomplished by utilizing the
motor feet rather than integral mounting
pads on the bearing frame.
