(1) PV limits are shown for unlubricated radial bearing applications.
Low temperature / submerged installation may permit PV limits up
to 2x higher. For high ambient temperatures, calculated PVs must
be reduced.
|
(2) Proper use of exclusionary seals can greatly extend bearing life.
Forsheda V-rings are very effective with any of EDT’s plane bearings.

Block bearings can accommodate only a slight
degree of shaft misalignment. In locations where
misalignment occurs, self-aligning bearing units
should be used.
EDT offers self-aligning housings:
Polymer housings (see
Section D-GREY)
Stainless housings (see
Section E-BLUE)
EDT offers solid polymer spherical bearing inserts:
Poly-Round bearings (see
Section H-WHITE)
HOW TO CALCULATE PV
PV - P x V
P - pressure in PSI (lbs./sq. in.)
V - velocity in SFM (surface ft./min.)
P - F/A
where F = force (load) on bearing
A = shaft dia (in.) x LTB
(LTB = bearing length through the bore)
V - .262 x D x RPM
where D = shaft diameter (in.)
RPM = shaft revolutions/min.

LOCKING SLEEVES
EDT 316 stainless steel locking
sleeves protect shaft surfaces
from abrasion and the normal
wear caused by plane bearings.
Locking sleeves provide:
- Improved journal surface to increase bearing life
- Control of lateral shaft movement (replaces standard locking collar)
- Protection to shaft
- Abrasion resistance
- Repair to damaged shafting
Locking sleeves can run on either side of the solid
polymer block bearing, depending on the space
available.
