Bearings Products: Metal-Polymer Bearings
Solid bronze, porous bronze sinter, and filled polytetrafluoroethylene (PTFE) make up the three layers of DP4B bearings.
The interpenetrated
sinter and PTFE layers allow
durability while providing coefficients
of friction down to 0.02
when lubricated
with oil.
The bearings
are said to operate
well when
dry or lubricated
with oil, grease, water, or process
fluid. They can handle up to 36-ksi
static load or 20-ksi dynamic
load. Sliding speeds
up to 1,000 fpm are tolerated
when lubricated with
oil. The parts are rated for
a maximum lubricated PV
of 290,000 psi fpm.
DP4B bearings can withstand
temperatures from –200 to 280°C
and operate with minimal corrosion
in saltwater environments.
The lead-free design complies
with end-of-life directives.
