Cast Babbitt |
PB-14 |
SAE-14 |
 |
This
lead base Babbitt is soft, excellent
embedability
for
relative applications,
minimum lubrication,
good resistance,
low fatigue resistance
and
has
been
used
for many years
in lower load application. |
| PB-15 |
SAE-15 |
 |
This
lead base Babbitt has a good bearing
performance,
good embedability and has
been
used
for many years
on lower load
application. |
| PB-90 |
SAE-12 |
 |
This
tin base Babbitt has good sliding properties,
conformability and high toughness; good
embedability suitable for high sliding
velocities in the hydrodynamic range,
mean load, impact stress at low frequency
insensitive to reversed bending stress. |
|
Cast Copper Lead |
PB-8 |
SAE-793 |
 |
Increased
hardness and wear resistance.
Increasing
the lead content improves the tolerance
of poor alignment and intermittent lubrication |
| PB-9 |
SAE-792 |
 |
This
material is best suited for bushings
and washers
subjected to high
impact
and vibratory
loads. In most cases,
it operates best
with hardened shaft. |
| PB-16 |
|
 |
This
material has good antifriction and
emergency
running characteristics for bearing
subject to
high surface pressures |
| PB-18 |
SAE-49 |
 |
High fatigue strength, normally plated
with an overlay when used in bearing
application and in this form may be
operated with hard or soft shafts susceptible
to corrosion by degraded oil when not
overlay plated |
| PB-19 |
| PB-21 |
| PB-23 |
SAE-794 |
 |
High
fatigue strength and shock resistance,
suitable
for high speed shafts, oscillating
or rotating motion
hard shaft desirable,
normally overlay plated when
used in
bearing application. |
|
Sintered Copper Lead |
PB-9 |
SAE-792 |
 |
This material is best suited for bushings and washers subjected to high impact and vibratory loads. In most cases, it operates best with a hardened shaft. |
| PB-21 |
SAE-49 |
 |
This
is a bearing material designed exclusively
for
high
load. The material is plated
with a unique
trimetal
overlay
and nickel
dam. |
| PB-23 |
SAE-794 |
 |
This
material is employed for bushings and
thrust
washers applications subjected
to intermediate
impacts
and vibratory
loads. It has certain degree
of embedability
and it is suitable for
higher speed
and load. |
|
Clad Aluminium |
PBAL-20 |
SAE-783 |
 |
This
has good fatigue resistance, good surface
behavior and excellent corrosion resistance
to with
stand
intermediate to heavy
load of main ,con rod
bearing,
thrust
washer and wrapped bushes for
hard and
soft shafts. |
|
Cast Phosphorus Bronze (Solid) |
PB
PB-101 |
PB2C |
 |
This
material has high corrosion resistance
and wear properties. It is mainly used
in bearing bushings. |
|
Cast Aluminium Bronze (Solid) |
PB
AB-102 |
JIS/HS
114 |
 |
This
material is very hard. Suitable for
structured
components under sliding
conditions and for marine
environment,
hardened shaft, essential,
relatively
poor embedability. |
Cast Aluminum
(Solid) |
PBAL-6 |
SAE-770 |
 |
This
material having high fatigue strength,
good corrosion resistance and conformability
is used with hard shafts. |
