Features And Applications |
Cast Babbitt
|
Lead Based White Metal |
SAE-14 |
20 |
This lead base Babbitt is soft, excellent
embed ability for relative applications, minimum lubrication, good resistance, low fatigue resistance and has
been used for many years in lower load application. |
| Lead Based White Metal |
SAE-15 |
18 |
This lead base Babbitt has a good bearing
performance, good embed ability and has been used for many years on lower load application. |
| Tin Based White Metal |
SAE-12 |
32 |
This tin base Babbitt has good sliding
properties, conformability and high toughness; good embed ability suitable
for high sliding velocities in the hydrodynamic range, mean load, impact
stress at low frequency insensitive to reversed bending stress. |
Cast Copper
Lead |
Copper Lead |
SAE-793 |
80 |
Increased hardness and wear resistance.
Increasing the lead content improves the tolerance of poor alignment and intermittent lubrication |
| Copper Lead |
SAE-792 |
85 |
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. |
| Copper Lead |
SAE-49 |
60 |
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 |
| Copper Lead |
SAE-794 |
62 |
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
|
Copper Lead |
SAE-792 |
110 |
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. |
| Copper Lead |
SAE-49 |
55 |
This is a bearing material designed
exclusively for high load. The material is plated with a unique Tri metal overlay and nickel dam. |
| Copper Lead |
SAE-794 |
50 |
This material is employed for bushings and
thrust washers applications subjected to intermediate impacts and vibratory loads. It has certain degree
of embed ability and it is suitable for higher speed and load. |
| Clad Aluminium |
Aluminium Tin |
SAE-783 |
40 |
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. |
