METALLOGRAPHS | FEATURES AND APPLICATIONS |
| CAST BABBITT |
PB-14 |  |
This lead base Babbitt is soft, excellent embeddability for relative applications, minimum lubrication, good corrosion resistance, good fatigue resistance and has been used for many years in lower load application. |
| PB-15 |  |
This lead base Babbitt has a good bearing performance, good embeddability and has been used for many years in lower load application. | |
| PB-79 |  |
This tin base Babbitt has good load bearing properties and increased wear resistence to high shaft speeds. Has good embeddability and compatibility at pulsating loads. | |
| PB-90 |  |
This tin base Babbitt has good sliding properties, conformability and high toughness, good embeddability 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-7 |  |
Increased hardness and wear resistance. Increasing the lead content improves the tolerance of poor alignment and intermittent lubrication. |
| PB-9 |  |
This material is best suited for bushings and washers subject to high impact and vibratory loads. In most cases, it operates best with hardened shaft. | |
| PB-13 |  |
This material has good antifriction and emergency running characteristics for bearing subject to high surface pressures. | |
| PB-18
PB-21 |
 |
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-23 |  |
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 |  |
This material is best suited for bushings and washers to high impact and vibratory loads. In most cases, it operates best with a hardened shaft. |
| PB-21 |  |
This is a bearing material designed exclusively for high load. The material is plated with a unique trimetal overlay and nickel dam. | |
| PB-23 |  |
This material is employed for bushings and thrust washers applications subject to intermediate impacts and vibratory loads. It has certain degree of embeddability and it is suitable for higher speed and load. | |
| CAST ALUMINIUM (SOLID) |
PBAL-6 |  |
This material having high fatigue strength, good corrosion resistance and conformability is used with hard shafts. |

| The relative ratings for listing alloys and overlays are given for guidance only to allow the user to compare the relevant merits of different materials. The higher the rating number, the better the material. The number given for lining alloys are not related to those given for overlays, nor are the numbers mathematically related. They are merely based on 5 being the best and 1 not good for any particular property. | |||||||||
