BRINELL HARDNESS

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.
