Bearing... Intersection of Movement & Stillness
Babbitt Alloy (Bearing Alloy)
Babbitts (white metals): Composition: In this, there are two types. One is Lead-based Babbitt and the other is Tin-base babbitt. Lead-Base Babbitt: Pb-74%, Sn-10%, Sb-15%, Others-1% Tin-Base Babbitt: Sn-86%, Sb-7%, Cu-6% , Pb-1%, Advantages: They have excellent bondability, embeddability and conformability. They are good corrosion resistant. Limitations: Low compressive and fatigue strength at temperatures above 80 degrees. [...]
Material For Bearing Alloys
Commonly used materials for sliding contact bearings are: Tin Base Babbitt Lead Base Babbitt Lead Bronze Aluminum alloys Silver Lead deposited The various materials are used in practice depending upon the requirement of actual service conditions. The Choice of material for any application must represent a compromise. The Following table shows the comparison of some [...]
Slide Bearing Layers
Layers for Sliding Contact Bearing . According to the number of the main functional bearing layers the bearings may be mono-metal (solid), bi-metal, tri-metal or multi-layer. Most of engine bearings are either bi-metal or tri-metal. Typical bearings layers and structures are presented in below: Steel back supports bearing structure, provides its rigidity and press fit under [...]
Bearing Materials and Their Properties
Bearings plays an important role in the applications where there is rotary motion. They reduce the friction between two mating parts and hence adjacently save the power. For the bearings to be effective, they should have the following desirable properties: Compressive Strength: The max pressure that is acting on the bearing is greater than the [...]
Sliding Bearing Types based on the loads
Sliding Bearings classification based on the type of load carried. a) Journal or Radial bearings In radial bearings, the load acts perpendicular to the direction of motion of the moving element. b) Thrust or axial bearings A thrust bearing is a particular type of rotary rolling-element bearing. Like other bearings, they permit rotation between parts, [...]
Sliding Contact Bearings – Advantages and Disadvantages
These bearings have certain advantages over the rolling contact bearings: 1. The design of the bearing and housing is simple. 2. They occupy less radial space and are more compact. 3. They cost less. 4. The design of shaft is simple. 5. They operate more silently. 6. They have good shock load capacity. 7. They [...]
