Effects of speed, load, temperature and viscosity on eccentricity

Bearing terminologies

Here we discuss :
- Derivation of Petroff's equation
- McKee's equation
- Bearing characteristic number

Bearings #7 : Perltroff's equation

Here we discuss :
-Significance of Sommerfeld number
-mass flow rate of coolant required in journal bearings.

Bearings #8 : Sommerfeld number, coolant required for bearing

Here we discuss :
- Significance of bearing charcot number and bearing modulus
- Viscosity index
- Anti-friction bearing characteristics

Bearings #9 significance is bearing characteristic number

Difference between Journal bearings and anti fiction bearings

Bearings #10 : Design of rolling contact bearings

Designation of anti-friction bearings :
     - SKF Standard
     - Indian standard
- Equivalent load
- Service factor
- Race rotation factor
- Radial load factor
- Axial load factor
- Desired of bearings under fluctuating loads

Bearings #11: Designation of anti-fiction bearings

Here we discuss :
- Life of bearing
- Nominal life 
- reliability of bearings
- Static load capacity
- Basic load capacity
- Average life
