2. Problem Statements Bearing concepts Bearing application areas
The goal of the bearing design:
Satisfy working conditions, load/speed/life requirements.
The factors that a designer must consider when he (she) designs bearings.
Calculation involved in bearing design
How to achieve the design goal ?

4. Requirements:
1. High speed
2. Space

5. Requirements:
1. High loads (shock, unbalance)
2. Long life

6. Requirements:
1. Extremely high load
2. Long life

7. Requirements:
1. Extremely high load
2. Long life
3. Corrosive / Humid ambience

9. Design Problem Input Problem Inputs (known working conditions):
Shaft diameter (d )
Shaft rotation speed ( L )
External loads applied on bearings ( P )
Lubrication condition (grease or oil)
Achieve: Bearing(s)’ design can satisfy user requirements and bearing capacity under certain loads and speed.
