- •
Forces to hold constant whirl radius and speed are studied by dynamic simulations.
- •
The constant whirl radius significantly depends on the ball-cage pocket contact force.
- •
Ball-cage pocket contact force is the main driving force for a cage to whirl ahead.
- •
Unequal ball spacing is an important characteristic for stable whirl.
- •
Cage instability occurs under severe skidding conditions.
