What is the difference between a seal and a shield on ball bearing?

Why can't we just use all seals instead of stocking both shields and seals?

Ans: The shield is attached to the outer race and it is a clearance between the outer and inner race. 

On the other hand the seal is attached to the outer with the inner race. 

The main reasons of not using seals in all applications instead of shields, are: 

1. Speed 2. Heat and 3. Starting Torque 

The seal could cause problems in these areas due to its rubbing against the inner race and in the case of 

shield, there is a clearance between outer and inner race and then there is no such kind of problem.

On single row deep groove type seem to be loose when shaken. Are these bearings loose internally?

Ans: No, everything is fine. The bearing must have a slight amount of movement. This is necessary for running 

clearance, so it does not bind. And say, before for doing this, remember to take a second to wipe off your fingers.
