The polyamide caged bearing is considered superior for high speed use.

Some people's theory was that the plastic cage would cause no harm to the piston/cylinder.

My experience is that when the cage goes, the rod hits in the bottom of the case when the balls all get on one side and metal gets up on top of the piston anyway.
