Riveted formed steel cage vs nylon cage w/ spherical seat
(OP)
Will I see much, if any, speed rating advantage with the snap-in nylon cage / spherical seat versus a riveted, formed steel cage. Grease packed running in the mid 20k rpm. 12-14 mm ID. ABEC 1.
Also any ideas on gauging an advantage for same issue with speed by moving to an ABEC 3?
Thoughts or guidance to advice greatly appreciated.

one aspect of speedability is heat production, which is related to the bearing's ABEC rating. But, you must meet the tolerances for nearly a dozen geometric features of the the Bearing seats on the shaft and in the housing for the bearing to perform as planned (hoped). Purchasing a higher ABEC rated bearing will not compensate for out-of-square shoulders etc.

to eliminate cage shake and to keep it on its diameter.
Possibly a cage with an extension to ride on one of the
lands of the bearing might be a solution. At those speeds
is grease really an option?
