This bearing fits some standard size JR servos to make them into ball bearing. No sheilds or seals. I've lost the data so I can't tell you which JR model servos this fits. I do provide the measurments. Remove your bushing to measure and see if it will work. This will not fit Futaba 3003 servos as the bearing is slightly larger od. If anybody provides the data, I'll be happy to post it here. SKU Number: RRCBB10x6x245
