If you take the number etched on the bearing to an industrial bearing supplier they should be able to match it. Beware however that there is a tacit agreement in the industrial bearing business not to supply bearings for 'automotive application' these are flagged up as possible auto use on their lists,and they will tell you that it is unavailable and suggest an auto supplier. So if they ask what it is for don't say car.Instead, say it's from a ceramic clay process machine, they are unlikely to know what this is (except Stoke on Trent guys).If it comes in a Plummer block pop it out and chuck the block away. Usually about 1/4 of the car shop price this way. Your local SKF stockist is worth a try.
