Can double shield (ZZ) ball bearings be used in place of single shield (Z) bearings?
I want to replace the bearings on an industrial drill press, and some of the bearings listed are the same size but half are single shield (6206Z) and half are double shield (6206ZZ)
Where I live in Canada it seems to be easier to find the double shield versions
Can I use the ZZ ones in place of Z, or are there instances where a single shield is preferred?
