are bearing codes universal?

[bad_religion_au]

i need to replace one of the bearings in my conversion kit. the part number on it is

KBC 6202z

ive found another manufacturer with a 6202z bearing. are these bearings interchangeable, or just 2 manufacturers with overlapping catalogue numbers?

the 6202 is a standard code, the z and any other prefix or suffix will relate to bearing radii or circlpio grooves ect.

Any bearing shop should be able to match the sample.

KBC will be the brand name.

Where I was working in Brisbane we found out the hard way that not all manufacturers keep the same tolerances.

We had a small bearing which we pressed onto a small dowel for a particular application. Suddenly, we found the bearings were quite rough after being pressed on. Turned out the inner race diameter was under-size - significantly below the tolerance (given what we ordered.) Curiously, some bearings had been supplied in individual sealed plastic sleeves, others were supplied in bulk in a zip-lock bag - it was the zip-lock bag bearings which were undersize. We sent them back to the supplier and asked them to supply the other brand - no more problem.

always use a reputable manufacturer
