Bearings

Deep groove ball bearings for power tools, machinery, bikes and hobby projects, listed by bearing number and size (inner diameter x outer diameter x width). The bearing number is usually printed on the shield; if not, measure the old bearing in mm.

What do ZZ, Z and 2RS mean?

ZZ (or 2Z) means a metal shield on both sides, Z means one metal shield, and 2RS (or RS) means rubber seals. The numbers are the same bearing size whichever ending you choose.
