Q: What does ZZ mean on a 6200 bearing?

Short answer: `ZZ` on a 6200 means metal shield on both sides (non-contact, lower drag, less sealing). The boundary dimensions stay 10 × 30 × 9 mm. Suffixes are not interchangeable: the same size with a different suffix behaves differently under load, heat or contamination.
