Q: What does 2RS mean on a 6204 bearing?

Short answer: `2RS` on a 6204 means rubber seal on both sides (contact seal, keeps dust and coolant out). The boundary dimensions stay 20 × 47 × 14 mm. Suffixes are not interchangeable: the same size with a different suffix behaves differently under load, heat or contamination.
