Q: What does 2RS mean on a 6302 bearing?

Short answer: `2RS` on a 6302 means rubber seal on both sides (contact seal, keeps dust and coolant out). The boundary dimensions stay 15 × 42 × 13 mm. Suffixes are not interchangeable: the same size with a different suffix behaves differently under load, heat or contamination.
