Q: What does C3 mean on a 6301 bearing?

Short answer: `C3` on a 6301 means increased radial internal clearance (for heat or interference fits). The boundary dimensions stay 12 × 37 × 12 mm. Suffixes are not interchangeable: the same size with a different suffix behaves differently under load, heat or contamination.
