6207 Bearing
Bore (d) 35 mm
Outside diameter (D) 72 mm
Width (B) 17 mm
Inches (bore × OD × width) 1.3780 × 2.8346 × 0.6693″
Deep-groove ball bearing, light (6200) series. Seal/shield suffixes (ZZ, 2RS, …) change the closures, never these dimensions — a 6207-ZZ and 6207-2RS are the same size.
What the number means
- 6 — deep-groove ball bearing
- 2 — dimension series (light (6200))
- 07 — bore code × 5 = 35 mm
