6005 Bearing
Bore (d) 25 mm
Outside diameter (D) 47 mm
Width (B) 12 mm
Inches (bore × OD × width) 0.9843 × 1.8504 × 0.4724″
Deep-groove ball bearing, extra light (6000) series. Seal/shield suffixes (ZZ, 2RS, …) change the closures, never these dimensions — a 6005-ZZ and 6005-2RS are the same size.
What the number means
- 6 — deep-groove ball bearing
- 0 — dimension series (extra light (6000))
- 05 — bore code × 5 = 25 mm
