6010 Bearing
Bore (d) 50 mm
Outside diameter (D) 80 mm
Width (B) 16 mm
Inches (bore × OD × width) 1.9685 × 3.1496 × 0.6299″
Deep-groove ball bearing, extra light (6000) series. Seal/shield suffixes (ZZ, 2RS, …) change the closures, never these dimensions — a 6010-ZZ and 6010-2RS are the same size.
What the number means
- 6 — deep-groove ball bearing
- 0 — dimension series (extra light (6000))
- 10 — bore code × 5 = 50 mm
