6012 Bearing

Bore (d) 60 mm

Outside diameter (D) 95 mm

Width (B) 18 mm

Inches (bore × OD × width) 2.3622 × 3.7402 × 0.7087″

Deep-groove ball bearing, extra light (6000) series. Seal/shield suffixes (ZZ, 2RS, …) change the closures, never these dimensions — a 6012-ZZ and 6012-2RS are the same size.

What the number means

6 — deep-groove ball bearing
0 — dimension series (extra light (6000))
12 — bore code × 5 = 60 mm

Neighboring sizes (extra light (6000) series)

Designation	Bore	OD	Width
6010	50 mm	80 mm	16 mm
6011	55 mm	90 mm	18 mm
6012	60 mm	95 mm	18 mm

Same bore, other series

Fits the same 60 mm shaft with a different OD/width envelope and load capacity.

6212 — 60 × 110 × 22 mm (light (6200))
6312 — 60 × 130 × 31 mm (medium (6300))

Common suffixes on a 6012

Suffix	Meaning
ZZ / 2Z	steel shields both sides (metal, non-contact)
Z	steel shield, one side
2RS	contact rubber seals both sides (SKF 2RS1, NSK DDU, NTN LLU)
RS	contact rubber seal, one side
2RZ	low-friction non-contact seals both sides (NSK VV, NTN LLB)
C3	radial internal clearance greater than Normal (common in motors)
C2	radial internal clearance smaller than Normal
NR	snap ring groove in the outer ring, with snap ring
P6 / P5 / P4	ISO precision classes (≈ ABEC 3 / 5 / 7)

Data provenance. ISO 15, Rolling bearings — Radial bearings — Boundary dimensions (general plan) (ISO). Nominal boundary dimensions per ISO 15; shaft/housing fit tolerances are an application decision — consult a bearing catalog's fit tables. See all data sources.
