How it is worked out

  1. Type6 → deep-groove ball bearing
  2. Series62 → series 62 · light · dimension series 02
  3. Bore code12 → 12 × 5 = 60 mm

d = bore code × 5 mm (04+) · 00 = 10 · 01 = 12 · 02 = 15 · 03 = 17 mm

Worth knowing

In inches
2.362 × 4.331 × 0.866 in. A metric bearing: inch-series bearings (R8, 1600…) do not fit the same shaft.
2RS · 2RS1 · 2RSH · DDU · LLU
Rubber seal on both sides, greased for life. Best against dirt and water, slightly more drag. The same bearing by brand: SKF 6212-2RSH or -2RS1, FAG 6212-2RSR, NSK 6212DDU, NTN 6212LLU.
ZZ · 2Z · 2ZR
Metal shield on both sides. Less friction and more speed than a seal, but not watertight. SKF 6212-2Z, FAG 6212-2ZR, NSK and NTN 6212ZZ.
RS · Z
Seal (RS) or shield (Z) on one side only, the other side open: for bearings fed oil or grease by the machine.
C3
Internal clearance larger than normal. Standard on electric motors and wherever the shaft runs hot or the fit is tight. Replace a C3 with a C3.
Interchangeable?
Yes. ISO 15 fixes the bore, outside diameter and width, so a 6212 from any maker fits the same shaft and housing. Seals, cage, clearance and quality are what differ.
