How it is worked out

  1. Type6 → deep-groove ball bearing
  2. Series63 → series 63 · medium · dimension series 03
  3. Bore code13 → 13 × 5 = 65 mm

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

Worth knowing

In inches
2.559 × 5.512 × 1.299 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 6313-2RSH or -2RS1, FAG 6313-2RSR, NSK 6313DDU, NTN 6313LLU.
ZZ · 2Z · 2ZR
Metal shield on both sides. Less friction and more speed than a seal, but not watertight. SKF 6313-2Z, FAG 6313-2ZR, NSK and NTN 6313ZZ.
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 6313 from any maker fits the same shaft and housing. Seals, cage, clearance and quality are what differ.
