What are the dimensions of a 6020 bearing?

Answer 100 × 150 × 24 mm

The 6020 is a deep-groove ball bearing: 100 mm bore, 150 mm outside diameter, 24 mm wide.

How it is worked out

  1. Type6 → deep-groove ball bearing
  2. Series60 → series 60 · extra-light · dimension series 10
  3. Bore code20 → 20 × 5 = 100 mm

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

Worth knowing

In inches
3.937 × 5.906 × 0.945 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 6020-2RSH or -2RS1, FAG 6020-2RSR, NSK 6020DDU, NTN 6020LLU.
ZZ · 2Z · 2ZR
Metal shield on both sides. Less friction and more speed than a seal, but not watertight. SKF 6020-2Z, FAG 6020-2ZR, NSK and NTN 6020ZZ.
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 6020 from any maker fits the same shaft and housing. Seals, cage, clearance and quality are what differ.
