What are the dimensions of a 6210 bearing?

Answer 50 × 90 × 20 mm

The 6210 is a deep-groove ball bearing: 50 mm bore, 90 mm outside diameter, 20 mm wide.

How it is worked out

  1. Type6 → deep-groove ball bearing
  2. Series62 → series 62 · light · dimension series 02
  3. Bore code10 → 10 × 5 = 50 mm

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

Worth knowing

In inches
1.969 × 3.543 × 0.787 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 6210-2RSH or -2RS1, FAG 6210-2RSR, NSK 6210DDU, NTN 6210LLU.
ZZ · 2Z · 2ZR
Metal shield on both sides. Less friction and more speed than a seal, but not watertight. SKF 6210-2Z, FAG 6210-2ZR, NSK and NTN 6210ZZ.
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 6210 from any maker fits the same shaft and housing. Seals, cage, clearance and quality are what differ.
