About the 21300 series
- Against the 22200 series, which shares sixteen bore sizes, the 22200 outside diameter is smaller and the width sometimes larger, sometimes smaller at each shared bore: at d 65 mm the 21313 is 140 × 33 mm and the 22213 is 120 × 31 mm.
- Against the 22300 series, which shares thirteen bore sizes, the 22300 outside diameter is the same and the width larger at each shared bore: at d 70 mm the 21314 is 150 × 35 mm and the 22314 is 150 × 51 mm.
- Catalog dynamic load ratings Cr run from 55 kN (21306) to 425 kN (21319).
- Versions in the 21300 series: W33 on every size, K/W33 on fifteen of sixteen sizes.

21300 series FAQ
Which sizes are in the 21300 series?
ENRO lists sixteen sizes in the 21300 series, from the 21305 (25 × 62 × 17 mm) to the 21320 (100 × 215 × 47 mm). Bore d runs 25–100 mm.
Which versions are listed for the 21300 series?
W33 and K/W33. W33: Groove and holes in the outer ring for relubrication. K/W33: Tapered bore, taper 1:12, for adapter or withdrawal sleeve mounting. Groove and holes in the outer ring for relubrication. Not every size carries every version; the model page lists what is available.
How does the 21300 series differ from the 22200 series at the same bore?
At d 65 mm the 21313 (21300 series) is 140 × 33 mm and the 22213 (22200 series) is 120 × 31 mm: twenty mm less outside diameter and two mm narrower. The two series share sixteen bore sizes; the table above lists each one.
What load ratings are listed for the 21300 series?
Catalog dynamic load rating Cr runs from 55 kN (21306) to 425 kN (21319), with C0r, limiting speeds and weight on each model page. 21305 has catalog values pending confirmation and show “On request”; ENRO does not estimate them.
Where are ENRO bearings made?
ENRO bearings are Made in China by partner factories, under Japan-managed quality control. Every unit passes 100% outgoing inspection before shipment.
