N1013 K is a cylindrical roller designation documented on BearingIndex from 1 manufacturer publication. The published boundary dimensions are 65 × 100 × 18 mm. The designation ends in bore code 13, which resolves to a 65 mm bore under ISO 15 and matches what the manufacturers published. Every value below comes from that manufacturer’s own published material, with the date it was recorded.
A dash means that manufacturer did not publish the value. Dimensions every source agrees on are shown above rather than repeated per row.
| Figure | How it is obtained | Result |
|---|---|---|
| Radial section height | (D − d) / 2 | 17.5 mm |
| Mean diameter dm | (D + d) / 2 | 82.5 mm |
