61902E is a deep groove ball designation documented on BearingIndex from 1 manufacturer publication. The published boundary dimensions are 15 × 28 × 7 mm. The designation ends in bore code 02, which resolves to a 15 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.
| Manufacturer | Dynamic load rating (kN) | Static load rating (kN) | Limiting speed — grease (rpm) | Limiting speed — oil (rpm) | Source recorded | |
|---|---|---|---|---|---|---|
| LYC 61902E | 4.31 | 1.94 | 24000 | 30000 | 2026-09-23 | Request |
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 | 6.5 mm |
| Mean diameter dm | (D + d) / 2 | 21.5 mm |
| Speed factor dm · n | mean diameter × highest published limiting speed | 645,000 mm·min−1 |
| C / C₀ load ratio | dynamic ÷ static load rating | LYC 2.22 |
