Boundary dimensions for this record match the SKF 61809 source entry reviewed on 11 October 2026. This confirms dimensions only. Exact variant, current load and speed ratings, and cross-brand interchange still require confirmation.

SKF dimension source

Load ratings, speed limits, mass and internal geometry are withheld until the exact manufacturer variant and source are recorded. Unknown values are not zero.

No cross-brand interchange or supplier stock availability has been established for this record. Manufacturer designations can differ even when boundary dimensions match.

1. Record the full marking from the bearing or equipment parts list, preserving letters, slashes and hyphens.
2. Confirm bore, outside diameter and width against the exact manufacturer catalog entry.
3. Check closures, clearance, cage, tolerance, lubrication and any special design requirements.
4. Compare manufacturer-specific load and speed data with the equipment requirements before selecting a replacement.

A shared number or a dimension match alone does not establish replacement suitability.
