6420 Bearing Identification and Dimensions

The 6420 boundary dimensions match LNB's own deep groove ball bearing listing, reviewed on 11 October 2026. The source identifies the manufacturer as LNB. These dimensions do not verify an SKF product or a replacement across brands.

LNB 6420 manufacturer source

Exact SKF designation and cross-brand interchange remain unverified. Load ratings, speeds, mass and internal geometry remain withheld for this generic record because they depend on the manufacturer and variant.

LNB provides a matching dimension listing for this designation. 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.
