Bearing weight & mass lookup
Bearing mass is a catalogue attribute. A solid-ring estimate cannot reproduce the mass of rings, rolling elements, cage and seals.

What to check
Look up the full model
Open the product record and its mass field. Similar boundary dimensions can contain different ball counts, cages and internal geometry.
Missing is not zero
A dash means the source has not supplied a normalized mass. Do not interpret it as a massless product or estimate freight from it.
Assemblies need a defined scope
A unit mass can include a housing and fasteners; a bearing-only mass may exclude packaging, grease or accessories. Compare like-for-like scopes.

How to measure bearing bore, outside diameter & width
Record the component marking before measuring. The size finder expects bore d, outside diameter D and width B in that order, not the order in which the numbers happen to appear on a label.

One inch is exactly 25.4 mm. Unit conversion changes the expression of a size, not its physical size or tolerance.

Manufacturer terminology is retained in the product records. Technical reference basis: JTEKT Basic Bearing Knowledge (boundary dimensions, tolerance classes and lubrication); NSK Bearing ABCs (lubrication, designations and clearance); NTN technical FAQs (closure codes and component interchange); SKF rolling-bearing selection and maintenance references.
