How to read dimensions d, D, B, C, T and H
Measure the bore inside the bearing.
Front viewMeasure across the outer edges of the bearing.
Front viewMeasure the distance between the side faces.
Side viewd is the bore diameter and D the outer diameter. For standard radial bearings, B denotes the width. For tapered roller bearings, distinguish the inner ring width B, the outer ring width C and the overall assembly width T.
H may denote the overall height of a thrust bearing in the source catalogue. Always distinguish the dimensional symbol shown in the result.
The catalogue dimension in the last column may refer to width, axial height or another part dimension, depending on the design. If no symbol is given, the numerical value alone does not identify it. Check the exact symbol and meaning in the details and technical data sheet. For housings and units, d may not denote the shaft diameter.
For bearing units and accessories, other dimensional symbols have meanings specific to the design. Matching dimensions alone do not confirm interchangeability; also compare the full designation, design, clearance, seals and application requirements.

How reliable is the technical data?
Load ratings and speeds refer to the design in the source catalogue. Check them for the specific manufacturer, design and application. Matching dimensions alone do not confirm interchangeability.
“To be verified” flags conflicting or unclear values. These values are excluded from dimensional matching. We do not estimate technical parameters for designations without supporting documentation.
