Structure and designation
Review the shaft washer, housing washer and complete axial stack. The recorded T is complete bearing height, not the thickness of one washer or a radial bearing width. Confirm the axial load arrangement before selection.
The d and D values belong to different washers. T is the complete single-direction bearing axial height, not radial width B.
Family-specific dimensions
The d and D values belong to different washers. T is the complete single-direction bearing axial height, not radial width B. Values are source-published millimetre references unless identified as a structural field.
| Model | d — Shaft washer bore | D — Housing washer outside diameter | T — Complete bearing axial height |
|---|---|---|---|

Model-specific review
The listed 51103 has a larger shaft-washer opening and housing-washer outside diameter but the same total height. An axial space check alone would not distinguish these two reference assemblies.
Specification boundary
These values describe the cited engineering reference. They do not verify LTO-specific load ratings, speed limits, material, precision, clearance, seals, application suitability or interchangeability. Provide the complete designation, quantity, drawing and operating conditions for quotation review.
