Thrust Ball Bearings · 51100 reference
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.
d 17 mm · D 30 mm · T 9 mm
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 |
|---|---|---|---|
| 51103 | 17 mm | 30 mm | 9 mm |
Model-specific review
This is the largest washer-bore and outside-diameter combination in the listed thrust-ball subset. Total height remains unchanged across the subset; no load or speed ranking is inferred from the size order.
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.
