C.E. Smith Roller Shafts, Pal Nuts & Mounting Brackets
A replacement roller is only part of a boat-trailer support assembly. The shaft must fit through the roller and brackets, pal nuts retain it, and the mounting bracket must suit the trailer's attachment point. Compare the precise C.E. Smith sizes and included components below.
Shaft lengths and pal nuts
All dimensions below are in inches. The five shaft models are supplied with pal nuts; 10801A is a separate set of eight pal nuts for 5/8-inch shafts.
| MPN | Part type | Diameter and length |
|---|---|---|
| 10700A | Steel roller shaft | 1/2-in diameter × 5-1/4-in length |
| 10701A | Steel roller shaft | 1/2-in diameter × 6-1/4-in length |
| 10705A | Steel roller shaft | 1/2-in diameter × 12-3/4-in length |
| 10725A | Steel roller shaft | 5/8-in diameter × 8-7/8-in length |
| 10727A | Steel roller shaft | 5/8-in diameter × 13-in length |
| 10801A | Shaft-retaining pal nuts | 5/8-in shaft diameter; set of eight |
Measure before purchasing: matching shaft diameter is essential, but the bracket width, shaft length and retaining end clearance must also suit the installed assembly. The 10801A pal-nut set is not a universal fit for 1/2-inch shafts.
Complete bracket and roller supports
Unlike individual shafts, these assemblies combine a steel support bracket and roller. Compare bracket geometry and what hardware comes in the package.
| MPN | Design | Dimensions and roller | Mounting hardware |
|---|---|---|---|
| 10401G | One-piece bracket and roller | 5-in bracket width; 3-in slot; 5-in roller | Not included |
| 10403G | One-piece bracket and roller | 8-in bracket width; 6-in slot; 8-in roller | Included |
| 32003G | Two-piece adjustable roller support | 5-in width; 5-in keel roller | Included |
Before installing a replacement
- Shaft: measure its outside diameter with calipers and check length between the retaining ends.
- Roller bore: confirm that the intended roller accepts the shaft diameter; a shaft length alone does not establish compatibility.
- Bracket: note one-piece versus two-piece construction, clear opening and available adjustment.
- Mounting hardware: 10401G does not include the bracket mounting hardware; 10403G and 32003G do.
