A missing or worn boat-trailer roller shaft is best matched by measured diameter, overall length and the shape of the bracket it passes through. C.E. Smith offers different shaft lengths plus complete roller supports. Use this reference to distinguish the individual hardware before ordering.

Identify a replacement roller shaft

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

How to identify the original support

  • 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.
