C.E. Smith Package Roller Shaft 1/2" x 5-1/4" w/Cap Nuts - Zinc

The C.E. Smith Package Roller Shaft 1/2" x 5-1/4" with Cap Nuts in Zinc is a precision replacement component designed for trailer roller assemblies and marine equipment. This shaft serves as the core axle support for roller systems used in boat trailers, utility applications, and vehicle recovery setups. The zinc finish provides corrosion resistance in both freshwater and saltwater environments, making it suitable for coastal and high-moisture deployments where standard steel would degrade rapidly.

The shaft measures 1/2 inch in diameter with a total length of 5-1/4 inches and a maximum grip length of 4.690 inches—specifications that determine the load-bearing capacity and alignment in the roller assembly. The package includes two cap nuts, eliminating the need for separate fastener sourcing. C.E. Smith's engineering tolerances ensure smooth rotation and minimal lateral play when properly installed, critical for preventing uneven wear on wheels and reducing drag during towing or stationary storage scenarios.

This replacement shaft is essential for maintaining trailer roller systems that have experienced wear, bent axles, or corrosion-related failure. Whether you're servicing a boat trailer after extended water exposure, replacing a worn roller assembly on utility equipment, or performing preventive maintenance on fleet trailers, this C.E. Smith component restores proper wheel alignment and rotation. The zinc coating extends service life in harsh outdoor and marine conditions where unprotected steel fails within months.

Sourced directly from C.E. Smith (MPN 10700A), this is OEM-specification hardware, ensuring compatibility with existing roller frame assemblies and cap nut configurations. Proper installation requires alignment of the shaft with roller wheel hubs and secure fastening of the included cap nuts to prevent rotation and lateral movement during operation.
