CE Smith Boat Trailer Bearing Kit for 1-1/16”–1-3/8” Tapered Spindle — Complete Hub Rebuild with Bearings, Races & Seal

The CE Smith Bearing Kit is a complete, marine-grade replacement set designed to service one trailer wheel on 1-1/16” to 1-3/8” tapered spindles for reliable, smoother towing.

Whether you trailer a small fishing boat or a recreational runabout, wheel bearings are a wear item that directly affect safety and performance. This all-in-one CE Smith kit collects the frequently replaced components—inner and outer bearings, two races, a grease seal and a cotter pin—plus the basic tools needed to remove and install them. With parts sized for common tapered spindles, the set lets you return a noisy or rough hub to quiet, free-rolling service without sourcing individual components from multiple suppliers.

How do I know this kit fits my trailer spindle?

Fit is determined by the tapered spindle dimension: this kit is built for spindles that measure between 1-1/16” and 1-3/8”. Inspect your trailer hub or spindle stamping, or measure the spindle diameter where the bearing seats to confirm compatibility. If in doubt, compare part numbers from your existing bearings or consult the trailer manufacturer for the spindle spec.

• Designed for 1-1/16” to 1-3/8” tapered spindles
• Includes inner and outer bearings and two races for a complete hub rebuild
• Fits most small to mid-size boat trailers commonly used for fishing and recreational boats

What’s included and why each piece matters?

The kit groups the essential replacement parts you need to repair one wheel hub. Bearings carry the load and allow rotation; races provide the hardened track for the bearings; the grease seal keeps lubricant in and contaminants out; and the cotter pin secures the spindle nut. The included basic tools speed installation and help ensure a correct, safe reassembly.

• Outer and inner bearings — restore smooth rotation and reduce heat from friction
• Two races — replace worn bearing tracks to prevent premature failure
• Grease seal — maintains lubrication and protects against water intrusion
• Cotter pin and tools — secure the spindle nut and simplify installation

How will installing this kit affect trailer performance?

Replacing damaged or worn bearings and seals returns the wheel to proper alignment and friction levels, which reduces noise, heat, and uneven tire wear. A correctly serviced hub rolls more easily, improves towing stability, and lowers the chance of hub failure while launching or trailering. Regular replacement as part of preventative maintenance extends the service life of the trailer axle and wheels.

• Reduces bearing noise and vibration for quieter towing
• Prevents water intrusion that causes rust and bearing degradation
• Helps maintain correct wheel alignment and tire wear

What tools or skills are required to install the kit?

Basic mechanical ability and common hand tools are sufficient for most hobbyists to replace a single wheel hub on a trailer. Typical steps include removing the wheel, backing off the spindle nut, removing the old bearings and races, pressing or seating the new races, greasing the bearings, installing the seal, and torquing the nut to specification. If you’re unfamiliar with bearing preload and torque settings, consult a service manual or a professional mechanic to avoid over- or under-tightening.

• Basic wrench set and a breaker bar for spindle nut removal
• Bearing grease and a seal driver or suitable arbor for seating seals and races
• Torque wrench and knowledge of your trailer’s torque/preload specs

Who this is for: boat owners, trailer hobbyists and marine technicians who need a reliable, single-wheel repair solution for small to mid-size trailers. The CE Smith Bearing Kit suits anyone wanting to replace worn bearing components quickly with marine-ready parts from a recognized trailer-parts manufacturer. It’s a practical choice for preventative maintenance, seasonal checkups, or on-the-water repairs where restoring safe, smooth wheel operation is the priority.
