Dexter Bearing Kit K71-G02-52, 1-1/4 Inch x 3/4 Inch Spindle with Dust Cap

The Dexter K71-G02-52 bearing kit is a complete tapered roller bearing set sized for a 1-1/4 inch by 3/4 inch trailer spindle. It is built to support the hub assembly on a boat trailer or utility trailer axle, carrying the radial and thrust loads created as the wheel rotates and as the trailer turns, brakes, and travels over uneven road surfaces. The kit uses precision-tapered roller bearings, which distribute load across the full length of the roller rather than a single point, giving longer service life and more consistent rolling resistance than a straight ball bearing under the combined side and vertical loads a trailer axle sees.

Each kit includes both halves of the bearing assembly (two cones and two cups), so the inner and outer bearing races are matched and ready to press into the hub without needing to source components separately. A grease seal and cotter pin are included to retain lubricant and secure the spindle nut, and a dust cap is included to keep water, grit, and road debris out of the hub cavity. The bearings are compatible with standard grease-based lubrication used in trailer hub service.
