This professional-grade tapered roller bearing kit from AB Tools is designed for mechanics, trailer owners, and DIY enthusiasts needing a reliable replacement for unbraked hubs. Offering exceptional radial and axial load capacity and high shock resistance, it ensures smooth and secure wheel rotation for various trailer and automotive applications. While the unit provides superior durability through high-quality bearing steel, users must verify their specific hub dimensions and axle compatibility before installation to ensure a precise, non-binding fit.

This kit fits hubs requiring a 30203 bearing with dimensions 17mm ID, 40mm OD, and 13.25mm width. Please verify these measurements against your old part or manual.
This bearing is specifically listed for ALKO 369689 unbraked hubs. It is not recommended for braked systems unless specified by your trailer's technical manual.
No, the kit includes the bearing and the racer. You should source a high-quality, lithium-based wheel bearing grease separately.
Each pack contains one complete set, including one bearing cone and one matching racer.
This is a standard 30203 tapered roller bearing.
Check the castle nut tension; if properly tightened, the bearing likely needs replacement due to race wear.
Immediate inspection is required; the bearing likely lacks adequate lubrication or has suffered internal damage from contaminants.
Ensure the hub surface is free of rust or debris; use a straight-edged seating tool to prevent the race from tilting.
Before starting your installation, ensure the hub cavity is thoroughly cleaned of old, contaminated grease. When installing, use a proper bearing press or a suitable drift to seat the race; avoid striking the bearing surface directly to prevent indentations. Always apply a high-quality, water-resistant wheel bearing grease during assembly to provide a protective barrier against moisture and corrosion. Compatibility is specific to the 17mm x 40mm x 13.25mm size category (Bearing Number 30203). Regularly inspect the trailer wheel for excess play or clicking sounds, which are primary indicators that the bearing requires adjustment or replacement.
