Buying Guide: Key Considerations For Trailer Bearing Seals
- Seal size compatibility: Confirm inner diameter (ID) and outer diameter (OD) as well as the width to match your hub. Mismatched seals can leak or fail early.
- Spindle and axle compatibility: Check whether your trailer uses Dexter, Texcom, or standard EZ-Lube spindles and the axle rating (2,000–7,000 lbs) to pick the right kit.
- Seal type and lubrication: Double-lip seals provide better protection against contaminants. EZ-Lube compatible seals are designed for easy maintenance.
- Material durability: Chrome steel bearings resist wear; sealed components and dust covers help extend life in exposed environments.
- Installation considerations: Ensure cotter pins and dust covers are included; inspect inner rings and cages for smooth rotation before install.
- Maintenance frequency: Regularly inspect seals for cracks, tears, or oil leaks, especially after long hauls or rough terrain.
