Imperium OneSet Hub Assembly (TN Trailer Axle)

Imperium™ OneSet is a complete trailer wheel-end assembly engineered to establish and preserve the conditions bearings, seals, and lubrication need to reach their intended service life.

Controlled-tolerance bearings and a precision-ground spacer establish the correct bearing setting at the factory, eliminating manual bearing adjustment during installation. The assembly mounts directly onto the spindle, reducing technician variability, simplifying installation, and getting equipment back into service faster.

Every assembly includes the Vytor™ Xtreme-Duty Wheel Seal and an application-matched torque nut. Together, these components form the foundation of The Controlled Operating Environment™: our system-level approach to maintaining stable, contaminant-reduced conditions inside the wheel-end. By controlling bearing setting, lubricant retention, contaminant intrusion, and spindle retention as one connected system, Imperium OneSet is backed by an industry-leading 750,000-mile limited warranty.

Key Features:

• Factory pre-adjusted bearing system: Eliminates manual bearing adjustment, reduces installation variability, and lowers the risk of excessive preload or end play.
• Vytor Xtreme-Duty Wheel Seal included: With integrated VXR™ Filter, the seal provides a stronger barrier against contaminant intrusion while helping retain lubricant and protect the bearing environment.
• Application-matched torque nut included: The proper torque nut is supplied with the assembly instead of being treated as a separate sourcing decision.
• ABS-ready design: A durable, corrosion-resistant ABS tone ring is integrated into the hub configuration. Supports dependable wheel-speed sensing and proper trailer ABS operation.
• 750,000-mile limited warranty: Backed by an industry-leading 750,000-mile warranty. Delivers long-term protection for the fleet’s investment.
