Bendix UniSync Trailer Hub and Rotor System

Help maintain ABS performance

The tone ring is press-fit mounted on the hub and protected within the rotor barrel. This design shields the tone ring from heat, corrosion, and damage that can lead to signal loss and anti-lock braking system (ABS) faults, helping maintain ABS performance.

Longer pad and rotor life

The Bendix friction couple is designed to work together for consistent braking and reduced wear over time.

Longer service intervals
More predictable maintenance planning
Lower cost per mile
Reduced CSA risk for rotor cracks

Brake pads and rotor on a trailer wheel-end

15 lb. less per wheel-end

The austempered ductile iron (ADI) hub delivers aluminum-like weight with the strength and durability of iron. At 120 lb. per wheel-end, the UniSync ADI hub/iron rotor saves 15 lb. versus a typical 135 lb. iron hub/iron rotor, or 60 lb. per tandem axle trailer.

For optimized performance, improved uptime, and single-source support, combine the UniSync Hub and Rotor with Bendix^® ADB22X^®-LT air disc brakes, EnduraSure^®-Pro spring brakes, and iSense^™ Pro wear sensing.

Your UniSync questions, answered

How does UniSync help protect the tone ring and ABS function?

The tone ring is press-fit mounted on the hub and protected inside the rotor barrel. This position shields the tone ring from heat, corrosive road exposure, and damage that can affect the wheel-speed sensor signal, helping maintain ABS performance and reduce trailer braking stability issues.

How much weight can my trailer save?

The UniSync ADI hub and iron rotor weigh 120 lb. per wheel-end, compared with 135 lb. for a typical iron hub and iron rotor. That difference saves 15 lb. per wheel-end, or 60 lb. per tandem axle trailer, supporting productivity in payload-sensitive operations.

Can I select individual wheel-end components?

Yes. You can select individual components from the Bendix wheel-end lineup or specify the complete system. The complete trailer wheel-end combines UniSync with ADB22X^®-LT air disc brakes, EnduraSure^®-Pro spring brakes, and iSense^™ Pro wear sensing, with single-source support from Bendix.

How does the Bendix friction couple help lower total cost of ownership?

The UniSync™ hub and rotor helps lower total cost of ownership through a matched Bendix friction couple. Rotor metallurgy and pad formulation are designed to work together, delivering consistent braking while reducing wear over time.
