Fleet managers know that once a hub begins leaking, it’s usually too late. But what leads to those failures in the first place?

A recent study by an independent, third-party laboratory highlights just how far reality can diverge from accepted cl...

The Hub Corp’s new approach to hubcap architecture enables capabilities that simply were not available within oil bath wheel-end systems before. This evolution requires revisiting, and evolving, the existing Recommended Practices.

The Xtractor hubcap asks the industry to look at what is working in the field and decide whether current standards reflect the best available practice, or simply the most recent one. As data matures, we will share it openly and participate in any technical review TMC chooses to conduct.

Wheel seals will always be a wear item, but the damage they allow doesn’t have to be inevitable.
