Meritor’s wheel-end solutions – including hubs, brake drums and hub assemblies – meet or exceed OEM specifications for heavy-duty commercial and industrial vehicles. Our products are engineered with materials that reduce weight without ever sacrificing strength and durability.

A low-maintenance hub system is key for improved overall vehicle performance and lower lifecycle cost. Meritor offers a reliable wheel-end design that helps keep vehicles on the road with lower operating costs: the PreSet® hub assembly.  

PreSet uses the strength and durability of the Meritor precision-manufactured ductile iron hub in combination with ConMet’s PreSet bearing concept. With periodic inspections, actual service intervals can extend up to 500,000 miles. PreSet is fully field serviceable with conventional, readily available parts (no special tools, equipment or procedures are required).

PreSet is pre-assembled to arrive ready for installation, reducing the risk of misalignment or damaged components during installation and the pre-adjusted bearings ensure consistency and maximum life.

Precision-ground spacer secures proper bearing adjustment whilst special-tolerance inner and outer tapered roller bearings are designed and selected for extended life. The robust gasket and proven venting technology protect against moisture and other contamination that can reduce bearing and seal life.  

Finally the precision-machined ductile iron hub for high tensile strength ensures maximum strength.
