What is a preset bearing?
“Preset” is a method to reduce the size of upper plates of sliding bearings in order to save cost. Note: “Preset” refers to the displacement of a certain distance of sliding bearings with respect to upper bearing plates during installation of bearings.
What is a preset hub?
PreSet Plus hub assemblies include a newly designed bearing spacer that optimizes clamp load and maximizes performance and durability. Also included are ConMet bearings which are engineered to extend service life and help prevent field issues in the most demanding applications.
How much endplay should a preset bearing assembly have?
The difference between too loose or too tight, according to The Technology and Maintenance Council’s Recommended Practice RP 618 for wheel bearing adjustment, is between one and five thousandths of an inch (. 001 – . 005). To achieve the desired amount of end play, RP 618 offers a nine-step process.

What are the features of a preset hub?
For more than 20 years PreSet hubs have been the go-to wheel end for commercial vehicles in North America. We’ve built on the success of our PreSet hubs by developing PreSet Plus ® with standard features like a fully integrated spindle nut design, an optimized wheel spacer, magnetic fill plug, and ConMet seal and bearings.
What kind of bearings does Meritor preset hub have?
The hub subassembly includes an integral tooth wheel for a vehicle equipped with an anti-lock braking system (ABS). PreSethub assemblies also are equipped with pre-installed bearings, cups and cones, and oil seals and studs. A precision tubular spacer between the bearings eliminates manual bearing adjustments.
What’s the difference between wheel bearings and hub bearings?
A major difference between the two is how they are assembled. Wheel bearings can be taken apart, lubricated and reassembled to be used again. Hub bearings are pre-packed at the manufacturer’s factory and are sold and installed as a complete unit. These cannot be taken apart for re-lubrication, but must be replaced.
Why do you need a wheel hub assembly?
The wheel hub assembly is also critical to your anti-lock braking system (ABS) and the traction control system (TCS). Besides bearings, hub assemblies contain the wheel speed sensor that controls your vehicle’s ABS braking system. The sensor constantly relays to the ABS control system how fast each wheel is turning.

Can a hub nut be used for the outer wheel?
Yes. For the 1-1/8 inch stud, the same nut can be used as for the outer wheel of a drive or trailer hub dual-wheel application. A different, unique nut is used for the 3/4 inch stud.
