UNIT BEARING HUBS
OEM unit bearings fail due to neglect and lack of maintenance. Generally, roller taper bearings (spindle type) take more maintenance than a unit bearings hub. By design, unit bearings are pre-set load, pre-greased, pre-sealed, to protect taper roller bearings from debris and contaminants. By eliminating the need to manually set, pack and pre-load the bearing, unit bearings simplify both installation and maintenance. A fundamental benefit of unit bearing hubs is that they maintain the original OEM design parameters of the vehicle’s safety (ABS braking), load capacity and durability.
HEAT SPACER CLAMP RINGS
The most significant cause of hub failure is heat, that if left unchecked reduces the lifespan and accelerates the failure of hubs. Excessive heat causes the breakdown of grease, the premature wear and tear of bearings, and the failure of protective seals. All of these ill effects are relieved through use of heat spacer rings.
By using the same technology used in NASCAR, heat spacers address heat related issues by creating a barrier between the brake disc and the hub assembly. Essentially, through the introduction of heat spacers, the heat transferred to the hub decreases in direct proportion to the surface area in contact with the rotor. This not only protects the hub but also increases the clamping force for a tighter connection to your wheels.
Secondly, heat spacers provide protection through use of premium grade stainless steel. The high temperature strength and corrosion resistance of stainless steel helps to preserve the structural integrity of the hub regardless of the heat created by the rotors. These natural properties improve durability while also helping to keep hubs from exceeding optimal heat thresholds.
Lastly, heat spacers allow there to be more surface area between the hub and the rotor for cooling. By increasing the available surface area for the dissipation of heat, heat is expelled through convection with the air instead of through direct contact with the hub itself.
