Practical for unforgiving terrain and extreme applications such as mining, where the extremely short service life of wheel bearings means costly downtime, the kits consist of two major innovations created with Terrain Tamer tooling.

The first is a heavy-duty bearing that has been made in Japan, with a Rockwell hardness rating 2.5 points higher than the OE equivalent. Combining a new forging technique with an upgraded heat treatment procedure to enable a longer service life, the new technologies used to create the bearing means that they hold up to contaminants better, for longer, doubling the service life in clean grease, and working up to 10 times longer in contaminated lubricant.

The second element is a range of Heavy-Duty hub seals which rotate on their own internal surface, without relying on the condition of the shaft and eliminating wear on other components.

These seals utilise a labyrinth construction with four sealing surfaces, to better prevent the loss of oil and lubricating fluids and better protect against the ingress of dirt and other contaminants, making them perfectly suited to harsh, muddy and dusty conditions and ensuring both extended seal and bearing life.

Heavy duty wheel bearing kits & and products like our gearbox bearing kits include all required components such as gaskets, nuts, gear lever seats and bushes, boots, washers etc and are are covered by 12-month warranty.
