Product Overview
Tapered roller bearing hubs were used on the V1 hub; this type of bearing provides more contact surface than the ball bearings used on the OEM hub, thereby increasing its load capability and durability. To improve the hub, an upgrade kit was created.
Upgrade Kit (V1): While V1 made significant strides in offering more durable hub, Mazda Motorsports created an upgrade kit (two per car needed) that results in the V2 hub package.
The new V2 hub has key updates that are improved over the original design. As seen on the cross-sectional drawing below, the colored sections indicate the updates to the V2 hub design.
- Starting at the top with the spindle backing plate, we have integrated an O-ring groove into the plate to prevent water and dirt intrusion from the back side of the hub.
- The rear seal has been updated to further prevent contaminates from entering the hub to prolong the service interval duration/life of the hub.
- To ease installation and setup for racers and teams, two spacers have been added to the design: 1) the middle bearing spacer controls the bearing preload clearance and ensures the correct tension for heat expansion; and 2), the snout spacer provides the additional footprint for the outer bearing to rest on for the proper support under load.
- The OEM lock nut (torqued to OEM spec and properly staked) holds everything in place for optimal performance.
