The WINTERS 7323 Bearing Race Wide 5 Outer is the outer tapered roller bearing race for Wide 5 racing hubs, the standard wheel and hub pattern used across dirt and asphalt circle track cars. It seats inside the hub bore and provides the hardened surface the outer bearing rolls against, so it carries a share of the cornering and braking load every lap. Racers running Winters Wide 5 hubs replace this race during routine bearing service or when a spun bearing scores the hub. It pairs with the matching Wide 5 inner race and the corresponding outer bearing cone.
This is a tapered roller bearing race machined from steel for the outer position of a Winters Wide 5 hub. Per the available specifications, it measures a 2.155 in bore, a 3.35 in race diameter, and 0.608 in thickness, dimensions that match the factory Wide 5 hub bore so the race presses in square and holds the bearing cone in proper alignment. A race that is worn, pitted, or galled lets the bearing run with play, which shows up as wheel wobble, heat, and uneven brake pad contact. Because the race and bearing cone wear as a matched set, most racers install both at the same time rather than reusing an old race against a fresh cone. TSA stocks the companion bearings and the full Wide 5 bearing kit for a complete service.
Reach for the 7323 when you are rebuilding a Wide 5 hub between race weekends, chasing a wheel-bearing knock, or replacing a hub that scored its race during a bearing failure. Knock the old race out, clean the bore, and drive the new one in until it bottoms against the hub shoulder, then pack and set the bearing to spec.

It is the outer bearing race for a Winters Wide 5 racing hub. The race is the hardened steel surface that the outer tapered roller bearing rides against inside the hub bore, carrying cornering and braking loads. It is a wear item replaced during bearing service or after a bearing failure scores the hub.
Per the available specifications, the 7323 has a 2.155 in bore, a 3.35 in race diameter, and a thickness of 0.608 in. Those dimensions match the factory Wide 5 hub bore so the race presses in square and holds the bearing cone in proper alignment.
Yes. The race and its mating bearing cone wear as a matched set. Running a new cone against an old, pitted race causes premature wear and bearing play. Most racers install both pieces together, which is why they are commonly sold in a Wide 5 bearing kit.
No. The 7323 is the outer race only. The inner position of a Winters Wide 5 hub uses a different race with its own dimensions. Order the matching inner race separately when servicing both ends of the hub.
