3720
A tapered roller bearing outer race (cup) for heavy-duty truck wheel ends. It works with a matching cone and roller assembly to support axle loads and enable smooth wheel rotation. Commonly used in the outer position of steer axle wheel bearings on many medium- and heavy-duty trucks. Replacement is required when bearing surfaces show pitting, spalling, or excessive wear, typically done as a set with the cone (e.g., Timken 3782) during brake or wheel seal service.
Primarily used as the outer wheel bearing race on front steer axles. Always verify exact year, make, and axle model compatibility with the vehicle manufacturer. Replace together with the matching cone (e.g., Timken 3782).
