Key Features
- OEM-Spec Cup Surface Hardness — Manufactured to the same case-hardened steel specification as the original, ensuring the tapered roller bearing seats and tracks correctly under load.
- Drop-In Hub Compatibility — Machined to the same outer diameter and taper angle as the factory cup, so it presses into the hub bore without any modification to the housing.
- Broad Trailer Fitment — Confirmed fit for Multiquip trailer models TRLR45H, TRLR45E, TRLR502XFH, TRLR502XFE, TRLRSG1600XFH, and TRLRSG1600XFE.
- Smooth Load Transfer — A correctly seated bearing cup distributes axle load evenly across the roller contact surface, preventing premature bearing wear and uneven tire loading.
- Tow-Safe Integrity — Bearing cup failure on a towed trailer can lead to wheel separation; using the correct OEM cup maintains the structural integrity of the wheel hub assembly during transport.
The inner bearing cup — also known as a bearing race — is the hardened outer ring that the tapered roller bearing sits against inside the wheel hub. It works in tandem with the bearing cone to transfer the weight and lateral forces of the trailer axle smoothly to the wheel, allowing the hub to rotate freely with minimal friction. When the cup becomes worn, pitted, or scored, the bearing rollers lose consistent contact with the race surface, which causes rough rotation, excess heat, accelerated bearing failure, and in severe cases, unsafe wheel movement during towing.
