UCF Tapered Roller Bearing Cup OD

UCF tapered roller bearing cups are the outer rings (outer races) of a tapered roller bearing assembly. They are sold as a cup only, without the matching cone. Each cup is built to pair with a compatible cone, also called the inner race and roller assembly. Together they form a complete wheel bearing or drivetrain bearing set. Use them to replace a worn, pitted or damaged cup, or to refresh a bearing set during a rebuild.

Key Features:

• Cup-only design: The cup is the outer ring of the tapered roller bearing. The cone and rollers are separate.
• Tapered raceway: The conical raceway guides the rollers. This lets the bearing carry combined radial and axial (thrust) loads.
• Press-fit installation: The cup seats in the hub or housing bore and acts as the race the rollers ride on.
• Wide range of sizes: The UCF line covers many outside diameters and cup numbers. Match the cup number to the cone you are using.
• Common uses: Powersports, motorcycle, trailer, automotive and general machinery applications.

Replace the cup and cone together as a matched set for the longest bearing life. Clean the housing bore, press the cup in evenly and pack the bearing with grease. Choose the cup that matches your cone's part number to get proper fit and bearing performance.
