Product Introduction
The LM48548/LM48510 (widely known in the aftermarket as Set 5) is one of the most universally adopted inch-size tapered roller bearings in the world. Comprising the LM48548 inner cone assembly and the LM48510 outer cup, this bearing is the foundational rotational component for millions of light vehicle rotors, utility trailers, and industrial spindles. Because it manages the direct weight of the vehicle and the lateral stress of turning, perfection in the roller-to-raceway contact angle is vital. Bypassing large-scale automated bulk testing, our specialized team at Linqing Xinshengdi Bearing Co., Ltd. manually pairs and inspects the seating of every cone and cup set within our dedicated assembly workshop. This boutique, hands-on validation ensures your wholesale buyers receive a product that completely eliminates wheel wobble and ensures precise, low-friction rolling.
Applications
Front wheel hubs of light passenger cars and pickup trucks.
Axles for utility, boat, and heavy-duty cargo trailers.
Industrial conveyor rollers and low-speed gearboxes.

FAQ
Q: Must I replace both the cone and the cup at the same time?
A: Yes, absolutely. Bearings wear into each other creating a matched pattern. Placing a new cone into an old, worn cup will destroy the new bearing within miles. Always replace them as a complete set.
Q: How tight should I torque the axle nut when installing this bearing?
A: Tapered wheel bearings require a specific "preload" procedure (usually tightening to a specific torque while spinning, then backing off a fraction of a turn). You must follow the exact OEM service manual for the vehicle to prevent burning up the bearing.
