Product Description

The 4T-LM12710 NTN is designed as a cup for single-row tapered roller bearings. This component serves as the outer ring that pairs with a separately available cone — which houses the rolling elements — forming a complete tapered roller bearing. Both rings feature conical raceways, complemented by conical rollers, allowing the bearing to support both radial and axial loads in one direction. The capacity for axial load increases with the angle between the outer ring and the bearing's centre line.

The tapered geometry effectively minimizes sliding movements between the raceways and rollers, thus reducing wear on components. It is crucial to apply a minimum load for optimal bearing function. Since the cone and cup are separable, they facilitate easy mounting, and adjustments of end play (axial clearance) or preload can be made by axial movement during assembly.

For dependable bearing performance, it is advisable to replace the cone and cup simultaneously, ensuring both parts are from the same manufacturer. This recommendation helps avoid issues due to differing internal profiles, material variations, and tolerance discrepancies. Always pair the 4T-LM12710 NTN with a compatible cone from the same manufacturer.
