The Timken 3726 is a single-cup tapered roller bearing outer ring from Timken's 375 Series, designed to pair with a matching cone assembly to form a complete single-row tapered roller bearing unit. Cup part number 3726 carries an outer diameter of 3-3/4 inches and a cup width of 15/16 inches, with standard tolerance and a maximum housing fillet radius of 0.130 inches. The cup is manufactured from Timken high-alloy steel and conforms to ABEC 1 (Tolerance Class P0) standards. As a separable component, it allows for independent installation and adjustment of the cone assembly during equipment setup. Single-row tapered roller bearings of this type are commonly used in gearboxes, conveyor systems, wheel hubs, agricultural machinery, and construction equipment where combined radial and single-direction axial loads must be managed. The 3726 cup is compatible with multiple Timken cone part numbers including the 3780 and 3782, making it a widely cross-referenced component across heavy-duty industrial and automotive drivetrain applications. The item is in original Timken packaging. MPN 3726. Manufacturer is The Timken Company, Canton, Ohio.
