Product Description
The Timken 493-D is a double tapered roller bearing cup belonging to the 495 series, designed to pair with two separate single cone assemblies to form a complete TDO (Tapered Double Outer) bearing configuration. With an outside diameter of 5.3750 inches and a double cup width of 2.125 inches, this component is built for high-load applications where overturning moments are a significant load factor. The housing backing shoulder diameter measures 5.16 inches, and the maximum housing fillet radius is 0.030 inches.
Manufactured in the United States from Timken high-alloy steel, the 493-D features an open design that permits lubrication access and precise axial adjustment. The TDO configuration allows the bearing to be used in fixed positions or permitted to float within the housing bore, offering flexibility in installation. Rated for operating temperatures from negative 65 to 250 degrees F, this cup is suited for heavy-duty industrial environments including mining, construction, agriculture, and conveyor systems.
The part number 493-D designates a double cup with a tapered outer diameter profile. It is sold as the cup (outer ring) component only; cone assemblies are not included. Weighing approximately 7.23 pounds, the 493-D ships in the original Timken VCI-treated paper wrap visible in the photos.
