FAQ What is the matching cone for this Timken 742 cup?The Timken 742 cup is most commonly matched with cone assemblies from the 749 series, such as the Timken 749, 749A, or 749S, to form a complete single-row tapered roller bearing. Is this cup made of standard bearing steel?Yes, Timken uses high-quality, case-carburized bearing steel which provides a hard, wear-resistant surface and a tough, ductile core to handle shock loads. Can this bearing cup be used in high-temperature applications?Standard Timken bearings are typically rated for continuous operation up to 120 deg C (250 deg F). For temperatures exceeding this, special materials, heat treatments, and lubricants may be required. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
