Deep Groove Ball Bearings (Model: 618/1240X1) are the most widely used type of rolling bearings, capable of carrying both radial and axial loads simultaneously. Manufactured from ISO 9001-certified high-carbon chromium bearing steel (GCr15), they undergo quenching and tempering treatments to ensure high hardness, good wear resistance, and fatigue resistance. With a bore diameter of 1240mm, outer diameter of 1480mm, and width of 112mm, these bearings offer a dynamic load capacity of 930kN and static load capacity of 2660kN. Making them suitable for extra-large industrial equipment (e.g., mining machinery, large motors). The bearing uses a Standard steel cage to ensure stable guidance of rolling elements and uniform load distribution during operation. All products comply with ISO standards and are suitable for global industrial and mechanical engineering applications. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
