Double Row Angular Contact Ball Bearings (Model: 4034D) with a standard contact angle of 15° are engineered for applications requiring high radial and axial load capacity in both directions. optimized for high-speed applications with moderate axial loads. This double-row configuration provides exceptional radial and axial load capacity in both directions, with enhanced stiffness and precision compared to single-row designs. The symmetrical arrangement ensures uniform load distribution across both rows of balls, minimizing wear and extending service life under heavy or fluctuating loads. The bearing has a bore diameter of 170mm, outer diameter of 260mm, and width of 90mm. With fillet radii of 2.1mm (r12) and 1.1mm (r34), it ensures smooth operation and structural integrity. It offers a dynamic load capacity of 208kN and static load capacity of 385kN. Suitable for high-speed applications, it has a limiting speed of 1300 r/min (grease lubrication) and 1700 r/min (oil lubrication), with a weight of 15.5 kg. Ideal for precision machine tools, high-speed gearboxes, this bearing provides reliable performance in demanding industrial environments. Manufactured to strict quality standards, it delivers exceptional precision and durability under varying loads. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
