Double Rows Angular Contact Ball Bearings 4052D

Double Row Angular Contact Ball Bearings (Model: 4052D) 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 260mm, outer diameter of 400mm, and width of 140mm. With fillet radii of 4mm (r12) and 2mm (r34), it ensures smooth operation and structural integrity. It offers a dynamic load capacity of 436kN and static load capacity of 735kN. Suitable for high-speed applications, it has a limiting speed of 800 r/min (grease lubrication) and 1050 r/min (oil lubrication), with a weight of 58 kg. Ideal for heavy industrial machinery, rolling mills, 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.
