Product Description
Double Row Angular Contact Ball Bearings (Model: 4946X3D/W33) 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 230mm, outer diameter of 329.5mm, and width of 80mm. With fillet radii of 3mm (r12) and 1.1mm (r34), it ensures smooth operation and structural integrity. It offers a dynamic load capacity of 242kN and static load capacity of 500kN. Suitable for high-speed applications, it has a limiting speed of 850 r/min (grease lubrication) and 1100 r/min (oil lubrication), with a weight of 23.5 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.
