Product Description
Four Point Angular Contact Ball Bearings (Model: QJF2956X3-1 / 116756YS) are designed to handle combined radial and axial loads in both directions, providing high rigidity and precision. The bearing has a bore diameter of 280mm, outer diameter of 389.5mm, and a width of 65mm. The minimum fillet radius is 4mm. It offers a dynamic load capacity of 325kN and a static load capacity of 628kN. With a limiting speed of 800 r/min for grease lubrication and 1100 r/min for oil lubrication, and a weight of 25 kg, it suits various industrial setups. The mounting dimensions include a minimum inner ring diameter of 252mm, maximum outer ring diameter of 362mm, and maximum fillet radius of 3mm. Ideal for precision machine tools, small to medium-sized industrial gearboxes, this bearing ensures reliable operation in different machinery. Manufactured to high-quality standards, it delivers exceptional precision and durability under varying loads, supporting both radial and bidirectional axial load requirements. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
