Product Description
Four Point Angular Contact Ball Bearings (Model: QJF3940X3 / 116740) are designed to handle combined radial and axial loads in both directions, providing high rigidity and precision. The bearing has a bore diameter of 200mm, outer diameter of 289.5mm, and a width of 58mm. The minimum fillet radius is 2.1mm. It offers a dynamic load capacity of 235kN and a static load capacity of 384kN. With a limiting speed of 1100 r/min for grease lubrication and 1400 r/min for oil lubrication, and a weight of 13.2 kg, it suits various industrial setups. The mounting dimensions include a minimum inner ring diameter of 223mm, maximum outer ring diameter of 267mm, and maximum fillet radius of 2mm. 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.
