Four Point Angular Contact Ball Bearings (Model: QJF1072 / 116172) are designed to handle combined radial and axial loads in both directions, providing high rigidity and precision. The bearing has a bore diameter of 360mm, outer diameter of 540mm, and a width of 82mm. The minimum fillet radius is 5mm. It offers a dynamic load capacity of 577kN and a static load capacity of 1330kN. With a limiting speed of 600 r/min for grease lubrication and 800 r/min for oil lubrication, and a weight of 69.2 kg, it suits various industrial setups. The mounting dimensions include a minimum inner ring diameter of 405mm, maximum outer ring diameter of 495mm, and maximum fillet radius of 4mm. Ideal for textile machinery, medium-duty industrial transmission systems, 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.
