Product Description
Four Point Angular Contact Ball Bearings (Model: QJF230 / 116230) are designed to handle combined radial and axial loads in both directions, providing high rigidity and precision. The bearing has a bore diameter of 150mm, outer diameter of 270mm, and a width of 45mm. The minimum fillet radius is 3mm. It offers a dynamic load capacity of 258kN and a static load capacity of 369kN. With a limiting speed of 1350 r/min for grease lubrication and 1750 r/min for oil lubrication, and a weight of 11.8 kg, it suits various industrial setups. The mounting dimensions include a minimum inner ring diameter of 180mm, maximum outer ring diameter of 240mm, and maximum fillet radius of 2.5mm. 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.
