Four Point Angular Contact Ball Bearings (Model: QJF1034X3 / 170) are designed to handle combined radial and axial loads in both directions, providing high rigidity and precision. The bearing has a bore diameter of 279.5mm, outer diameter of 46mm, and a width of 2.1mm. The minimum fillet radius is 255mm. It offers a dynamic load capacity of 388kN and a static load capacity of 1200kN. With a limiting speed of 1500 r/min for grease lubrication and 198 r/min for oil lubrication, and a weight of kg, it suits various industrial setups. The mounting dimensions include a minimum inner ring diameter of 252mm, maximum outer ring diameter of 2mm, and maximum fillet radius of 12.7mm. 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.
