Four Point Angular Contact Ball Bearings (Model: QJ1068X3 / 340) are designed to handle combined radial and axial loads in both directions, providing high rigidity and precision. The bearing has a bore diameter of 500mm, outer diameter of 80mm, and a width of 5mm. The minimum fillet radius is 404mm. It offers a dynamic load capacity of 705kN and a static load capacity of 600kN. With a limiting speed of 800 r/min for grease lubrication and 380 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 460mm, maximum outer ring diameter of 4mm, and maximum fillet radius of 53.6mm. 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.
