Product Description
Four Point Angular Contact Ball Bearings (Model: QJ1040 / 176140) 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 310mm, and a width of 51mm. The minimum fillet radius is 2.1mm. It offers a dynamic load capacity of 294kN and a static load capacity of 473kN. With a limiting speed of 1100 r/min for grease lubrication and 1400 r/min for oil lubrication, and a weight of 15 kg, it suits various industrial setups. The mounting dimensions include a minimum inner ring diameter of 228mm, maximum outer ring diameter of 282mm, 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.
