SKF Bearing QJ 216 MA Four Point Contact Ball Bearing 80 Mm Bore CN Axial Clearance Machined Metal Cage Bearing Steel Heavy Duty Built To Last With Dynamic Load 146 kN And Static Load 156 kN For Precision Machinery And Industrial Applications

Single 80 mm bore SKF QJ216 MA four-point contact bearing
✔️ 80 mm bore, CN axial clearance, 146 kN dynamic load, 156 kN static

The SKF QJ216 MA is a heavy-duty four-point contact ball bearing with an 80 mm bore, designed for precision machinery and industrial equipment. Its machined metal cage keeps the rolling elements evenly spaced for high rigidity and long life in presses, conveyors, and machine tools. For applications requiring sealing, sealed ball bearing variants exist, but this model is open (no sealing) to allow relubrication and easy inspection.
