Entity bushed needle roller bearing(NK Series) is a kind of high capacity bearing with small sectional height. It can operate very flexibly even with the light alloy bearing seat due to its high hard outer ring. There are two series: metric and inch series. Both of which are structured with retainer, full needle and sealing types. Besides, the entity bushed needle roller bearings are divided into two kinds: that with inner ring and without ring. The center shaft is used as rolling body tray for those without inner ring so that its size is even smaller.
The solid ferrule needle roller bearing is compact in structure and small in radial size, and can withstand larger radial loads. In addition to the full complement of needle roller bearings, the other uses of a high-rigidity needle retainer is correctly guides the needle roller parallel to the axis. Accurate machining of the shaft will improve the accuracy of the entire bearing.In general case, the mounting of the needle roller bearings needs compact combination so that the thin wall bush can be well supported. The heavier the load is, the selection combination is bigger, especially when impact load should be considered. Further more, it is necessary to consider the combination of materials and temperature differences.
Entity bushed needle roller bearing and others needle bearings, such as drawn cup needle roller bearings, thrust needle bearings and retainer assembly bearings are suitable for the applications of smaller space and high capacity, widely use in the automotive parts, the drivetrain system of mechanical engineering, the steering system and the connecting rod.
