Drawn cup needle roller bearing HK

single-rowplasticsteel

Open-ended drawn cup needle roller bearings consist of a needle roller and cage assembly that is held in a sleeve made of steel sheet. The sleeve serves as a parallel partner in the housing. These compact roller bearings offer the very highest load ratings in a very small space. Thanks to the sleeve, the housings can be manufactured from materials other than roller bearing steel, such as aluminum, cast iron or high-strength plastics. Because of the thin-walled design of the sleeve, it must be ensured that the housing is sufficiently solid. It is particularly important to note that the number of needles may vary while the dimension stays the same, which allows different load ratings to be achieved. The needle sorting used plays a particularly important role when it comes to precision. Closed-ended drawn cup needle roller bearings Closed-ended drawn cup needle roller bearings are closed on one side and serve as a closure for shaft ends. The rotating shaft is protected and sealed against interference. Cage types may vary depending on the size and application type. We carry various cage designs made of steel sheet and plastic. An essential property of greases and oils is the reliable mechanical separation of the rolling element from the raceway. Depending on the application, you need special types of grease to achieve this function. The following properties in particular affect the function: -the starting and operating temperature -the speed of the bearing -the external ambient conditions (moisture, contamination, vapors/gases...) We recommend a lithium complex soap grease for needle-roller bearings under normal operating conditions.
