Needle roller thrust cylindrical roller combined bearing needle roller bearing ZARN4580/TN

Combined needle roller bearings
The combined bearing is a rolling bearing composed of the above two or more bearing structures in a set of bearings at the same time. The combined bearing is a positioning or one-way positioning bearing with the smallest radial section height.
The combined needle roller bearing is a combination of a radial needle roller bearing and a thrust bearing, so it can bear radial and axial loads. The combined needle roller bearing locates the fixed end bearing arrangement in a small radial space. ZARN and ZARF type are needle roller and bidirectional thrust cylindrical roller combined bearings, and Zarf type are needle roller and bidirectional thrust cylindrical roller combined bearings, which are suitable for screw support such as CNC machining centers.
Features of combined needle roller bearings
COMBINED NEEDLE ROLLER BEARING
Combined needle roller bearings
The bearing has a small contact area (electric contact for ball bearings and line contact for roller bearings), low friction coefficient, low heat generation, less wear, and good accuracy retention; it is suitable for operation at higher speeds.
