NKXR 30 ZCombined needle roller / cylindrical roller thrust bearing with a cover

SKU: NKXR 30 ZCombined needle roller / cylindrical roller thrust bearing with a cover

These bearings consist of a radial needle roller bearing combined with a cylindrical roller thrust bearing. Together they can accommodate both radial loads and axial loads in one direction. Their low cross-sectional height makes the bearings particularly suitable for applications where other types of locating bearing arrangements occupy too much space. The thrust part is capped with a cover that forms a gap-type seal to retain the grease in the bearings.
