Bearings
High precision fast speed long life.
Needle roller / cylindrical roller thrust bearings combine a radial needle roller bearing and a cylindrical roller thrust bearing based on the 811 series. Supplies these bearings in the following two series:
NKXR series ( fig. 1 ) cylindrical roller thrust bearing is separable
NKXR .. Z series ( fig. 2 ) non-separable bearing
These bearings are supplied without an inner ring. For applications where it is not possible to harden and grind the shaft the bearings can be combined with an inner ring ( fig. 3 ). Appropriate inner rings are listed in the product tables and can be ordered separately.
Needle roller / cylindrical roller thrust bearings NKXR .. Z series
Needle roller / cylindrical roller thrust bearings in the NKXR .. Z series ( fig. 2 ) are nonseparable. They have a stamped steel cover that extends over the shaft washer of the cylindrical roller thrust bearing. It is firmly attached to the housing washer that is integral to the needle roller bearing outer ring. The cover makes these bearings non-separable.Supplies the cylindrical roller thrust bearing in this series filled as standard with a high-quality grease that has good rust inhibiting properties. The cover which has no lubrication holes forms a gap-type seal with the shaft washer to retain the grease in the bearing.
