Complex Bearings
NTN complex bearing is composed of a radial needle
roller bearing to support radial load and a thrust ball
bearing or a thrust roller bearing to support axial load
which are integrated into one bearing unit. Comparing
with individual use of a radial bearing and a thrust bearing
for the same purpose, this complex bearing saves the
required installation space and thereby can contribute to
making the overall construction of an equipment more
compact.
