NTN complex bearing is comprised of a needle roller bearing of supporting radial load and a thrust bearing for supporting axial load which are assembled integrally. 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.

The rating life (L) of any complex bearing is determined as follows. Determine individually the rating life (Lr) of radial needle roller bearing from radial load acting thereon and the rating life (La) of thrust bearing from axial load acting thereon. And determine the rating life (L) from these determined rating lives (Lr, La) using the following formula
