“…Because needle roller bearings have a line contact which increases the rigidity and maximum load capacity of the universal joint while the ball bearings have a single point contact which limits the strength [5]. Additionally, the needle roller is the one suitable rolling element for the universal joints when considered that the internal space of the bearing is limited [6].…”

The presence of the oscillating motion in a mechanical system, is vital in terms of the service life. Because the machine elements are under effect of fatigue due to the oscillating motion. The service life of the bearings which are in the forefront among the machine elements subjected to oscillating motion, can be calculated via an equation that depends on several variables, one of which is basic dynamic load rating (C). In this context, basic dynamic load rating (C) is one of the most important factors on estimating the service life. One of where bearing applications used in, is universal joint of driveshaft. A bearing on a universal joint consists of needle roller elements having larger contact area compared to the ball elements. Universal joint bearing is mounted in a bore on a component called yoke part, and so yoke part supports the bearing. In the calculation of basic dynamic load rating for universal joint bearing, effective length of the rolling element is the key factor. In this paper, a new approach to determine the effective length of rolling element used in closed end needle roller bearings of driveshaft has been investigated analytically and the effect of the said approach on the basic dynamic load rating and bearing life has been revealed in terms of ISO 281.
