INA ZARF35110-TV Nadel-Axialzylinderrollenlager (35x110x66)

As a combined needle/thrust bearing, this bearing carries radial and axial loads simultaneously. For this INA bearing, 35x110x66 mm and a weight of 1.927 kg apply; the specification table holds the further technical particulars. Two rolling element sets in one assembly: a needle roller assembly for the radial load and an axial cylindrical roller set for the longitudinal one.

The combined needle roller / axial cylindrical roller bearing unites two rolling element sets in one assembly: the needle roller assembly takes the radial load, the axially arranged cylindrical roller set the longitudinal force. Because both directions carry over rollers and therefore over line contact, the unit reaches a high capacity in both axes within a small envelope and replaces two individual bearings arranged in series.

The ratings apply separately: the radial rating describes the needle set, the axial one the roller set, and neither value supports the other direction. Depending on the version, supplied washers provide the raceways or the surrounding design does; in the latter case the mating faces are to be hardened, ground and made square to the axis. As with every axial roller set, sliding occurs along the roller length, so speed, lubricant supply and heat dissipation must be considered together. Standard bearing steel is through-hardened and covers the usual operating-temperature range.
