ZARN Needle roller/thrust cylindrical roller bearings use a combination of needleroller bearings with thickened outer rings and two rows of thrust cylindricalroller bearings, which can withstand greater radialaxial loads and have higherradialaxial rigidity. The inner ring, outer ring and cylindrical roller are matchedwith the cage assembly so that a given axial preload can be applied to thebearing using a precision lock nut. These bearings have two types: with orwithout mounting holes in the outer ring.The bearing with holes is directlymounted on the adjacent structure by bolts, the contact surface is large andthe pitch of holes is small, so its rigidity with the adjacent structure is high andwell fixed, and the original bearing end cover mating parts needed to fix thebearing can be saved.

lf the axial adjacent space of the shaft ring is insufficient or needs to be sealed,the bearing with an extended stepped shaft ring can be selected.
