ZARN series ---Ball screw support bearings Needle roller/thrust cylindrical roller bearings
With the development of machine tool equipment technology, high precision and high efficiency have become the important technical features of the machine tool industry. The ball screw bearing of machine tool has gradually abandoned the traditional structure mode of paired contact ball, instead, needle roller/thrust cylindrical roller bearings are adopted.
Needle roller/thrust cylindrical roller bearings adopt the combination structure of needle roller bearings with thickened outer ring and two rows of thrust cylindrical roller bearings, which can bear more radial/axial load and have higher radial/axial rigidity, at the same time, the series of bearing axial run-out accuracy can reach 1 m, especially in line with the current machining industry requirements of high precision, high load-bearing, high efficiency.
Product Features:
1.Needle roller/thrust cylindrical roller bearings include a thickened outer ring, Needle Roller Retainer Assembly, needle roller inner ring, two thrust cylindrical roller retainer assemblies, and two thrust shaft rings, equivalent to a set of needle roller bearings and two sets of thrust cylindrical roller bearings combination bearing, two thrust cylindrical roller bearing center and Needle Roller Bearing Center coincidence;
2.Needle roller/thrust cylindrical roller bearings can bear axial force, radial force and overturning moment in two directions;
3.Needle roller/thrust cylindrical roller bearings can be divided into two series: Bolted and non-bolted.
