Introduction to needle roller/thrust cylindrical roller bearings

With the development of machine tool equipment technology, high precision and high efficiency have become important technical features of the current machinery industry. The ball screw bearing of the machine tool gradually abandons the structural mode of the traditional paired angular contact ball, and instead uses the needle roller/thrust cylindrical roller. The structural form of the bearing.(HONBBEARING02)

Needle roller/thrust cylindrical roller bearings have a combination of thickened needle roller bearings and two rows of thrust cylindrical roller bearings to withstand greater radial/axial loads and higher radial/axial Rigidity, the axial runout accuracy of this series of bearings can reach 1μm, which is especially in line with the high precision, high load bearing and high efficiency required by the current machining industry.

Product Features

Needle roller/thrust cylindrical roller bearings include a thickened outer ring, needle retainer assembly, needle inner ring, two thrust cylindrical roller cage assemblies and two inferential shaft rings, equivalent to a set of needle bearings Combined with two sets of thrust cylindrical roller bearings, the center of the two thrust cylindrical roller bearings and the center of the needle bearing coincide.

Needle roller/thrust cylindrical roller bearings can withstand axial, radial and overturning moments in both directions.

Needle roller/thrust cylindrical roller bearings can be divided into two types: bolted and non-bolted according to the difference in the way the outer ring is installed.
