Product introduction:

NRXT9020DDC8P5 belongs to to the N series (NRXT-) crossed roller bearings. This series of bearings are thin-walled bearings with the characteristics of high rigidity, high precision, and lightweight. NRXT-crossed roller bearings have two halves in the outer ring and a one-piece inner ring. They are particularly suitable for applications that require high rotation accuracy of the inner ring.

Technical data of the NRXT9020DDC8P5 cross roller bearing

Features:

It has excellent rotation accuracy. The internal structure of the crossed roller bearing uses rollers arranged perpendicularly at 90° to each other (this is also the origin of the name of the crossed roller bearing). There are spacers or isolation blocks between the rollers, which can prevent the rollers from tilting or rubbing against each other, effectively preventing the increase in rotational torque. This crossed cylindrical roller bearing has been included in Kuaiyou. In addition, there will be no contact or locking of one roller. At the same time, because the inner and outer rings of standard crossed roller bearings have a divided structure, the gap can be adjusted even if it is High-precision rotational motion that can also be obtained by applying pre-pressure.
Simplified operation and installation. Standard crossed roller bearings are divided into two parts the outer ring and the inner ring. After the rollers and cages are installed, they are fixed together. During installation, the connecting bolts and fixing flanges can be fine-tuned. Reach the ideal load state, so the installation operation is very simple.
Bear large axial and radial loads. Because the rollers are arranged vertically to each other through spacers on the 90° V-groove rolling surface, this design allows the crossed roller bearing to withstand larger loads. Loads in all directions such as radial load, axial load, and moment load.
Significantly save installation space. The dimensions of the inner and outer rings of crossed roller bearings are minimized especially the ultra-thin structure. This type is small in size close to the limit and has high rigidity, so it is most suitable for joints with industrial robots. Or rotating parts, rotary tables of machining centers, robot rotating parts, precision rotary tables, medical instruments, measuring instruments, IC manufacturing equipment, etc.

Applications:

Precision rotary indexing tables for machine tools, vertical and horizontal boring machines, vertical grinders, rotary surface grinders, large gear hobbing machines, gun and radar rotary tables, large radio and optical telescopes, rotary cameras, steering pivots and continuous casting machines, Height-limited pivot microscope stages, rod center pivots, rotating bogies, welding brackets, rotating assembly fixtures, industrial robots, precision rotating tables, medical equipment, measuring instruments, and IC manufacturing equipment.
