RAU micro cross roller ring Bearings

RAU micro cross roller ring Bearings, RAU type is a compact ring type that reduces the thickness of the inner and outer rings of RB type to the limit. It is particularly suitable for parts that require light weight and compact design, such as the rotating parts of the robot, and can be used in places where the inner and outer rings rotate. The RAU series can achieve lightweight and miniaturization of the device due to its extremely small cross-sectional area. The other two variants are RA type and RA-C type. The three types have the same external dimensions. The difference is that: RA type has an integral inner ring and a split outer ring, which is suitable for parts that require light weight and compact design, and has a high cost performance; RA-C type has a notched structure on the outer ring, and the outer ring also has high rigidity, so it can also be used for outer ring rotation. RAU also has an ultra-thin type with a width of 5mm and an RA type compatible type. The product lineup of the ultra-thin series starts from the ultra-small inner diameter of 10mm.

Crossed roller bearings are designed to bear radial loads, axial loads, moment loads and other loads in all directions because their cylindrical rollers are arranged perpendicularly to each other on the 90° V-groove rolling surface through spacers. The cross roller ring has high rigidity, so it is most suitable for the joints or rotating parts of industrial robots, the rotary table of machining centers, the rotating part of manipulators, precision rotary tables, medical machines, measuring instruments, IC manufacturing devices, etc.

Our company has professional sales and technical engineers who are responsible for providing users with technical consultation, technical services and product technical training on precision bearing data and installation and use. Perfect pre-sales, in-sales and after-sales services constitute a guarantee system for high-quality services, providing users with reliable quality bearing products and creating a good user experience and rich benefits for every customer.
