CSF Type Cross Roller Bearing

Harmonic reducer bearing is a kind of matching bearing which is focused on harmonic reducer. Harmonic reducer bearings are mainly composed of two surfaces. Harmonic reducer supporting cross roller bearings, according to its use is divided into the outer ring, the inner ring whole (BCSF/BCSG series) and the outer ring and the inner ring whole (BSHF/BSHG series) two categories. The rolling element is a cylindrical roller, distributed in a 90° vertical arrangement in a V-shaped raceway. This structure enables a single bearing to bear loads in all directions such as axial load, radial load and overturning moment at the same time, and the bearing has high stiffness, rotation accuracy and composite bearing capacity. This type of bearing is compact, bearing with mounting holes, easy for customers to install directly, suitable for various types of harmonic reducer.

Harmonic reducer with its high torque capacity, high rigidity, high positioning accuracy, high rotation accuracy, rate, high stability, ultra-small size, weight and other characteristics, widely used in industrial automation and robot arm joint, humanoid robot, semiconductor liquid crystal production equipment, photovoltaic equipment, optical instruments, precision machine tools and other fields. CSF (G) series harmonic reducer specially designed for HD company harmonic reducer, the product inner and outer rings are designed with multiple layers of precision holes can be directly connected with the product work department, the bearing itself has high precision, compact structure, good sealing, strong bearing capacity, high rigidity, stable quality, scientific and reasonable, praised by customers!

Harmonic drive is a comparison of other power transmission mode, with the general transmission mode incomparable performance, large transmission ratio, high precision, large carrying capacity, high efficiency, small size, light weight and many other advantages, widely used in space technology, electronics industry, military industry, robotics, packaging machinery, printing machinery, medical equipment and other fields, with a wide range of applications. We are generally referred to as harmonic reducer or harmonic reducer.

After decades of development, the development of harmonic reducer is also changing with each passing day, harmonic drive technology is becoming mature, as one of the main components of harmonic drive cross roller bearings in recent years in China has also been rapid development. Cross roller bearings are slightly different from ordinary cross roller bearings in structure, the basic structure is similar, basically using the outer ring split type, the inner ring overall structure, compared with standard cross roller bearings, there are many mounting holes on the inner and outer rings, especially the inner ring, from outside to inside there are generally three layers of different size and number of mounting thread holes, This is different in appearance from the basic type cross roller bearing. The material is made of GCr15 bearing steel, the outer ring heat treatment adopts the integral quenching process, and the inner ring adopts the raceway surface high-frequency quenching process, which is the difference compared with the ordinary cross roller bearing process.

 And rely on the continuous optimization of innovation, to achieve the goal of mass production. 

CSF(G) type harmonic reducer bearing:

The overall structure of the inner ring, the outer ring is divided into two pieces, the installation does not need flange and bearing seat, direct installation connection, easy to use, suitable for CSF(G) various harmonic reducer series. CSF(G) series harmonic reducer bearing models are as follows:
