Harmonic reducer bearings are a type of matching bearing specifically designed for harmonic reducers. Harmonic reducer bearings mainly consist of two surfaces. Harmonic reducers are equipped with crossed roller bearings, which are divided into two categories according to their usage scenarios: outer ring split, inner ring integral (BCSF/BSCG series), and outer ring and inner ring integral (BSHF/BSHG series). The rolling elements are cylindrical rollers arranged vertically at a 90 ° angle in a V-shaped raceway. This structure allows a single bearing to simultaneously withstand loads in various directions such as axial load, radial load, and overturning moment. The bearing has high stiffness, rotational accuracy, and composite load-bearing capacity; This type of bearing has a compact appearance and comes with mounting holes, making it easy for customers to install directly. It is suitable for various types of harmonic reducers.

Harmonic reducers are widely used in various fields such as industrial automation, robot arm joints, humanoid robots, semiconductor LCD production devices, photovoltaic equipment, optical instruments, precision machine tools, etc. due to their high torque capacity, high rigidity, high positioning accuracy, high rotation accuracy, rate, high stability, ultra small size, and weight. The CSF (G) series harmonic reducer is designed with crossed roller bearings for HD company's harmonic reducer. The inner and outer rings of the product are designed with multiple layers of precision holes that can be directly connected to the working part of the product. The bearings themselves have high precision, compact structure, good sealing, strong load-bearing capacity, high rigidity, stable quality, scientific rationality, and have been well received by customers!

Harmonic drive is a type of power transmission that has many advantages over other transmission methods, such as high transmission ratio, high precision, large load-bearing capacity, high efficiency, small size, and light weight. It is widely used in space technology, electronics industry, military industry, robotics, packaging machinery, printing machinery, medical equipment, and other fields, and has a wide range of application space. We generally refer to it as harmonic reducer or harmonic reducer.

After decades of development, the development of harmonic reducers has also been advancing rapidly, and harmonic transmission technology has become increasingly mature. As one of the main components of harmonic transmission, cross roller bearings have also experienced rapid development in China in recent years. Harmonic drive special cross roller bearings have slightly different structures from ordinary cross roller bearings. The basic structural form is similar, basically using an outer ring segmentation type and an inner ring integral structure. Compared with standard cross roller bearings, there are many installation holes machined on the inner and outer rings, especially the inner ring, which generally has three layers of installation threaded holes of different sizes and quantities from the outside to the inside. This is the difference in appearance from basic cross roller bearings. The material is made of GCr15 bearing steel, and the outer ring is heat-treated with integral quenching process, while the inner ring is heat-treated with high-frequency quenching process on the raceway surface, which is the difference compared to the ordinary cross roller bearing process.

Luoyang ONA Bearing Co., Ltd. (ONA), as a dedicated cross roller bearing manufacturer in Chinese Mainland, relies on years of profound accumulation in cross roller bearing research and development and production, absorbs foreign experience and technology in cross roller bearing, refines product series, develops and produces a full range of cross roller bearing products in harmonic drive, and achieves the goal of mass production by constantly optimizing and creating. This product not only replaces similar products imported from abroad in Chinese Mainland and Taiwan, but also goes abroad and exports its products to the United States, Japan and other countries, becoming a major supplier of cross roller bearings for harmonic drive and a main supplier and partner of many manufacturers in the field of harmonic drive.
