Product Description
What is cross roller bearing
The cross roller bearing is a compact bearing with an orthogonal roller configuration between the inner ring and the outer ring. Through the cross arrangement of the roller structure, it can play the best role as the bearing supporting the rotation of the robot arm.
The birth of cross roller bearing
Nowadays, from medical robots to welding robots to industrial robots picking up parts, various robots are active everywhere. These robots are developing towards high function, high performance and high quality every day. The bearing that supports the rotation must be able to withstand high speed running and the demanding load produced by complex actions. In addition, in addition to the severe load, there is also a need for precision action. In order to be able to be used safely in the harsh environment of robots, cross-roller bearings emerged.
Why cross roller bearings
1. Compact structure. Through the cross arrangement of rollers, the contact Angle installed is 45 degrees, which helps to save space.
2. High rigidity, the precision performance of the cross roller itself requires that the material of the bearing should conform to the bearing processing technology. Therefore, it has the characteristics of strong rigidity and high hardness.
3. Diversity. The cross roller bearing standard is rich and complete with various products. For machine tools, large robots and general industrial equipment, the CRBH type with integral structure of outer ring and inner ring, and the CRB and CRBC type with two parts of outer ring along the axis are the best choices. Small and medium sized robot joints, semiconductors and other electronic and electrical equipment automatic devices, suitable for the end of small size CRBS. For precision small device, the thin CRBT with small section area is the best choice. The high rigidity CRBF type is also used to simplify the mounting hole attached to the bearing housing structure.
4. Usability. Through the cross arrangement of rollers, a bearing can bear complex loads from all directions at the same time, and the assembly can be independent of the direction of load.
5. Flexibility. Luoyang east shaft bearing is good at multi-type production, including non-standard shape, size and surface treatment. Through research and development to overcome various technical difficulties to produce a variety of special structural size bearings.
6. Quality: luoyang east axis produces rotary table bearings all year round, and accumulated manufacturing and testing experience, which can produce high-precision cross roller bearings stably and reliably.

This catalog allows you to make a rough estimate of bearing choices that will be used in your project work. Whether bearings listed in this catalog are statically assigned to their critical load curve load capacity and service life curves. In order to determine the required capacity, the identified load must be multiplied by. The "load factor" shown in table 1 is applied in different cases except for type 13. There are also 21 collections. If no application is indicated, the comparability factor must be used according to how the operation is performed.
Frequently encountered problems in use:
Friction theory is a well - known term in anti - friction bearing technology. Due to various influencing factors, the theoretical service life of nominal bearing cannot be regarded as absolute in practice, but can be used as reference value and design guide. Not all bearings reach theoretical values. In practice, most people will surpass it, and the theoretical life standard cannot be applied to practice. In particular, for large diameter bearings, bearings perform intermittent rotary motion or slow rotation. In most applications, the speed of rotation will be relatively low in competition. Therefore, smooth operation, accurate running of bearings are not affected by wear and tear. There were sporadic flecks of hemp. Therefore, it is rare to design large diameter bearings for turning or decelerating. Rotational motion is carried out on the basis of theory. In life, give a better definition. When the bearing has started to work, the service life of the bearing increases when the torque resistance increases gradually, or when the wear phenomenon occurs and develops until now, the function damage of the bearing. The operating conditions of highly diversified bearing with large diameter are adopted. The operation of the mode is completely different, for example, the rotation Angle is different and the operation is different. Periodic, oscillating motion or continuous rotation. Therefore, in addition to the static aspect, these dynamic effects must be considered.
