CRBF High Rigidity Crossed Roller Bearings with Mounting Holes

The inner and outer rings of the CRBF high-rigidity cross roller bearing with mounting holes are both one-piece structures, and the mounting holes on the inner and outer rings can be easily installed in the device. In addition, it is not easily affected by surrounding structures such as the bearing seat and pressure plate, and achieves high-rigidity and high-precision guidance. The inner and outer rings adopt an integral structure to prevent installation errors. In addition, since it is equipped with mounting holes that can be directly fixed on the other party's mounting surface, the structure and accuracy of the bearing seat are not affected, and high-rigidity and high-precision guidance can be easily achieved. It can be easily installed in the device without a bearing seat and a pressure plate, and it can be easily fixed with bolts, so that the surrounding area of the bearing can be designed more compactly. This can reduce the number of parts and assembly processes, which helps to produce small and lightweight devices.

Crossed roller bearings are compact bearings with rollers arranged orthogonally between the inner and outer rings. The rolling surfaces are in line contact, so the elastic displacement caused by the bearing load is extremely small, and it can simultaneously carry complex loads such as radial loads, axial loads, and torque. This type of bearing is widely used in rotating parts of industrial robots, machine tools, and medical equipment that require small, high rigidity and high rotation accuracy.

Common types include standard cross roller bearings, ultra-thin cross roller bearings, thin cross roller bearings, high rigidity cross roller bearings, and high rigidity cross roller bearings with mounting holes. Crossed roller bearings are available in types with cages, separators, and full rollers. Cages and separators are suitable for parts with low friction coefficients and high speeds, while full rollers are suitable for parts with low speeds and heavy loads.

Crossed roller shafts are available in open and sealed types. The sealed type has a special synthetic rubber sealing gasket installed on the side of the bearing, which has an excellent sealing effect for dust and grease leakage. However, excess grease may be discharged during initial operation. The operating temperature range of cross roller bearings is -20 to 120°C. However, the maximum allowable temperature of the models with separators and seals is 110℃, and 100℃ for continuous operation. Our company also manufactures stainless steel cross roller bearings, please contact MONTON.

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, creating a good user experience and rich benefits for every customer.

If you have any questions about products and services, please contact the company's service department directly.
