CRBH Series Crossed Roller Bearings are a type of precision crossed roller bearing that features an ultra-thin, high-rigidity structure. The CRBH Series is designed for applications where high precision, compactness, and rigidity are critical. These bearings are distinguished by their integrated inner and outer rings, which eliminate the need for a separate flange, allowing for a more compact and space-saving design. The CRBH Series features both inner and outer rings integrated as one unit, reducing the number of parts and simplifying the design. This integration provides a lower profile and higher rigidity compared to standard crossed roller bearings. The inner and outer rings can be directly fixed onto the equipment, simplifying the design and installation process.
