Ultra-Thin Section Design: This is the most notable feature of the XV Series. Its extremely narrow cross-section means the bearing can operate in very confined spaces, making it ideal for equipment requiring miniaturization and lightweighting. For example, in industrial robots, medical devices, and semiconductor manufacturing equipment, the XV Series effectively reduces overall size and weight without sacrificing performance.
High Precision and High Rigidity: By integrating crossed cylindrical rollers into a compact inner and outer ring, the XV Series can simultaneously withstand radial, axial, and tilting moment loads. This unique structure of crossed roller bearings ensures extremely high rotational accuracy and rigidity, making it particularly suitable for applications requiring precise motion control, such as precision rotary tables, measuring instruments, and CNC machine tools.
Easy Installation and Space Savings: The XV Series's one-piece construction makes installation exceptionally simple, eliminating the need for complex preloading or adjustments. Its ultra-thin design not only saves valuable installation space but also simplifies the design of surrounding mechanical structures, reducing overall manufacturing costs.
Wide Range of Sizes and Customization: We offer ultra-thin XV series crossed cylindrical roller bearings in a variety of sizes and models to meet the specific needs of diverse customers. Whether your application requires specialized inner or outer diameters, we can provide the most suitable solution. We also offer specialized customization services to ensure the bearings perfectly meet your unique design specifications.
Industrial Robot Joints: The ultra-thin design and high rigidity make them ideal for robotic joints, enabling precise and smooth motion.
Medical Equipment: Medical devices such as CT scanners and MRI machines require high precision and lightweight design.
Semiconductor Manufacturing Equipment: In wafer processing and inspection equipment, the XV series' high precision ensures reliable production processes.
Precision Measuring Instruments: Optical measuring stages and coordinate measuring machines, for example, require extremely high rotational accuracy.
CNC Machine Tools and Machining Centers: They provide excellent rigidity and rotational accuracy in precision rotary tables and spindles.
