Moment Stiffnessrb Duracarb Series: Carburized Steel Crossed Roller Bearings for Extreme Service Life. High Rotational Accuracy: 90-degree crossed rollers with spacers prevent tilting, ensuring high precision and stable motion under preload. Ultra-Thin Compact Design: Minimized inner and outer ring dimensions save installation space while maintaining high strength and rigidity. Multi-Directional Load Capacity: V-grooved design withstands significant radial, axial, and moment loads simultaneously. Carburized Steel Construction: Provides excellent impact resistance and surface wear resistance for extreme service life. Easy Installation: Split ring structure allows straightforward assembly of rollers and spacers before fixing the rings. Adjustable Clearance: Split structure enables clearance adjustment for optimized stiffness and guidance accuracy. Low Inertia & Torque: Nylon spacers offer low moment of inertia and low starting torque for easy angular indexing control. Wide Application Range: Ideal for industrial robots, machining centers, medical equipment, and precision rotary tables.
