Product Description XV Series Crossed Roller Bearings: Precision Engineered for High-Performance Industrial ApplicationsProduct OverviewThe XV Series Crossed Roller Bearings represent the pinnacle of precision bearing technology, designed to deliver exceptional rigidity, high load-carrying capacity, and ultra-precise rotation in compact structural designs. Engineered with advanced manufacturing processes and premium materials, these bearings are tailored to meet the rigorous demands of modern industrial machinery, ensuring long-term reliability and consistent performance even in harsh operating environments.Ideal for applications requiring tight radial and axial runout control, the XV Series eliminates the need for multiple bearing assemblies, reducing overall equipment size while enhancing operational efficiency. Whether for robotic joints, precision machine tools, or medical imaging equipment, these bearings set a new standard for accuracy and durability in critical motion systems.Core Features & AdvantagesSuperior Precision & RigidityConstructed with crossed cylindrical rollers arranged at 90° angles, the XV Series achieves minimal radial and axial runout (as low as 0.001mm). This design distributes loads evenly across all rollers, delivering exceptional rigidity to resist deformation under high torque or heavy loads-critical for maintaining positioning accuracy in precision machinery.High Load-Carrying CapacityThe unique crossed roller configuration enables the bearing to handle radial, axial, and moment loads simultaneously. Compared to traditional ball bearings, it offers 30-50% higher radial load capacity and 5-10x greater moment load resistance, making it suitable for heavy-duty applications like machine tool spindles and robotic arms.Compact & Space-Saving DesignBy integrating radial and axial load support into a single unit, the XV Series reduces the required installation space by up to 40% compared to combined bearing systems. This compactness is a game-changer for miniaturized equipment (e.g., semiconductor handling robots, medical devices) where space is at a premium.Low Friction & Long Service LifePrecision-ground rollers and raceways, paired with high-quality lubricants, minimize friction and wear. The bearing's sealed structure (optional IP65/IP67 ratings) prevents contamination from dust, liquids, and debris, extending service life to 10,000+ operating hours in typical industrial conditions.Customizable ConfigurationsAvailable in multiple sizes (inner diameter: 15mm - 500mm), accuracy classes (P0, P6, P5, P4), and mounting types (flanged, cylindrical, split inner/outer ring). Custom designs (e.g., special materials, coatings, or sealing options) are also offered to meet specific application requirements.Key Application FieldsThe XV Series Crossed Roller Bearings are widely adopted across industries that demand precision, reliability, and compactness:Industrial RoboticsEssential for robotic joints (shoulder, elbow, wrist), rotating bases, and end-effectors. Ensures smooth, precise motion control for pick-and-place robots, collaborative robots (cobots), and assembly line robots, improving production efficiency and product quality.Machine ToolsUsed in CNC machine tool spindles, precision rotary tables, and linear guides. Delivers the rigidity and accuracy needed for high-speed milling, grinding, and boring operations, reducing machining errors and enhancing surface finish of workpieces.Medical EquipmentCritical for CT scanners, MRI machines, and surgical robots. The bearing's high precision and low vibration ensure clear imaging results and stable surgical movements, while its cleanroom-compatible design meets strict medical hygiene standards.Semiconductor ManufacturingIdeal for wafer handling robots, lithography equipment, and inspection platforms. Enables sub-micron positioning accuracy required for semiconductor wafer processing, ensuring the integrity of microchip production.Automotive & TransportationApplied in electric vehicle (EV) powertrains, steering systems, and automated guided vehicles (AGVs). Withstands high temperatures and vibration, supporting the reliability of next-generation automotive technologies.Aerospace & DefenseUsed in satellite antennas, radar systems, and aircraft landing gear components. The bearing's high strength-to-weight ratio and resistance to extreme temperatures make it suitable for aerospace-grade applications.Technical Specifications (Standard Model)ParameterSpecificationInner Diameter (d)15mm - 500mm (custom sizes available)Outer Diameter (D)35mm - 600mmWidth (B)8mm - 80mmAccuracy ClassP0, P6, P5, P4 (per ISO 492)Radial ClearanceC2, C0, C3, C4, C5Rated Dynamic Load (Cr)5.2kN - 580kNRated Static Load (Cor)8.5kN - 920kNMaximum Rotational Speed3,000 - 8,000 rpm (depending on size)Operating Temperature-40°C to +120°C (standard); -150°C to +250°C (high-temperature option)Sealing OptionOpen, ZZ (metal shield), 2RS (rubber seal), IP65/IP67MaterialInner/Outer Ring: GCr15 (SUJ2); Rollers: GCr15; Cage: Polyamide (PA66) or BrassQuality Assurance & CertificationsWe adhere to strict quality control standards throughout the manufacturing process, from raw material selection to final inspection:Certifications: ISO 9001:2015, ISO 14001:2015, RoHS, REACH compliant.Testing: 100% dimensional inspection (using coordinate measuring machines - CMM), load capacity testing, and noise/vibration analysis.Raw Materials: High-purity bearing steel (GCr15/SUJ2) sourced from certified suppliers, ensuring consistent material performance.Service & SupportCustomization: We offer tailored solutions for non-standard sizes, materials (e.g., stainless steel for corrosion resistance), and special coatings (e.g., TiN for wear resistance).Delivery: Fast lead times (7-15 days for standard models; 30-45 days for custom orders) with global shipping via DHL, FedEx, or sea freight.Warranty: 12-month warranty against manufacturing defects, with technical support available 24/7.After-Sales: Professional after-sales team to assist with installation guidance, maintenance advice, and replacement parts.
