Product Description RB2008-RB1250110 Series Crossed Roller Bearings: Versatile Precision for Industrial Motion SystemsProduct OverviewThe RB2008-RB1250110 Series Crossed Roller Bearings stand as a benchmark for versatility and reliability in the crossed roller bearing category, covering a wide size range (inner diameter from 20mm to 1250mm, outer diameter from 35mm to 1360mm) to meet the diverse needs of industrial machinery. Engineered with a split inner ring (or outer ring, depending on model) and crossed cylindrical rollers arranged at 90°, this series delivers exceptional rotational accuracy, high rigidity, and multi-directional load capacity-making it a go-to solution for applications where space optimization and performance stability are critical.Crafted from premium bearing steel and finished with precision grinding technologies, each bearing in the RB2008-RB1250110 series undergoes rigorous quality testing to ensure consistent performance in harsh industrial environments, such as high vibration, temperature fluctuations, and heavy-load operations. Whether for small-scale automation equipment (fitted with RB2008) or large industrial machinery (equipped with RB1250110), this series bridges the gap between compact design and heavy-duty functionality.Core Features & AdvantagesBroad Size Range for Universal Spanning from the compact RB2008 (inner diameter 20mm, outer diameter 35mm, width 8mm) to the heavy-duty RB1250110 (inner diameter 1250mm, outer diameter 1360mm, width 110mm), the series covers nearly all industrial scenarios-from miniaturized robotic components to large-scale rotary tables. This eliminates the need for sourcing multiple bearing types, simplifying procurement and supply chain management for customers.Exceptional Rotational Accuracy & RigidityThe crossed roller design (rollers arranged at 90°) ensures even load distribution across all contact points, minimizing radial and axial runout (as low as 0.002mm for high-precision models). The split inner/outer ring structure allows for preload adjustment, enhancing rigidity to resist deformation under high torque or moment loads-critical for maintaining positioning accuracy in CNC machines and robotic arms.Multi-Directional Load HandlingUnlike traditional single-direction bearings, the RB2008-RB1250110 series efficiently handles radial loads, axial loads (both directions), and moment loads simultaneously. For example, the RB1250110 can withstand dynamic radial loads up to 1200kN and moment loads up to 8500kN·m, making it suitable for heavy-duty applications like large-scale rotary tables in steel processing.Durable Construction for Long Service LifeMaterials: Inner/outer rings made of high-purity GCr15 (SUJ2) bearing steel with quenching and tempering treatment (hardness HRC 58-62), ensuring excellent wear resistance and impact strength.Sealing & Lubrication: Optional open, metal shield (ZZ), or rubber seal (2RS) designs; pre-lubricated with high-temperature lithium-based grease, supporting operating temperatures from -40°C to +120°C (standard) and up to +250°C with high-temperature grease.Corrosion Resistance: Custom stainless steel (SS440C) options available for humid or corrosive environments (e.g., food processing, marine equipment).Easy Installation & MaintenanceThe split ring design allows for simple mounting-users can fix the inner/outer ring to the equipment base without disassembling the entire bearing. Additionally, the bearing's standardized mounting dimensions (compatible with ISO standards) ensure interchangeability with other brands, reducing maintenance costs and downtime.Key Application Fields by Size SegmentThe RB2008-RB1250110 series' wide size range enables it to serve diverse industries, with specific models tailored to application scale:1. Small-Size Models (RB2008-RB10025)Inner Diameter: 20mm-100mm | Outer Diameter: 35mm-120mm | Width: 8mm-25mmIndustrial Automation: Miniature robotic joints (e.g., collaborative robot wrists), small conveyor belt rollers, and precision linear stages in 3D printers.Medical Devices: Dental drills, small diagnostic equipment (e.g., blood analyzers), and endoscopic robot components-benefiting from compact size and low vibration.Electronics Manufacturing: Wafer handling arms in small semiconductor packaging machines, PCB drilling machine spindles, and optical sensor adjustment mechanisms.2. Medium-Size Models (RB12030-RB50080)Inner Diameter: 120mm-500mm | Outer Diameter: 145mm-560mm | Width: 30mm-80mmMachine Tools: CNC lathe spindles, precision rotary tables for mold machining, and grinding machine worktables. For example, the RB30050 is widely used in 5-axis CNC machine rotary tables, ensuring sub-micron positioning accuracy.Robotics: Heavy-duty robotic arms (e.g., automotive welding robots), AGV (Automated Guided Vehicle) steering mechanisms, and robotic palletizers-handling moderate loads with high precision.Renewable Energy: Small wind turbine yaw mechanisms, solar panel tracking system rotary joints, and hydroelectric generator auxiliary components.3. Large-Size Models (RB60090-RB1250110)Inner Diameter: 600mm-1250mm | Outer Diameter: 680mm-1360mm | Width: 90mm-110mmHeavy Industry: Large rotary tables in steel rolling mills, mining equipment (e.g., crusher rotating shafts), and port crane slewing mechanisms-withstanding extreme heavy loads and harsh dust conditions.Aerospace & Defense: Radar antenna pedestals, satellite ground station rotary platforms, and aircraft engine test stands-relying on high rigidity and temperature resistance.Infrastructure: Tunnel boring machine (TBM) auxiliary rotating components, large-scale water treatment equipment rotors, and industrial dryer drums.Technical Specifications (Selected Models) Quality Assurance & CertificationsWe adhere to strict international standards to ensure the reliability of the RB2008-RB1250110 series:Certifications: ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), RoHS, REACH, and CE compliance.Testing Protocols:100% dimensional inspection using CMM (Coordinate Measuring Machine) for inner/outer diameter, width, and runout.Load capacity testing (dynamic/static) in accordance with ISO 281.Noise and vibration testing (≤55dB at rated speed) and seal performance testing (IP65/IP67 for sealed models).Traceability: Each bearing is marked with a unique serial number, enabling full traceability from raw material to delivery.Service & SupportCustomization: Offer tailored solutions for non-standard requirements, including:Special materials (stainless steel, ceramic rollers).Coatings (TiN, CrN for wear resistance; PTFE for low friction).Modified mounting structures (flanged, tapped holes).Delivery:Standard models (RB2008-RB50080): 7-15 days lead time.Large models (RB60090-RB1250110): 20-30 days lead time.Global shipping via DHL, FedEx (express) or sea freight (bulk orders), with door-to-door delivery options.Warranty & After-Sales:12-month warranty against manufacturing defects.24/7 technical support (via email, phone, or video call) for installation, maintenance, and troubleshooting.Replacement parts (rollers, seals, cages) available for quick delivery.
