Product Description Product Description UJK Angular Contact Ball Bearings: Precision Performance for Combined Loads and RigidityUJK Angular Contact Ball Bearings are engineered to deliver high-speed operation, exceptional rigidity, and reliable performance in applications demanding precise control over axial and radial loads. Their unique internal design enables them to efficiently handle combined loads where thrust forces are predominant, making them indispensable in precision machinery and high-performance systems.Key Features & Advantages:Optimized for Combined Loads: Features raceways offset in the bearing axis, creating a specific contact angle (typically 15°, 25°, or 40°). This design enables superior handling of simultaneous radial and axial (thrust) loads in one direction.High Axial Load Capacity & Rigidity: Significantly higher axial load capacity compared to deep groove ball bearings. The contact angle provides increased system stiffness, minimizing deflection under load for enhanced precision.High-Speed Capability: Precision-ground balls and raceways, optimized internal geometry, and options for specialized cages (e.g., phenolic resin, machined brass) ensure smooth operation, low friction, and suitability for high rotational speeds.Precision & Accuracy: Manufactured to tight tolerances (ABEC P5, P4, or higher available), ensuring consistent running accuracy essential for applications like spindles and robotics.Preload Options: Can be mounted with controlled preload (axial displacement) to eliminate internal clearance, further increasing system rigidity, reducing noise/vibration, and enhancing positional accuracy.Mounting Flexibility: Available in single-row configurations (requiring paired mounting - DB, DF, DT) or as pre-set matched pairs (duplex) and double-row units for simplified installation and optimized performance.Versatile Configurations: Standard series include 7000C (15°), 7200B/7300B (40°), and variants with different cage materials, shields, or seals for specific environmental or lubrication needs.Ideal Applications:Machine Tool Spindles: CNC machining centers, lathes, grinders (high speed, rigidity, precision).Gearboxes & Transmissions: Especially where significant thrust loads are present.Pumps & Compressors: Handling axial thrust loads.Robotics & Automation: Precision joints, rotary actuators.Electric Motors: High-speed spindles, traction motors.Aerospace Components: Actuators, auxiliary systems.Material Handling: High-speed conveyor drives.UJK Commitment to Quality & Performance:UJK Angular Contact Ball Bearings are manufactured using premium bearing steel and subjected to rigorous heat treatment and precision grinding processes. Stringent quality control ensures dimensional accuracy, reliability, and long service life even under demanding operating conditions. They are designed to meet international standards and specific application requirements.Choose UJK Angular Contact Ball Bearings For:Superior Axial Load Handling: When thrust forces are significant and directional.Enhanced System Rigidity: Minimizing deflection for precision operation.High-Speed Performance: Smooth, efficient rotation at elevated RPMs.Precision Positioning: Critical in robotics, automation, and machine tools.Reliable Operation: Engineered for demanding industrial environments. Why this introduction is effective:Clear Differentiation: Immediately distinguishes them from radial bearings by emphasizing angular contact and combined loads.Core Value Proposition: Focuses on axial load capacity, rigidity, and precision as primary benefits.Technical Specificity: Includes key technical terms: contact angle (15°/25°/40°), preload, paired mounting (DB/DF/DT), duplex, ABEC grades, and standard series (7000C, 7200B, 7300B).Benefit-Oriented: Explains why features matter (e.g., "contact angle provides increased system stiffness... for enhanced precision").Targeted Applications: Lists precision and high-performance sectors where these bearings excel (Machine Tools, Robotics, Aerospace).Quality Assurance: Reinforces UJK's commitment to standards, materials, and manufacturing excellence.Strong Call to Action: Summarizes the key reasons to choose UJK ACBBs.Professional Tone: Suitable for technical documentation, catalogs, websites, and engineering specifications.Key Distinction from Previous Bearings:vs. Self-Aligning Ball Bearings: ACBBs are designed for precision combined loads and rigidity, not misalignment compensation. Misalignment tolerance is very low. They handle much higher axial loads.vs. Spherical Roller Bearings: ACBBs are for high speeds and precision applications with heavy axial components, not primarily for extreme radial loads in harsh environments. They offer lower friction and higher RPM capability.vs. Deep Groove Ball Bearings: ACBBs offer significantly higher axial load capacity and rigidity due to the defined contact angle.
