Precision RU Crossed Roller Bearings are compact,high-rigidity rotational bearings featuring cylindrical rollers arranged at 90° angles in a V-groove.Unlike traditional bearings,their unique cross-pattern allows a single bearing to simultaneously handle complex multi-directional loads-including radial,axial,and moment (tilting) forces.These bearings are available in P5,P4 and P2 precision grades.The inner diameter ranges from 10mm to 350mm,the outer diameter from 52mm to 540mm,and the cross-section height varies between 8mm and 45mm.The mounting holes support specifications from M3 to M12.For materials,bearing rings and rollers are made of GCr15 high-carbon chromium steel with a surface hardness of HRC 60-62,or corrosion-resistant SUS440C stainless steel.Nylon 66 or high-strength brass is selected as the cage material.Two main sealing types are provided:open type for clean working environments and U/UU contact rubber seal for dust and splash resistance.In terms of lubrication,both standard grease lubrication and circulating oil lubrication for heavy-duty use are available.Standard RU models can be delivered within 7-15 days,while customized products will be scheduled according to specific technical requirements.
Delta parallel robots and industrial handling robots are core automated equipment widely used in food,pharmaceuticals,electronics,logistics and other industries.Delta parallel robots,also known as spider robots,adopt a parallel link structure composed of a static platform,moving platform and multiple connecting rods.They excel at ultra-high speed,high repeat positioning accuracy and low motion inertia,and are mainly used for high-frequency sorting,picking and packaging of light and small workpieces.Industrial handling robots cover multiple types such as articulated robots and gantry robots.They undertake tasks like material transferring,loading and unloading,and palletizing.The rotary joints and central rotating platforms of both types of robots are usually equipped with gears and reducers on the main shaft in advance.The rotary parts need to operate continuously with frequent start-stop,swing and indexing movements,and bear alternating dynamic loads.Meanwhile,workshop environments often contain dust,debris and humidity,which set strict requirements on the load capacity,rotational precision,structural rigidity,low noise and environmental adaptability of supporting bearings.The performance of rotary bearings directly determines the running speed,operation stability and service life of the entire robot system.
Multi-Directional Load Capacity:Because the cylindrical rollers are alternately crossed at right angles,a single bearing can support radial,axial,and tilting moment loads at the same time.
Integrated Mounting Design:Unlike traditional bearings,RU series inner and outer rings are fully integrated.They include pre-drilled mounting holes,eliminating the need for a separate presser flange or fixing housing.
High Rigidity and Accuracy:Bearings are preloaded,minimizing elastic deformation under heavy loads and ensuring high running accuracy (often up to P5,P4,or P2 grades).
Space and Weight Efficiency:By consolidating multiple bearings into a single compact unit,equipment size and weight can be significantly reduced.
Stable Rotational Torque:Equipped with spacer retainers between the rollers,they offer a low friction coefficient,resulting in highly stable,smooth rotational torque.
Industrial Robotics:Found in basic motion parts such as robot waists,elbows,and rotary joints.Their rigidity allows them to support heavy moment loads at high speeds.
Precision Machine Tools:Utilized in rotary tables,index heads,and spindles for CNC machines and machining centers.
Semiconductor Fabrication:Provide the micron-scale accuracy required for wafer transfer robot arms,photolithography machines,and precise rotary indexing.
Medical & Lab Equipment:Built into rotating parts of advanced diagnostic tools like CT scanners,MRI machines,and robotic surgery components.
Optical & Measuring Instruments:Employed in high-precision astronomical telescopes,CMM (Coordinate Measuring Machines) rotary tables,and laser measuring devices.
Simplify Modular Assembly & Maintenance:The integral body with prefabricated mounting holes can be directly bolted to robot structural parts.It can be installed on pre-assembled spindles with gears and reducers without dismounting existing components,shortening the robot assembly cycle and reducing production and after-sales maintenance costs.
Withstand Complex Dynamic Loads:A single RU bearing replaces multiple traditional bearing sets to synchronously bear the robot's self-weight,workpiece payload and swing overturning moment.The reasonable force distribution prevents structural deformation and improves the overall stability of robotic moving parts.
Ensure High-Speed & Precise Operation:Ultra-low rotational runout and high rigidity effectively restrain micro-jitter during high-speed movement.It maintains consistent repeat positioning accuracy,preventing picking deviation and workpiece damage,and guaranteeing the stable operation of high-frequency sorting and handling tasks.
Adapt to Compact Structural Layout:The ultra-thin and lightweight profile reduces the motion inertia of robotic arms and moving platforms,further improving the dynamic response speed and operational flexibility of Delta and handling robots.
Adapt to Various Working Environments:Rubber sealing options block workshop dust and debris.Stainless steel material and special lubricants can be selected for humid and slightly corrosive environments,protecting internal components and maintaining long-term stable performance.
Reduce Unplanned Downtime:Excellent fatigue resistance and wear resistance support 24-hour uninterrupted operation of automated production lines.It lowers the frequency of bearing replacement and routine maintenance,and improves the overall operational efficiency of workshops.
