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.
Automated packaging and filling equipments are full-automatic production machines widely used in food,beverage,pharmaceutical,cosmetic,chemical and daily necessities industries,including rotary filling machines,rotary pouch packaging machines,capsule filling lines,bottle capping turntables,multi-station indexing packaging machines and weighing rotary platforms.These devices rely servo-driven rotary turntables and swing manipulators to complete continuous procedures such as bottle feeding,quantitative filling,bag clamping,sealing,capping,weighing and finished product discharging in cyclic indexing motion.The central rotary base,indexing turntable and swing manipulator spindles of filling & packaging machines are pre-installed with servo motors and reducers before bearing assembly.During long-cycle mass production,rotary structures run with frequent start-stop,intermittent indexing and reciprocating swing,bearing combined loads including turntable self-weight,clamping mechanism tension and unbalanced material overturning moment.Production workshops often have dust,powder splashing,water mist and occasional chemical liquid splashes,which impose strict demands on bearings for stable rotation,repeated positioning accuracy,dust-proof and corrosion resistance.Any slight bearing jitter or positioning deviation will cause inaccurate filling volume,bag misalignment and defective sealing,directly reducing product yield and production line efficiency.
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 Rotary Turntable Assembly & Line Debugging:The integral RU bearing with reserved mounting holes can be directly bolted to the central turntable frame of filling and packaging machines without extra bearing seats and auxiliary flanges.It can be installed on pre-assembled servo spindles and reducers without dismounting transmission components,greatly shortening equipment assembly and on-site production line debugging cycles.
Bear Composite Dynamic Loads of Multi-Station Rotary Platforms:A single RU bearing replaces multiple sets of ordinary bearings to simultaneously bear the turntable dead weight,clamping fixture tension and unbalanced material overturning torque generated during high-speed cyclic indexing.Uniform force distribution avoids spindle micro-deformation during long-hour continuous production,maintaining consistent station positioning and stable filling precision.
Ensure Stable Filling & Packaging Precision:Preloaded ultra-high rigidity effectively suppresses micro-vibration during intermittent rotation and frequent start-stop movements.Ultra-low rotational runout eliminates station offset,inaccurate metering and sealing defects caused by slight shaking,stabilizing filling volume consistency and packaging forming quality for food and pharmaceutical products.
Adapt Compact Production Line Layout:Ultra-thin cross-section reduces the overall height and rotary inertia of central indexing turntables,making packaging machines more compact and floor-space-saving.Fast dynamic response improves indexing switching speed,supporting high-frequency continuous packaging and filling operations to boost line output.
Adapt Dust & Splash Workshop Environments:U/UU double rubber sealing blocks powder,water mist and liquid splashes from filling workshops; SUS440C stainless steel customized RU bearings resist weak acid/alkali detergent corrosion for pharmaceutical and food hygiene production lines,protecting internal rolling elements from contamination.
Lower Long-Term Production Line Downtime:Hardened bearing raceways and rollers deliver excellent anti-fatigue performance under 24-hour non-stop cyclic operation.Stable long-term precision reduces regular bearing replacement and equipment shutdown maintenance,raising the overall utilization rate of automated packaging & filling production lines.
