RB Crossed Roller Bearings are high-precision components featuring cylindrical rollers arranged at 90°angles in alternating directions.This allows a single bearing to handle radial,axial,and moment loads simultaneously,making them ideal for compact,high-stiffness applications like robotics,CNC rotary tables,and medical equipment.Available precision grades cover P5,P4 and P2;inner diameter ranges from 30mm to 1250mm while cross-section height varies between 8mm and 110mm.The rings and rollers are manufactured from GCr15 high-carbon chrome steel with surface hardness HRC 60-62 or corrosion-resistant SUS440C stainless steel,and nylon 66 serves as lightweight bearing cage material.Two sealing options are available:standard open type for clean environment and UU/U contact rubber seal to block dust and liquid splashing with industrial heavy-duty grease lubrication.
Packaging and filling equipments are mainstream automated production machinery widely used in food,beverage,daily chemicals,pharmaceuticals,chemical materials and other industries.Core components include rotary filling turntables,rotary packaging workstations,indexing rotating platforms and rotating conveying mechanisms.These devices are responsible for automatic filling,sealing,labeling and packaging of liquid,granular and powdery materials in industrial production lines.Most rotary spindles of such equipment are pre-assembled with gears and reducers before bearing installation,which creates major assembly obstacles for traditional integral bearings.During long-term operation,the rotary units have to withstand the dead weight of materials,frequent alternating impact loads and continuous cyclic rotation.Meanwhile,the working environment is often filled with liquid splashes,fine dust and humid air.Therefore,the supporting bearings are required to deliver outstanding load capacity,structural rigidity,sealing performance and operational stability.The performance of bearings directly determines the operating speed,product qualification rate and continuous production capacity of the entire packaging and filling line.
Multi-Directional Load Capacity:Unlike standard ball bearings,the crossed arrangement empowers the RB series to accommodate loads from all directions at once.
High Rigidity and Precision:The integration of a preload adjusts the bearing clearance,eliminating internal gaps and allowing for high rotational accuracy and minimal deformation under heavy loads.
Compact Space-Saving Profile:Because one crossed bearing replaces multiple conventional ball or roller bearings,they are exceptionally well-suited for tight,space-constrained assemblies.
Smooth Rotation:Spacer retainers separate the rollers,preventing them from skewing and eliminating friction between rolling elements for a stable,low-torque motion.
Industrial Robotics & Automation:Used in basic motion parts like rotary joints,waists,and wrists for smooth and precise motion control.
Precision Machine Tools:Utilized in the rotating tables of machining centers,rotary units of manipulators,and indexing heads to handle heavy,spinning components.
Medical Equipment:Deployed in sophisticated imaging components like MRI machines,CT scanners,and surgical robots to provide smooth,accurate,and vibration-free movement.
Semiconductor & IC Manufacturing:Provide micron-scale accuracy for wafer handling equipment,photolithography machines,and cleanroom pick-and-place systems.
Optical & Measuring Instruments:Essential for the tracking accuracy of astronomical telescopes,radar antennas,and Coordinate Measuring Machines (CMM).
Simplify On-site Assembly and Maintenance:The separable outer ring can be installed directly on the spindle with pre-mounted gears and reducers without dismantling existing components.It greatly shortens the equipment assembly cycle and reduces production and after-sales maintenance costs for machinery manufacturers.
Adapt to Complex Working Loads:A single RB bearing synchronously bears material weight,radial force and swing overturning moment.It simplifies the internal mechanical structure of rotary turntables and avoids structural loosening caused by long-term cyclic operation.
Ensure Accurate Filling and Packaging:P4/P2 high precision controls tiny rotational runout,enabling accurate positioning of filling nozzles and packaging stations.It effectively prevents material overflow,inaccurate filling and misaligned packaging,and improves the yield of finished products.
Resist Harsh Workshop Environment:UU double rubber seal effectively blocks liquid splashes,dust and humid air.The corrosion-resistant SUS440C stainless steel option is available for production scenarios with chemical and acidic materials,protecting internal bearing components from damage.
Suppress Vibration for Stable Operation:Ultra-high structural rigidity restricts vibration during high-speed rotation,keeping the equipment running smoothly.Stable operation avoids material splashing and excessive equipment wear during high-volume continuous production.
Extend Service Life and Reduce Downtime:Excellent fatigue resistance enables 24-hour uninterrupted operation of packaging and filling production lines.It cuts the frequency of bearing replacement and routine maintenance,and maximizes the overall production efficiency of enterprises.
