CRBH Cross Roller Bearings are ultra-precision,high-rigidity bearings featuring cylindrical rollers arranged at right angles between the inner and outer rings.This single-unit design allows them to simultaneously handle complex loads in all directions-radial,axial,and moment.Core Basic Specifications Accuracy grades:P5,P4,P2 ultra-precision levels for micron-level positioning.Metric size range:Inner diameter 20–1250 mm,outer diameter 36–1500 mm,cross-section height 8–110 mm;miniature models like CRBH208A with only 8mm cross-section fit compact small indexing turrets of filling and packaging equipment Material options:Bearing rings and rollers adopt GCr15 high-carbon chromium steel (surface hardness HRC 60–62) for general food & packaging workshop environments;SUS440C stainless steel for corrosion-resistant,water-washable,food-grade production lines exposed to liquid splashes and cleaning agents.Cage materials include lightweight Nylon 66,high-strength brass,and customized composite materials.Sealing forms:Open type CRBH-A for dry dust-free packaging clean rooms;double-side contact rubber sealed CRBH-AUU for liquid splash,water cleaning and dusty filling production lines Lubrication modes:Food-grade long-life anti-emulsification grease lubrication for filling equipment ≤120°C;circulating oil lubrication for high-speed continuous indexing turntables up to 3000 rpm Delivery cycle:Standard stock models 7–15 days;custom food-grade anti-rust non-standard specifications require separate negotiation on production lead time
Rotary filling and multi-station packaging indexing turntables are core rotary indexing components of automatic food,medicine,cosmetic and daily chemical filling & packaging production lines.They carry multiple station fixtures to complete continuous cyclic processes including bottle feeding,liquid filling,sealing,cap screwing,labeling,boxing and discharging through intermittent rotary indexing motion.During long-time non-stop mass production,the turret bears uneven weight of bottles,cans and finished goods,as well as alternating overturning moment generated by repeated start-stop indexing.The working environment has frequent liquid splashes,residual raw material dust and regular high-pressure water washing for hygiene disinfection.Ordinary bearings are prone to rust,clearance loosening and indexing position deviation under such conditions,which will cause inaccurate filling volume,misaligned cap tightening and production line shutdown.Therefore,the core rotary bearing must have high load capacity,zero backlash positioning,waterproof sealing and food-grade anti-corrosion performance to meet continuous high-cycle packaging production.
Multi-Directional Load Capacity:Cylindrical rollers are arranged crosswise at 90° angles in a V-groove,allowing a single bearing to handle loads from all directions simultaneously.
Integrated,Non-Separable Rings:Because the inner and outer rings are solid and do not separate,the bearing's performance is unaffected by the surrounding mounting structure.
Smooth Rotation:They utilize separators between the rollers to prevent friction and ensure smooth,stable rotation,even at medium-to-high speeds.
High Precision & Rigidity:The line-contact design between rollers and raceways keeps elastic deformation incredibly small,resulting in superior stiffness and minimal backlash.
Industrial Robotics & Automation:They are the premier choice for articulating robot joints (bases,waists,and wrists) and speed reducers,where they provide the precise motion control and rigidity necessary for heavy or delicate tasks.
Machine Tools:Employed extensively in CNC rotary tables,grinding machines,and turning centers,where heavy spinning components meet high resistance,they minimize mounting errors and offer high rigidity during operations.
Medical & Imaging Equipment:Their smooth,vibration-free rotation and compact size make them ideal for positioning articulating arms in labs and ensuring the precise rotation of camera or imaging components in CT scanners and MRI machines.
Semiconductor Manufacturing:They deliver the micron-scale precision and repeatability required for pick-and-place systems and wafer handling equipment.
Rotary filling & multi-station packaging indexing turntables:Food-grade sealed SUS440C CRBH bearings act as core rotary supports for rotary liquid filling turrets,multi-station labeling indexing tables,automatic capping rotary platforms and pharmaceutical blister packaging rotating fixtures,delivering stable zero-backlash intermittent indexing rotation for continuous filling and packaging production lines.
Single bearing bears uneven cargo loads to prevent turret tilt:Filling and packaging turrets are loaded with bottles of different weights at each station,creating large eccentric overturning moment during indexing rotation.A single CRBH bearing replaces multiple sets of combined bearings to evenly disperse radial,axial and tilting loads,effectively restraining turret micro-deformation.It keeps bottle mouths aligned with filling nozzles and cap heads,avoiding liquid overflow and unqualified screw caps caused by platform inclination.
Zero-backlash preloaded structure ensures accurate station indexing:CRBH adopts factory integrated preload design with complete elimination of internal clearance.During high-frequency intermittent rotation,ultra-low rotation runout realizes repeatable micron-level station positioning accuracy,ensuring consistent filling volume and precise labeling position,drastically reducing product reject rate in automated packaging lines.
Stainless steel + double UU sealing adapts washdown food workshops SUS440 stainless steel:CRBH variants resist corrosion from food liquids,alcohol disinfectants and alkaline cleaning water; double-side rubber UU seals block liquid splashes,powder dust and cleaning water from entering the raceway.It avoids bearing rust and premature wear under daily equipment washing,greatly extending service life on hygiene-critical filling lines.
Food-grade low-friction lubrication meets sanitary production standards:Custom food-safe non-toxic,non-outgassing grease is matched for CRBH bearings,which will not contaminate food,pharmaceutical and cosmetic products even in case of tiny grease seepage.Low friction torque reduces servo motor load,lowering production line energy consumption during long 24-hour operation.
Ultra-thin integrated design optimizes packaging machine layout:CRBH thin-wall integral structure removes bulky multi-bearing stacking and auxiliary support frames,shrinking the overall height of indexing turrets.Compact rotary structure shortens the machine footprint,saving factory workshop space and facilitating overall equipment layout of multi-process packaging lines.
High anti-fatigue performance cuts production line downtime:GCr15 or stainless bearing rings with surface hardening treatment improve anti-fatigue performance by 30%,adapting millions of start-stop indexing cycles of packaging turrets.Less frequent bearing disassembly,cleaning and replacement reduces production line standby loss and factory maintenance labor costs.
Simplify filling machinery design and assembly flow:Different from RB split outer ring bearings requiring on-site preload adjustment,CRBH integrated inner and outer rings complete fixed preload at the factory stage.Packaging equipment manufacturers do not need to design complex clearance adjusting structures for turret housings,shortening R&D,assembly and precision calibration cycles of rotary filling and indexing equipment.
