High precision cross roller bearings ultra-precision rolling bearings with cylindrical rollers arranged vertically and crosswise at 90° in V-shaped raceways,separated by isolation blocks or precision cages. Differing from standard bearings,they adopt P2/P4/P5 micron-level precision grinding,and can bear radial,axial and overturning moment loads simultaneously with a single set. They feature compact structure,high rigidity and ultra-smooth rotation,serving as core components for precision transmission in high-end equipment.
Ultra-high Precision:Runout is controlled at micron level,meeting strict positioning requirements of precision equipment with P2/P4/P5 precision grades.
High Rigidity & Load Capacity:Cross-arranged rollers form line contact with raceways,delivering strong resistance to deformation and bearing complex combined loads stably.Compact & Lightweight:Save over 50% installation space compared with traditional bearing combinations,adapting to miniaturized design of precision machinery.
Low Friction & Stable Rotation:Optimized roller profile and super-finished raceways reduce friction torque,ensuring smooth and low-noise operation.
Flexible Structure:Available in integral or separable designs (inner/outer ring split),with RU series equipped with mounting holes for easy installation.Wide Adaptability:Made of high-carbon chromium steel or stainless steel,suitable for clean,precision or weak corrosive working conditions.
They are widely used in high-precision fields:
Industrial Robots:Joints of six-axis and collaborative robots to ensure precise and flexible movement.
Machine Tools:Fourth/fifth-axis rotary tables and spindles to maintain machining accuracy.
Medical Equipment:CT gantries,surgical robot joints and precision diagnostic instruments.
Semiconductor Equipment:Wafer handling robots and lithography machine positioning platforms.
Aerospace:Radar antenna bases and satellite communication steering mechanisms.
Precision Instruments:Coordinate measuring machines and optical equipment rotating parts.
Precision Grade:P2/P4 ultra-precision models are 40%-80% more expensive than P5 standard precision ones.Size & Series:Larger diameter (over 500mm) and special thin-section models cost more due to complex processing.Material:Stainless steel or ceramic hybrid materials increase cost by 30%-60% compared with standard chrome steel.Structure:Separable and mounting-hole integrated designs are pricier than integral types.Order Quantity:Bulk orders (≥100 pieces) enjoy 15%-25% discounts; small-batch or urgent orders raise unit price by 20%-35%.
Confirm Working Conditions:Match load type,speed,temperature and environment (clean/corrosive).Select Precision Grade:P2/P4 for ultra-precision equipment,P5 for general precision machinery.Verify Size & Load:Ensure inner/outer diameter,width and load rating meet actual needs with 1.2-1.5 times safety factor.Choose Structure:Separable designs for difficult installation scenarios,integral types for higher rigidity.Material & Lubrication:Standard chrome steel for normal use,stainless steel for corrosion resistance; match lubricant to speed and temperature.
