Production Of SXU Crossed Roller Bearings

What are SXU Crossed Roller Bearings?

SXU (or XSU) crossed roller bearings are high-precision,low-profile bearings featuring cylindrical rollers arranged in a 90-degree V-groove pattern.Their unique "X" configuration allows a single compact bearing to handle radial,axial,and moment loads simultaneously.

Newbeetrans SXU series covers a complete size range from small miniature specifications to large-diameter models.The cross-section maintains an ultra-slim thickness,matching space-limited equipment layouts.Precision grades include P4 and P5 for selection,with open type,single seal (U) and double seal (UU) versions available.Standard material is quenched GCr15 bearing steel; SUS440 stainless steel customized versions are supplied for cleanroom,vacuum and corrosion-resistant working environments.

The features of SXU Crossed Roller Bearings

Integrated Ring Design:Both the inner ring and outer ring feature solid,single-piece construction,eliminating assembly errors and providing maximum structural stiffness.

Direct-Mount Installation:Outfitted with pre-drilled mounting holes directly on both inner and outer rings.This allows direct bolting to equipment without requiring specialized housing units or retaining flanges.

Multi-Directional Load Support:The $90^\circ$ cross-arranged rollers enable a single bearing to simultaneously handle radial loads,double-direction axial loads,and tilting moment loads.

High Rotational Precision:Optimized for minimal radial and axial runout,delivering micro-meter accuracy for both inner-ring and outer-ring rotation.

Compact,Space-Saving Profile:Offers a high load capacity relative to its ultra-thin cross-sectional area,significantly reducing overall equipment weight and footprint.

The applications of SXU Crossed Roller Bearings

Industrial Robotics & Automation

Robotic Articulating Joints:Used in robot wrists,elbows,and waists where multi-directional load capacity and compact joints are required.

Harmonic & RV Reducer Output Support:Mounted at the output of speed reducers to bear severe radial forces and tilting moments directly.

Machine Tools & CNC Equipment

Precision Indexing & Rotary Tables:Supports multi-axis CNC rotary tables and workholding fixtures requiring minimal runout and zero backlash.

Milling Heads & Tool Turrets:Handles machining vibration and cutting forces during multi-angle milling and turning operations.

Semiconductor & Electronics Manufacturing

Wafer Handling Robots & Alignment Stages:Delivers sub-micron positioning accuracy in vacuum or cleanroom environments.

Pick-and-Place Systems:Supports rapid acceleration and deceleration cycles in high-speed electronic assembly lines.

Medical & Healthcare Devices

Surgical Robots & Articulating Arms:Provides smooth,precise rotational movement for robotic surgical instruments.

Laboratory & Medical Imaging Equipment:Used in medical CT positioning stages,blood centrifuges,and precision patient support tables.

Metrology & Optical Systems

Coordinate Measuring Machines (CMM):Powers precision rotational indexing stages for measuring complex component geometries.

Radar & Surveillance Gimbals:Drives optical tracking cameras,laser targeting platforms,and antenna azimuth/elevation mounts.
