Cross cylindrical roller slewing bearings are compact,high-rigidity bearings with cylindrical rollers arranged at 90-degree right angles to each other in a single alternating row between an inner and outer ring.
It is available in gearless,internal-geared or external-geared versions to satisfy diverse transmission needs.Typical outer diameter ranges from 300 mm up to 6000 mm,and custom dimensions are supported for special machinery requirements.The bearing rings adopt 42CrMo,50Mn or C45 alloy steel,while rolling rollers are made of high-wear-resistance GCr15 steel,achieving raceway hardness HRC 55-62 after quenching heat treatment.
90°Orthogonal Roller Arrangement:Cylindrical rollers alternate direction along a 90°V-groove raceway.This allows a single row of rollers to transmit loads in all directions simultaneously,effectively replacing two rows of standard bearings.
Simultaneous Multi-Load Capacity:Capable of handling severe axial loads,radial loads,and overturning (tilting) moments concurrently without requiring secondary support bearings.
Line Contact for High Rigidity:Because cylindrical rollers form a line of contact with the raceway (rather than point contact like ball bearings),elastic deformation under load is minimal,delivering exceptionally high structural and tilting stiffness.
Compact Cross-Section:Provides high dynamic and static load ratings relative to its boundary dimensions,saving substantial weight and space in heavy equipment turntables.
Integrated Drive Options:Frequently manufactured with gear teeth directly integrated into either the inner ring,the outer ring,or left ungeared.This streamlines the slewing drive mechanism design.
Split-Ring Design:Typically features a split inner or outer ring held together by mounting bolts to facilitate precision manufacturing,roller assembly,and factory clearance control.
Precision Machine Tools & Automation
Machine Tool Turrets & Indexing Tables:Applied in CNC rotary indexing tables,vertical boring mill turntables,and tool turret changers.
Industrial Robotics & Cobots:Integrated into the main waist and base articulation joints of heavy-load palletizing,welding,and material-handling industrial robots.
Automated Assembly Line Turntables:Used in high-precision indexing platforms and rotary transfers where zero-backlash and high tilting stiffness prevent table deflection under offset machining loads.
Construction Machinery & Material Handling
Medium-to-Large Mobile Cranes:Serves as the primary slewing ring connection between the crane superstructure and undercarriage in truck cranes,tower cranes,and crawler cranes.
Excavators & Demolition Equipment:Applied in compact or high-duty excavators and hydraulic rotators where line-contact support manages intense dynamic shock loads and tilting moments better than ball bearings.
Port & Marine Handling Gear:Used in deck crane bases,ship davits,and container handler slewing drives.
Radar,Optical & Aerospace Systems
Satellite Communications & Radar Bases:Fitted into the base turntables of mobile military radar antennas and satellite tracking dishes.
Astronomical Telescopes & Optics:Supports the main azimuth and elevation rotary stages in large optical or radio telescopes,requiring smooth rotational movement without stick-slip behavior.
Semiconductor & Medical Equipment
Medical Diagnostic Scanners:Used in CT scanner gantries and radiation therapy positioning tables where smooth rotation,high load capacity,and large hollow central bores are needed.
Wafer Handling & Cleanroom Automation:Applied in semiconductor inspection stages and flat-panel display handling equipment that require precise multi-axis positioning.
