Product Description

 

Cross roller slewing bearings are high-precision, high-rigidity rotational support components widely used in equipment requiring combined load capacity (axial force, radial force, tilting moment) and precise rotation.

                                                                                                                                                                                                                     

Key Features
High Rigidity & Precision: Utilizes cross-arranged cylindrical rollers (90° orthogonal distribution) with line contact between rollers and raceways, providing enhanced load capacity and micron-level rotational accuracy.
Compact Design: A single bearing replaces traditional "bearing + slewing ring" combinations, saving space.
Low Friction: Features minimal rolling friction coefficient and low starting torque, making it ideal for precision motion control.
Multi-Directional Load Capacity: Simultaneously handles axial, radial forces, and tilting moments, suitable for complex working conditions.
 

Selection Considerations:
Load Analysis: It is necessary to calculate the combined loads and moments under actual working conditions to avoid overloading.
Installation Method: Horizontal or vertical installation affects bearing clearance and service life.
Environmental Adaptability: Corrosive environments require stainless steel materials or special coatings.

Slewing bearing Features: 
Slewing bearing has more features: compact structure, reliable guide, simple installation, and easily maintenance.
4.Slewing bearing application
Slewing bearings can be widely used in lifting transport machine, mining machine, construction machinery, port hoisting machinery, port oil transfer equipment, onshore and offshore crane, excavator, concrete machine, paper machine, plastic and rubber machine, weave machine, steel plant, electronic power plant, wind power generator, other construction and industry machines or equipments and other large rotary device.
 

Rollers are arranged in a cross pattern to form an "X" layout, decomposing the load into axial and radial components, simultaneously resisting multi-directional forces.
Line contact load-bearing: The contact area between rollers and raceways is large, increasing load-bearing capacity by 3-5 times compared to the point contact of ball bearings.
Adjustable preload: Preload can be achieved by adjusting the spacing between inner and outer rings or using shims, eliminating clearance and improving rigidity (suitable for precision machine tools).
