Durable Non-Geared Crossed Roller Slewing Bearings for Wind Turbines

Crossed roller gearless slewing bearings are generally composed of four components: an inner ring, an outer ring, rolling elements, and separators. As a type of slewing bearing, they can simultaneously bear axial loads and radial loads. Although there are multiple types of crossed roller slewing bearings, their core structures remain fundamentally consistent. A single-row crossed roller slewing bearing consists of two rings (inner and outer), featuring a compact design, lightweight construction, and high manufacturing precision. It is capable of handling axial loads, overturning moments, and large radial loads simultaneously. Depending on the application, a ring gear with either internal or external teeth can be integrated. Additionally, these bearings are characterized by easy installation and operation. Widely used in diverse machinery, crossed roller slewing bearings find applications in lifting, transportation, and construction equipment.
