Cross-roller slewing bearings are high-precision slewing bearings that utilize cylindrical rollers arranged crosswise on 90-degree raceways. They can simultaneously withstand axial, radial, and overturning moments, offering superior load-bearing rigidity and rotational accuracy.
Crossed roller slewing bearings are a high-precision, high-rigidity type of single-row slewing bearing. Their key feature is that the internal row of rollers is arranged at a 90° angle, with the rollers making line contact with the inner and outer raceways. This design allows them to simultaneously withstand axial forces, radial forces, and overturning moments, exhibiting outstanding performance in terms of rigidity and rotational accuracy. They are a core component of precision rotating equipment.They are suitable for medical CT scanners, automated robots, radar satellites, and small to medium-sized excavators and cranes.
Cross-roller slewing bearing features
Adjacent rollers are arranged at a 90-degree angle to each other axially.The cross-roller arrangement provides a compact and rigid structure.
The rollers are arranged in a 1:1 cross pattern to withstand large radial forces, axial forces, and overturning moments.
It consists of two seat rings,high rotational accuracy and low friction.
LTZC crossed roller slewing bearings feature a closely spaced crossed roller structure, capable of simultaneously withstanding radial loads, axial loads, and tilting moments.Crossed roller slewing bearings belongs to the category of high-load slewing bearings and high-speed slewing ring.It is most commonly found in heavy machinery such as cranes, excavators, and stacker-reclaimers.
Each LTZC bearing undergoes precision grinding and advanced machining and testing processes to ensure superior positioning accuracy, the rollers in a crossed roller slewing ring are arranged in a 1:1 crossed pattern, which ensures stable and precise rotation of the bearing.Making it suitable for automation equipment, medical devices, military, and aerospace applications.
LTZC crossed roller slewing bearings undergo HRC 55-62 heat treatment, resulting in higher rigidity and load capacity.
