Product Description
Cross tapered roller bearings produced by Luoyang East Axis have two sets of raceways and rollers, which are combined at right angles to each other, and the rollers are staggered and opposite. The cross-sectional height of the bearing is similar to that of a single-row bearing, thus saving space and bearing seat materials. The large cone angle and cone geometry design make the overall effective span of the shaft several times the width of the bearing itself. Cross tapered roller can bear high overturning moment, and is suitable for machine tools, including vertical boring machine and grinder workbench, precision indexing workbench of machine tools, large gear hobbing machine, turret, industrial robot, etc.
Lydz bearing features:
1. high precision: the precision can reach p4 and p2 levels;
2. High rigidity: This series of bearings are loaded with preload;
3. High load: It can bear axial load, radial load and overturning load.
4. Small size: The bearing is small, which can save space for the main engine.

Lydz industrial robot bearing features: 1. It can bear comprehensive loads in axial, radial and overturning directions; 2. Thin-walled bearings; 3. High rotary positioning accuracy. Any bearing that can meet this design requirement can be used in industrial robot arms, swivel joints, chassis and other parts. Cross roller bearing is a typical industrial robot bearing, which can be used in robot arm and rotary joint.
Lydz cross roller bearing, which is characterized by one raceway and two rows of rollers arranged in cross. Compared with the traditional combination of thrust bearing and radial centering bearing, the cross roller bearing has compact structure and small volume, and simplifies the design of the worktable, thus reducing the cost of the turntable. In addition, due to the optimized pre-tightening force, this kind of bearing has high rigidity, so the rigidity and precision of the turntable are also guaranteed. Thanks to the design of two rows of crossed rollers, the effective span of the bearing can be significantly increased, so this kind of bearing has high overturning moment resistance.
