FV Bearing is a leading supplier of precision bearings and bearings related products across a large spectrum of customers – preimarily OEMs and major distributors.
The era of Industry 3.0 and Industry 4.0 is the era of industrial automation and intelligence. Industrial robots and precision automated production lines are constantly replacing human labor. Using machine arms to replace humans in doing repetitive, precise, or long hours of heavy work. Cross roller bearings and harmonic reducer special bearings are the most widely used types of bearings in robots and automation equipment. Accuracy class: P4, USP, P2 Size range: 50-1200mm
The era of Industry 3.0 and Industry 4.0 is the era of industrial automation and intelligence. Industrial robots and precision automated production lines are constantly replacing human labor. Using machine arms to replace humans in doing repetitive, precise, or long hours of heavy work. Cross roller bearings and harmonic reducer special bearings are the most widely used types of bearings in robots and automation equipment.
With the crossed roller bearing, cylindrical rollers are arranged crosswise, with each rollerperpendicular to the adjacent roller, in a 90° V groove raceway, separated from each other by aspacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the crossed roller ring achieves highrigidity and the precision can reach up to P5,P4,USP and P2, despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots,swiveling tables of machining centers, precision rotary tables, medical equipment, measuring instruments and lC manufacturing machines. The spacer retainer ftting among cross-arrayed rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers, the cross roller ring does not cause displacement or locking of rollers and provides a stable rotation torque. Since the inner and outer rings are designed to be separable, the bearing clearance can be adjusted In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.
USAGE CHARACTERISTICS
The inner and outer rings, which are separable, are secured to the cross roller ring body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other. Thus, it is easy to handle the rings when installing the cross-roller ring. The spacer retainer keeps rollers in their proper position, there by preventing them from skewing. This eliminates friction between rollers, and therefore secures a stable rotation torque.the cross array of rollers allows a single cross-roller ring unit to receive loads in all directions, increasing the rigidity to three to four times greater than the conventional type.
