Hollow Rotary Platform Bearing ZK60 ZK85 ZK130 ZK200, Is a special type bearing with split inner ring and outer ring rotation. The divided inner ring or outer ring is fixed with the cross roller collar after the roller and the spacer are installed to prevent separation, so the operation is simple when installing the cross roller collar. because the inner or outer ring of the cross roller bearing has a two-part structure, the bearing gap can be adjusted, and even if a preload is applied, a high-precision rotary motion can be obtained. Moreover, due to its special structure, it can be applied to the joints and rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical equipments, measuring instruments, IC manufacturing machines, etc.
1. Hollow Rotary Platform Bearing Structure
The turntable of the hollow rotating platform is supported by a set of crossed roller bearings, the rollers in the bearings are staggered at 90 degrees, the linear bridging between the rollers and the raceway is more than 70%, which makes the crossed roller bearings have a strong bearing capacity, and the negative clearance between the rollers and the raceway is designed and manufactured, which completely eliminates the clearance generated when the radial, axial, tilting and other forces act.
High rotational positioning accuracy (up to within 0.002mm), accurate positioning without gaps; rigidity is more than 10 times that of traditional bearings and long life.
2. Hollow Rotary Platform Bearing Features
In the work of flexible bearing, the inner ring is installed on the elliptical cam, the outer ring is installed on the flexible wheel, and the elastic deformation occurs with the rotation of the cam, which not only bears the cyclic stress load, but also bears the alternating stress load.
3. Hollow Rotary Platform Bearing pplications
The crossed cylindrical roller bearings for hollow rotary table developed and produced by our company are designed and manufactured for positioning table, positioning hole and mounting hole, which facilitate the assembly and external chain use of host manufacturers and meet the needs of customers.
It is applied to hollow rotary table, DD motor motor DD MOTOR, cam divider, CNC indexing device, robot joint, fourth machining axis of machine tool, radar and other applications that require high precision, high rigidity and long life.
