Application of high-precision YRT rotary table bearings in fully automatic folding line machines.

In past years, high-precision YRT turntable bearings have been widely used in various automation equipment. Due to their high-precision and high rigidity characteristics, they can satisfy with the needs of precision machinery manufacturing. Taking the fully automatic folding line machine with high market demand as example, the YRT turntable bearings are introduced.

Automatic line bending machine, also known as linear bending machine, is a commonly used equipment in spring machinery, mainly used for bending various types of wires. Due to the increasing demand from customers, the accuracy and quality requirements for wire forming are becoming higher and higher, and the bending performance requirements for linear bending machines are also increasing. During the wire bending process, the working axis of the machine tool has to bear repeated overturning and rotating loads. Ordinary bearings cannot meet the requirements of bearing multiple loads and ensuring accuracy. Choosing YRT turntable bearings can solve such problems, The structure of the YRT rotary table bearing with three rows of cylindrical roller bearings not only ensures the large axial and radial loads on the working shaft of the linear machine, but also has excellent bearing capacity for torsional loads during the operation of the linear machine. It can ensure a rotational runout of less than 5 microns and ensure the positioning accuracy of the working shaft, thereby ensuring stable quality of the processed wire.

The YRT turntable bearing consists of a thrust/radial shaft ring, a thrust washer, two needle roller cage components, and a set of radial cylindrical rollers. The seat ring and shaft ring have evenly distributed installation screw holes. This type of bearing has high axial and radial load-bearing capacity. High tilt stiffness and extremely high precision. Suitable for rotary workbenches, chucks and milling heads, as well as bearing configurations in measurement and experimentation. This type of bearing also has high requirements for the matching equipment parts. During installation, it is necessary to control the tightening torque of the installation screws.

Application:

Widely used in precision rotary table vertical grinders, indexing heads, hobbing machines, milling machines, workpiece shafts and other precision devices.

YRT Standard Series:

A thrust centripetal combination structure that can simultaneously withstand bidirectional axial loads, radial loads, and overturning moments. There are mounting holes evenly distributed on the bearings, which can be directly fixed to the bearings using bolts.

The bearings are preloaded before leaving the factory, and there is no need to adjust the clearance during installation. 

The YRT turntable bearing series is suitable for applications with low rotational speed, short operating cycle, and high requirements for rigidity and accuracy, such as rotary workbenches and indexing heads.
