What are the classifications of YRT rotary table bearings?

The YRT turret bearing consists of a set of thrust/central races, a thrust/central shaft collar, a thrust washer, two needle roller cage assemblies and a set of centripetal cylindrical rollers. The seat ring and collar have uniform mounting screw holes. This type of bearing has high axial and high radial load carrying capacity, high tilt stiffness and high precision. Suitable for rotary tables, as well as bearing devices for measurement and experimentation. This type of bearing has higher requirements for the matching equipment parts. The tightening torque of the mounting screws needs to be controlled during installation.
Scope of application: It is widely used in precision rotary table vertical grinding machines, indexing heads, gear hobbing machines, gear milling machine workpiece axes and other precision devices.
YRT standard series
The thrust-central combination structure can withstand bidirectional axial loads, radial loads and overturning moments. The bearing is uniformly provided with mounting holes, which can be directly fixed to the bearing by bolts; the bearing has been preloaded at the factory, and the installation does not need to adjust the clearance; the YRT rotary table bearing series is suitable for low speed, short running cycle, rigidity and precision. High requirements, such as rotary table, indexing head, etc.
YRTS high speed rotary table bearing series
The external structure is the same as the YRT series, but the internal structure is different from the YRT series. This determines that the YRTS rotary table bearing series has higher limit speed than the YRT series. The friction torque is lower and uniform than the YRT rotary table bearing series. Therefore, it requires relatively low friction. However, for relatively high speed applications, this series can be used, such as bearings for shafts driven by direct drive motors.
ZKLDF thrust angle contact ball series
The ZKLDF thrust angular contact ball series can also withstand combined loads, but with extremely high speed and extremely low friction torque, while ensuring high rotational accuracy. Ideal for applications with such requirements, such as high-speed rotary tables, milling, grinding, and precision measurement and measurement equipment.
YRTM double direction thrust cylindrical roller combined bearing with angle measuring system
This series of bearings is based on YTR rotary table bearings. An angle measuring system is installed on the YRT rotary table bearings to accurately measure and adjust the angle of bearing rotation to ensure high-precision operation of the machine.
The measuring system consists of a sensor component and a measuring rule. Using purely inductive measurement principle, the signal is extremely accurate and the measurement accuracy is high. At the same time, due to the use of high precautions, the measuring system is not subject to external interference during operation, such as dust and smoke, mild oil and scratches, magnetic fields, etc. It is reliable, does not require excessive maintenance, and has a wide range of applications. . It can be applied to high-precision rotary tables and rotating shafts, indexing heads, military radars, aerospace, aerospace and measurement and testing areas requiring high angular rotation accuracy.
