FRB Introduction of YRT series high precision rotary table bearing

As an important part of machine tool, rotary table bearings has always been the focus of machine tool design.As a key part of the workpiece, the rotary table bearing precision、rigidity and composite bearing capacity directly influence the machine tool processing performance.The choice of bearing plays a direct and decisive role.Traditional solution of the turntable bearings generally use two or more than two sets of radial and thrust bearings, the purpose is to make the turntable can also carry axial load, radial load and tilting moment, although this solution is mature, but there are also such as turntable structure design of complex, shortcomings and so on bearing inconvenient installation and maintenance.



YRT series high precision rotary table bearing, breaking through the traditional bearing selection and layout.A set of bearings can meet the requirements of the turntable to bear the combined load, greatly simplifying the structure of the turntable and reducing the design, installation and maintenance costs.The combination of a set of radial rollers and axial two row thrust rollers keeps the structure compact and saves space for the overall structure design of the turntable.Mounting holes are arranged on the bearing to make installation extremely convenient.High rigidity and high rotary precision can be achieved without adjusting the clearance.The inner ring and outer ring of the bearing are provided with oil injection holes to facilitate regular oil injection maintenance.The maximum rotary precision of YRT rotary bearing can be 1.5μm, which is much higher than that of ordinary bearings.

Thanks to FRB Bearings rich product line, in addition to standard YRT series is suitable for low speed applications, short cycle for more diverse applications, we also have the corresponding products and solutions.YRTS high speed turntable bearing series can be used for low friction moment and relative height occasions, suitable for straight drive motor turntable and double pendulum milling etc.ZKLDF thrust angular contact ball series has a very high speed, low friction torque, and also can bear joint load, high-speed rotary table is suitable for milling machining center, vertical grinding machine, such as measurement and control field.YRTM integrated series of turntable bearing Angle measuring system, through the integrated modular design to realize the accuracy of the angular measuring system from the Angle of rotation Angle and precise control integration, simplify the structure, very suitable for application in machining center CNC rotary table and indexing table, etc.
