The advantages and disadvantages of crossed roller bearing and rotary table bearings

Rotary Table Bearing and cross roller bearings on the function and structure are similar, such as high rigidity, high precision, stable rotation torque, long life and other aspects of performance. In industrial robot joints, nc rotary table, dividing disc, vertical grinding machine, direct drive motor, precision medical equipment and other high-precision processing equipment more and more to abandon the traditional design, the better performance of high precision cross roller bearings.

Rotary Table Bearing domestic popular also called turntable bearing or rotary bearing, is a German company developed a kind of similar to the three row roller rotary bearing structure of the bearing type, relative to the three row roller combination of rotary bearing structure, the advantages of small size, precision grade, high rigidity, high bearing load and resistance to damage, etc. It is mainly used in high-precision CNC turret, nc dial, vertical machining center, vertical grinding machine, military radar and precision medical equipment.

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.

How to select high precision cross roller bearing and YRT turntable bearing?

YRT turntable bearing is a rotary mechanism of outer ring and inner ring support. It is mainly divided into three series: YRT, YRTS and YRTM.How to select high precision cross roller bearing and YRT turntable bearing?

The space of the cross roller bearing can be constrained.In most cases, the axis (or cross roller bearing inner ring) is based on mechanical or other delineation constraints.Therefore, the selection of cross roller bearing type and scale is based on the internal diameter of cross roller bearing.Therefore, the first scale of the standard cross roller bearing is based on the international standard.
Specification method of heavy and complicated of the scale of the cross roller bearing, the best choose on machinery and equipment, standard cross roller bearings,cross roller bearing load on the cross on the roller bearing load, the nature, intrusive, direction is changeable.In general, the extra basic load is shown on the scale.However, axial load and radial load are also important factors for selecting suitable cross roller bearings.When the ball and needle bearing are at the same time, the cross roller bearings generally have higher load capacity and accept larger oscillations and impact loads.
