Rotary Table Bearings

Axial/radial bearings YRT, RTC and YRT Speed and axial angular contact ball bearings ZKLDF are ready-to-fit high precision bearings for high precision applications with combined loads, such as rotary tables, face plates, milling heads and reversible clamps.

Product Description

     

Bearing supports for rotary tables in production machinery are one of INA’s most high developed areas of competence. Their range of low-maintenance axial/radial bearings and axial angular contact ball bearings as well as axial needle roller and cage assemblies and axial bearing washers is the widest and most highly developed worldwide for production machinery.

For rotary tables, face plates, reversible clamps, milling heads or measuring and inspection equipment – NEWORLD engineers can provide you with the best technical and economic solution for all requirements as per to INA.

INA YRT Series

For standard applications, the proven INA series YRT ranks number 1 worldwide. Its acknowledged reliability, accuracy, cost-efficiency and ongoing development were and remain the guarantors of success. The dimensioning of all bearings for rotary tables has been defined so that they are interchangeable with each other. This gives increased flexibility in the design of a machine tool. Where compact designs with a restricted section height are involved, axial needle roller and cage assemblies of series AXK are available.

 

INA YRTS Series

The optimized axial/radial cylindrical roller bearing of series YRTS is without equal in the market for applications requiring very high limiting speeds and maximum rigidity. It also exhibits extremely low and consistent frictional torque characteristics as well as increased levels of tilting rigidity. The reductions in friction give consistently low bearing temperatures, which exerts a positive influence on the accuracy of the entire machine subassembly. As a result, YRTS bearings for highly dynamic accelerations are an ideal partner in direct drive rotary tables, in order to make effective use of the potential performance of direct drives. These bearings can optionally be equipped with an angular measuring system incorporating pitch-coded reference marks (YRTM, YRTSM).

 

INA YRTSMA Series

With its YRTSMA, Schaeffler is the first manufacturer in the world to develop a high precision rotary table bearing that has a directly integrated absolute value angular measuring system. This gives a considerable reduction in the mounting work required. In addition, the free space in the center of the axis opens up completely new design options.

The electronic measuring system and IDAM direct drives complement each other extremely well. Since the system components are connected to the adjacent construction by a method that is resistant to vibrations, the influence of vibrations due to machining is substantially prevented.
