Precision Rotary Table Bearing

Product description product variants product description.
Precision rotary table bearing. Built for the most demanding applications every table provides ultra smooth motion sub micron accuracy and absolute repeatability. Abtech s line of precision mechanical rotary tables address the motion needs for a full range of part sizes and weights. Precision rotary tables may be externally driven via belts or worm and wheel or alternatively can be fitted with an integral drive motor. They can support radial loads axial loads from both sides and tilting moments without clearance and are.
Abtech s precision air bearing rotary tables address the metrology needs for different weights and part size. They feature an integrated design that includes an l shaped inner ring shaft washer outer ring two thrust roller cage assemblies and a radial full complement row. High precision angular contact bearings are incorporated into stages that are designed and manufactured in house to extremely tight geometric tolerances. Miniature positioning stages compact positioning stages are crucial for the miniaturization process in cutting edge research and industrial applications for test measurement optical.
Mechanical bearing rotary tables. The abrt series precision rotary tables from jena tec utilise robust high precision roller axial bearings with an air bearing in the horizontal axis for smooth precise rotary motion. All tables feature the low axial motion errors inherent of air bearings. Super precision axial radial cylindrical roller bearings are commonly used to support rotary tables indexing heads and multi spindle heads on machining centres.
We can help you match the ideal product to your specific applications by first understanding what your needs are and then explaining the differences advantages and disadvantages of air bearing oil bearing and. Skf manufactures super precision axial radial cylindrical roller bearings for shaft diameters from 80 to 850 mm. Air bearing stages linear rotary and spherical replace mechanical contact by a thin air film avoiding wear friction vibration and hysteresis effects. Rotary air bearing tables accuracies to 2 0 µ abtech s standard line of high precision rotary air bearing tables at series and heavy duty rotary tables hdrt series are ideal for low speed tir measurements optical inspection precision assembly or light machining and grinding where radial and axial accuracies down to 2 0 µ are required.
The air bearing principle offers a compact overall height of only 100mm with a cost effective bearing solution and high geometric accuracy. We have an extensive line of rotary air bearing oil hydrostatic and precision mechanical bearing tables for low speed applications. Axial radial bearings and axial angular contact ball bearings are ready to fit precision bearings for high precision applications with combined loads. The use of dc brushless torque motors with high resolution encoders can achieve angular position resolutions better than 0 1 arcsecs.
