3D models of off-the-shelf telescopic slides
Telescopic ball bearing slide designer and manufacturer, Accuride International, has produced optimised 3D models of its 'off-the-shelf' products which can be downloaded via its website.
Large area air bearings provide sufficient payload stiffness and maximises performance in respect to wobble and run-out.
Radially distributed RotoLinear motoring modules provide high positioning stiffness during rotary indexing and when installed on moving XY tables.
These rotary tables provide unlimited rotation and are capable of precise positioning and velocity controls.
RotoRings rotary tables can be mounted in any orientation and have "large open centre design".
When used in processing 12" semiconductor wafers, every area of the wafer can be accessed.
In general automation applications large open centre offers the opportunity to access parts from inside and outside of the table simultaneously.
This feature allows robotic devices, pick and place and ancillary tooling to be mounted inside the table, saving floor space and reducing parts handling with increased productivity.
