Ring Indexing Tables are suited for use with Gemotec system.
November 4, 2009 -
Pneumatically driven RST series compact ring indexing tables include RST 18 with 70 x 70 mm footprint, 1.2 Nm torque, and maximum axial force on cycle ring of 1,950 N. Model RST 24, measuring 100 x 100 mm, offers 4 Nm torque and axial force of 3,400 N on cycle ring. Both can cycle left, right, or alternate without modifications. They allow working process to be stopped, reversed few steps, and processing step in question to be repeated should error occur.

Schunk Introduces Compact Ring Indexing Table
Schunk has expanded its product range and now offers a compact ring indexing table for assembly applications within the Gemotec system.
The RST series is pneumatically driven and is available in two different sizes with the RST 18 and RST 24. Their key differences are the footprint (70x70 mm / 100x100 mm), torque (1.2 Nm / 4 Nm) and in the maximum axial force on the cycle ring (1950 N / 3400 N).
The ring indexing tables can cycle either to the left or the right or alternate, without requiring any modifications. Switching is performed by the pneumatic actuation alone, and the cycle types can be changed in any order and any number of times. Thus, the RST series allows the working process to be stopped, to return a few steps and repeat the processing step in question if errors occur - a unique feature not offered by any other manufacturer.
The angle adjustment can be set simply to 4, 6, 8 or 12 steps. Hydraulic shock absorbers are used as end position dampers in both directions. The repeat accuracy of the angle of rotation is less than 0.03°, the axial and radial run-out of the cycle ring is better than 0.02 mm.
As only the cycle ring rotates in the RST series, its special feature is an unusually large fixed central section. This makes it easier to add additional components and assemblies, and features a large feed-through bore. For example, it allows additional assemblies to be supplied with compressed air without the air hoses having to follow any rotating movements of the ring indexing table.
