The dimension design characteristics of this series of indexing drives are similar to flange type functions. They can bear super-large axial load and vertical radial pressure in driving operation. There is a convex fixed disk surface and large aperture hollow shaft at the output end. They can be equipped with dynamic and static automatic peripheral settings,It takes power supply, oil and gas pipelines in the Hollow place. This series of indexing drive are widely used in the all kinds of mechanisms and industrial machinery of heavy load and direct junction automation equipment for synchronous automation intermittent drive.
