Its primary innovation is a large, fixed hollow central axis integrated into the output flange, which allows cables, air lines, or other media to pass directly through the device. This “hollow flange” design eliminates external cable management systems, simplifies machine architecture, and saves space. Mechanically, it employs a globoidal cam—a precision-machined input shaft—that drives a turret fitted with roller bearings. A Hollow Cam Indexing Drive is a specialized mechanical device used in automation and machinery to achieve precise rotational positioning and indexing.

Yes, with proper lubrication it supports long-term continuous operation, with low heat generation and high reliability.What is the difference from ordinary rotary indexing tables? It uses a cam roller drive for higher speed and rigidity, while the hollow design offers better integration than solid-shaft models.Can it bear heavy radial and axial loads? Yes, its built-in heavy-duty bearings provide strong load capacity, suitable for workpiece processing and multi-station tooling loading.Can it match with servo or variable speed systems? Yes, it can be equipped with a servo motor to adjust speed and indexing time, adapting to flexible production line requirements.How do I seal the hollow bore when passing cables or air lines? Use a static seal plate at one end and a rotating seal gland at the other if the bore rotates. For cables that must rotate with the output, install a hollow rotary union with lip seals. About stationary pass-through (cables fixed while output rotates), use a fixed tube inside the bore with O-rings at both ends. For dust or washdown environments, specify double-lip seals with air purge ports. Typical IP rating for hollow cam drives: IP65 (dust and low-pressure jets) with standard seals, IP67 with optional Viton seals. Never leave the bore open—debris will damage internal bearings.You are welcome to watch more projects or visit our website to check other series or load down e-catalogues for further technical data.
