Overview
The TCY-80 is a single-stage precision cycloidal reducer. An eccentric input drives a ground cycloid disc around a ring of pins; many lobes share the load at once, which gives high shock capacity and low wear. The flange output rides on a cross-roller bearing, so a table or arm can mount directly on it.
Use it for rotary index tables, palletising robot joints, feeders and any axis that reverses often under load.

Send your motor detailsQuestions about the TCY-80
Can the TCY-80 carry a rotary table directly?
Yes. The cross-roller output bearing takes up to 500 N·m tilting moment and 4,000 N axial load. Check your table's off-centre load against these values.
