Sankyo's DT/RT series features a low profile design cast iron housing with a ground pilot flange for mounting dial plates, hub less gears, or weldment fixtures. Above the indexing dial, a second dial mounting surface is stationary and hollow to allow air lines, wiring or bearings for a shaft to be routed through the tolerance bore. A globoidal cam rotates Sankyo made needle bearing type cam followers. Optimizing the cam follower diameter inherently maximizes torque transfer and extends the life hours due to fewer rotations with increased surface contact. Our DT series offers multiple index periods to run continuous mode or 'on demand' duty cycles with the indexing flange locking in position within 30 arc seconds during each dwell period. The output flange turret is mounted with top and bottom tapered bearings which supports large bending moments, maintain rigidity and reliability. These versatile units index in both directions or oscillate by reversing the motor using a VFD (variable frequency drive) controller.

The RT series is capable of performing non-patterned motions in forward or reverse direction with a continuous lead cam using programmable servo driven motors. Motor drive Accessories include inexpensive gearmotors, Sankyo's R series low backlash worm drive reducer that is compatible with servo motors or belt driven reducer on the larger units. Sizes 8, 11, 14, 18 & 25DT are offered with an optional output torque limiting clutch. Mounting between the index and the rotating dial, it features an adjustable torque range without disassembly and overload detection. Timing cam packages are available with inexpensive photo beam sensors or proximity switches for wash down (IP67/NEMA-6P) applications.
