DE cam indexing systems use a dual-eccentric (DE) groove cam to convert continuous rotary input into precise intermittent output motion. The cam profile drives roller-equipped input turrets, locking the output table at exact angular positions during dwell. Indexing angles range from 30° to 360° in standard configurations. Roller followers enter and exit the conjugate cam groove with zero backlash, maintaining positional repeatability within ±5 arc-seconds.
DE Cam Indexing Systems are specialized mechanical components used to enhance precision and efficiency in automated processes. These systems are primarily used for applications requiring the starting and stopping of a device at precise intervals and locations.

Industrial applications of DE Flange & Shaft Output Cam Indexing Systems
Food & Beverage: Aluminium can end seaming — 16-station rotary seamer
A DE flange output cam indexing system drives a 16-station aluminium can end seaming turret at 550 indexes per minute — the highest cycle rate in the can line. The turret carries seaming chucks at 185 mm flange radius; total output inertia is 6.8 kg·m². At 550 CPM, the DE conjugate groove transitions the turret through 22.5° index steps with a 195°/165° dwell-to-index ratio, maintaining ±5 arc-second repeatability that positions each can end within ±0.07 mm of the seaming roll centerline. The flange output mounts directly to the turret base plate through a 200 mm pilot register, providing the full flange face contact area needed to resist the 380 N·m seaming reaction torque without fretting at the joint. H1-rated oil fills the cam housing to meet food-zone lubrication standards under FSMA 21 CFR Part 117.
Pharmaceutical: Tablet blister sealing — 10-station forming and lidding indexer
A sealed DE shaft output cam indexing system steps a 10-station PVC/aluminium blister forming and heat-seal dial at 420 indexes per minute inside a pharmaceutical Grade C cleanroom. The dial carries thermoforming dies and lidding pressure pads at 130 mm radius; total output inertia is 1.9 kg·m². The DE unit runs at 420 CPM with a 216°/144° dwell-to-index ratio, holding each die station stationary for 0.857 seconds — sufficient for the 180°C heat-seal bar to form a hermetic foil bond without blister deformation from table motion. Output shaft repeatability of ±5 arc-seconds positions each blister pocket within ±0.04 mm of the lidding die centerline, meeting the pocket registration tolerance for serialisation camera reads at station 9. FDA 21 CFR Part 211 compliance requires the sealed grease variant with USP Class VI lubricant, zero oil mist emission, and a stainless output shaft with EP electropolish finish.
420 CPM exceeds the DS unit limit. The DE shaft output feeds a hollow rotary union supplying conditioned air to the thermoforming die cavity for controlled PVC draw temperature — identical integration logic to the HDD case. A flange output would block the shaft end, forcing an external air manifold that adds 90 mm to the machine width and creates a dead-leg contamination risk in the cleanroom airflow path.
FAQs about Cam Indexing Drive
- How Does a DE cam differ from a barrel cam indexer?
A barrel cam uses a cylindrical body with a helical groove to move an output turret. A DE cam uses a flat or disc-shaped eccentric groove. DE cams deliver shorter dwell transitions at equivalent speed, produce lower dynamic loading, and fit more compactly into flat-form machine layouts.
- Does a DE cam system need a brake to hold dwell position?
No. The conjugate groove geometry locks the output rollers mechanically during dwell. The cam profile holds the output table rigid without any external brake or clutch. This self-locking characteristic removes brake wear, simplifies wiring, and eliminates dwell drift under load.
- Can a DE cam indexer handle axial and radial laods simultaneously?
Yes. The output flange bears axial thrust and radial cutting forces through preloaded cross-roller or tapered-roller bearings integrated into the cam housing. Always check the combined load rating in the manufacturer’s load chart, as simultaneous axial and radial loading reduces maximum permissible values for each axis independently.
- How do roller follower wear,and when should they be replaced?
Needle or cylindrical roller bearings inside the cam followers develop spalling or flat spots after extended overload or contamination. Inspect followers every 5,000–10,000 operating hours. Replace followers when radial play exceeds 0.02 mm or when positional repeatability degrades beyond the system specification. Always replace all followers in a set, not individually.
- What cam profile law Do DE cam indexers use?
Most DE cam indexers use modified sinusoidal or modified trapezoidal motion laws. These profiles minimize peak acceleration and jerk at the transition between dwell and index. The modified trapezoidal law offers lower peak velocity for the same index time; the modified sine law produces lower peak acceleration. Choice depends on the dominant dynamic constraint.
