Rotary Indexer Systems
Nexen’s Rotary Indexer Systems leverage the innovative Roller Pinion technology, alongside a patented design featuring a precision-grade bearing and drive mechanism.
Encased within a robust housing, these systems offer unparalleled accuracy, rapid acceleration, high speed, and impressive load capacity. They can be customized to meet diverse application requirements.
The standout feature of Nexen’s Rotary Indexer Systems is their ability to initiate and stop operations at any incremental position. By simply loading a new servo drive program, users can effortlessly adjust the motion profile. Unlike conventional cam-driven systems, Nexen’s Rotary Indexers can handle peak torque inputs at any moment, resulting in remarkably faster indexing times, potentially up to twice as fast. Experience the superior performance and flexibility of Nexen’s Rotary Indexer Systems for your indexing needs.
The Nexen Rotary Indexer Advantage
- High Indexing Precision
With an indexing precision of up to ± 11 ArcSec and repeatability of up to ± 1.2 ArcSec, Nexen’s Indexers offer unmatched mechanical system capabilities.
- Zero Backlash
Unlike other mechanical drive systems, Nexen’s Indexers offer zero backlash options from the motor through the driven load.
- High Load Capacity
Nexen’s Rotary Indexers can handle loads up to 1575 kN (on PRD) by utilizing precision grade, high load capacity cross-roller bearing,
- High Output Torque
Rotary Indexers have a maximum acceleration torque of up to 4,811 Nm and a Nominal torque of up to 2,625 Nm.
- High Speed
Indexers are designed for speeds up to 304 RPM.
- Large Open Center
The Indexer’s design allows for a large open center for more application possibilities.
- Smooth in Motion
Combining Nexen’s RPS technology with a preloaded cross-roller bearing and an integrated motor/precision gearhead gives a rigid, smooth system.
Differences between PRD and CRD Systems
Precision Ring Drive Systems (PRD)
The PRD system is built on a precision machined steel plate with a guard that shrouds the gear and pinion. Numerous options are available, including a low-backlash Planetary Gearhead or zero backlash Nexen Harmonic Gearhead to drive pinion. Available output bolt circle diameters of 400, 750, 1100, or 1500 mm.
Compact Precision Ring Drive Systems (CRD)
The CRD system is built on a rigid, sealed cast iron housing that completely encloses the gear and pinion. Numerous options are available, including motor/gearbox-ready input, pre-installed low-backlash Planetary Gearhead, or pre-installed zero backlash Nexen Harmonic Gearhead to drive pinion. Available output bolt circle diameters of 150, 250, 350, or 550 mm.
