Compact Ring Drive

Compact Drive Ring

Based on Nexen’s innovative Roller Pinion technology, the Compact Ring Drive (CRD) system comes complete with a precision grade bearing and drive mechanism in a sealed housing. Freely programmable, the three drive design configurations allow the CRD to be optimized for high speed, high torque or both depending on the application. With a 250 or 350 mm dial plate bolt circle diameter and a large open center, users can optimize performance in a small space.

 

 

High Indexing Precision

With an indexing precision up to ± 30 ArcSec and repeatability up to ± 5.1 ArcSec, Nexen’s CRD offers unmatched mechanical system capabilities.

 

High Output Load Capacity

With the precision grade, high load capacity crossroller bearing, the CRD can handle loads up to 108 kN.

 

High Speed

The CRD can handle speeds up to 225 RPM.

 

The PRD Advantage

 

The Precision Ring Drive System (PRD) simplifies the selection process and includes all components needed for your rotary drive system. The PRD system offers all the great features of our other advanced RPS technology and opens up new design possibilities to next generation machines.

 

High Indexing Precision

With an indexing precision up to ± 11 ArcSec and repeatability up to ± 1.2 ArcSec, Nexen’s PRD offers unmatched mechanical system capabilities.

 

High Load Capacity

The PRD table is supported by a high capacity crossroller bearing rated for loads up to 1575 kN.

 

High Speed & Acceleration

The PRD is capable of speeds of up to 94 RPM. Unlike traditional cam driven systems, the PRD can handle peak torque inputs at any time. This allows for indexing times up to 2x faster than the competition.
