N-ZAPEX

The N-ZAPEX is a lubricated steel gear coupling of double-engagement design. It transmits torque positively via two externally toothed hubs that engage with two internally toothed sleeves; the two sleeves are bolted together at their flanges with close-fitting bolts. The crowned external teeth can slide and tilt within the internal teeth, so the coupling compensates angular, radial and axial shaft misalignment without transmitting significant restoring forces to shafts and bearings.

As a torsionally rigid coupling, the N-ZAPEX transmits high torques in a small space and suits demanding drives with shocks and load changes. The tooth flanks run in a lubricant that reduces wear and friction. The series is therefore designed for continuous duty in heavy industrial plants that require reliable misalignment compensation and high power density.

As a new generation, the N-ZAPEX (variants XN and XW) succeeds the previous ZAPEX series. REEL supplies the N-ZAPEX including matching toothing and wear parts and supports selection, sizing and replacement.
