PSIIR-Series High Precision Right Angle Planetary Gearboxes


The Apex PSIIR series is a high precision economy right angle planetary gearhead. The PIIR series design has been optimized for higher accuracy, lower weight and length, and greater motor mounting versatility. The PSIIR features an industry standard metric output flange, carbon steel and aluminum construction, precision bonded housings for greater accuracy and faster, more precise assembly, and laser welded pinions for the highest concentricity two part assemblies. Low profile planetary gearing and precision ground spiral bevel right angle gears provide smooth, quiet operation and accuracy.
