The PLR series is an economy rotary flange pulley drive output precision planetary gearbox. Standard profile pulleys are available for all sizes. Accuracy is down to less than 10arc minutes. The PL series features lower inertia, lower size and weight, quieter operation, reduced backlash, increased efficiency and greater mounting versatility.

The Apex PSII series is the newest revision of the P series. The PII series design has been optimized for higher accuracy, lower weight and length, and greater motor mounting versatility. The PSII 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.

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.
