The Apex AD series High Torque, Low backlash COMPACT Helical, One Piece Plantary Cage Design Provides the Stiffest and Most Accurate Rotating Flange Design on the Market Today. Superior Accuracy of less than 1 arc-min and as SHORT as 70mm (Flange to Flange), The Apex AD fits into the smallest spaces.
The Apex ADR version has a 90° input via spiral bevel gear. Features an extremely short, rigid housing and full compatibility to any motor. The Apex ADS version features a specially designed input shaft with key and treaded hole. Easy to drive via timing belt pulley or coupling. It has been specifically created to increase design flexibility and space saving for motor mounting. It is ideal for highly dynamic cyclic duty or continuous running application.

Patented sealing system featuring a TiCN coated shaft and increses service life to over 30,000 hours. The high tech coating, with a surface quality of 0.2 µ m and hardness of 3700 Hv. Interfaces with our proprietary seal, decreasing wear and running temperature. 
Helical Gear Design
Helical gearing increases the tooth to tooth contact ratio by as much as 33%, Benefits include increased torque capacity, ultimate smoothness, lower backlash and decreased noise. The helix angle is carefully chosen to gain these advantages while not producing excessive axial forces.
Planet gears rotate on solid uncaged needle roller bearings for increasing stiffness and the maximum number of contact points. Hardened thrust washers allow the precise control of clearances in order to eliminate backlash.
Industry-leading gear performance is attained with our HeliTopo technology. Ease off of the tooth profile and lead crowning optimizes the gear mesh under load and achieves maximum tooth surface contact.
Our in house plasma nitriding treatment process allows the hardness of the gear flanks to reach over 900Hv for superior wear resistance and still maintain a core hardness of 30HRc for toughness and resistance to shock loading.
One-piece carrier and output housing ensure 100% concentricity and alignment of all the rotating components. One-piece construction increases strength, rigidity and system reliability.
Lubrication by synthetic Nyogel 792D grease for smooth operation over the whole service life. Sealed to IP65 standard for ingress protection and can be mounted in any orientation.
Patented planet carrier design mounts the sun gear bearing directly into the planet carrier in order to eliminate misalignment. This exclusive design offers great advantages in decreased noise, vibration and transmission errors and losses.
Triple-split collet and dynamically balanced set collar clamping system for efficient power transmission. Perfect concentricity from one-piece sun gear reduces backlash and allows higher input speeds.
