Patented sealing system featuring a TiCN coated shaft surface that eliminates leakage and increases 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% providing benefits of improved smoothness, decreased noise and backlash, and increased torque capacity. The helix angle is carefully chosen to gain these advantages while not producing excessive axial forces.
Planet gears turn on solid uncaged needle roller bearings for increased stiffness and the maximum number of contact points. Hardened thrust washers allow the close control of clearances in order to further reduce 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 heat 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.
The helical internal ring gear is machined directly into the pulley itself for perfect concentricity and maximized internal diameter. The possibility to optimize the tooth number and module allows the torque capacity to be increased considerably.
Lubrication by synthetic Nyogel 792D grease for smooth operation over the whole service life, regardless of mounting orientation. Sealed to IP65 standard for protection and maintenance-free performance.
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. Precision ball bearings are oversized and optimally positioned to maximize the load capacity and service life of the unit.
Extremely compact design allows the use of short motor adapter that allows fitment in the most challenging locations. Simple modular design readily adapts to any motor in minutes.
One-piece carrier and mounting flange assures concentricity and alignment of all the rotating parts and the strength and rigidity of the whole system. Supporting two oversized bearings, the whole structure can withstand high radial loads through torque and belt tension.
