DynaGear Series

High Performance for Dynamic Servo Applications

DynaGear is designed for highly dynamic servo applications where precision, efficiency, and compactness are essential. Its optimized hypoid gears ensure smooth, high-torque transfer with minimal backlash of less than 2 arc-min. Tapered roller bearings on both the input and output sides absorb high radial and axial loads, enhancing durability and extending service life. The planetary input stage allows for higher gear ratios, while the lightweight, one-piece aluminum housing provides exceptional stability under load.

With versatile mounting options, including solid shaft, hollow shaft, dual shaft, and robot flange, DynaGear adapts to various installation needs. Its maintenance-free, lifetime lubrication ensures reliable operation, and its compact design saves valuable space in constrained environments.
