DynaGear Eco Series
DynaGear Eco is a cost-optimized right-angle hypoid solution that delivers high performance at an efficient price, making it ideal for servo applications requiring low torsional backlash and high efficiency in a compact design. Engineered with optimized hypoid gears, it ensures high torque transfer with backlash as low as <6 arc-min. Tapered roller bearings enhance durability and absorb high loads, while the lightweight aluminum housing provides stability across three available frame sizes.
Standardized output mounting options include solid and hollow shafts, offering versatility for various applications. Designed for convenience, DynaGear Eco is compact, maintenance-free, and features lifetime lubrication for long-term reliability.
