Product Description

ALF inline planetary gearheads are designed to bolt-on linear actuator drive systems or cartesian robotics to shorten powertrain length. Dynamic balanced collar clamping mechanism to actuator and motor shaft ensuring interfaces concentricity and zero slip power transmission at high speed. High quality gears and components are utilized to create compact and rigid unit with low backlash and maintenance-free operation.The VLF compatible with 400W and 750W servo motors, offering reduction ratios of 5:1 and 9:1, respectively.
