1. High precision backlash < 5 arc, Min, Ip65 design 2. Processing by ultra precision machine and advanced gear grinding craft the gear precision can be controlled under is04 to guarantee the gearboxes exceptional accuracy and efficiency. 3. Choosing low carbon alloy forged steel as the primary component of the gear, The hardness can reach hrc60 by deepen harden of carburizing heat treatment to ensure gear strength and lifetime. 4. With integrated design of caged planet carrier along with the output drive shaft to realize high rigidity and high precision. 5. Planet, Gear bearings use full Roller bearing with needle elements cage to increase gearboxes output torque and rigidity 6. Applicable with any/all make servo motor around the world 7. No grease leakage requiring no maintenance by using synthetic lubricating grease and ip65 protection design.
