Replacing LIKEPRECISION RV Cycloidal Reducers and Overhauling Axes J1–J6

Every joint in a CHAIFU robot uses a precision Rotate Vector (RV) reducer built in-house under the LIKEPRECISION brand (上海力克精密). In February 2020, the factory produced its 100000th RV reducer, ensuring dimensional standardization and direct spare availability.

When backlash increases, noise or braking vibration appears, or metal particles are found in gear oil, the corresponding RV reducer (base axes J1–J3 or wrist axes J4–J6) is replaced together with seals and bearings.

We supply genuine LIKEPRECISION RV reducers, CHAIFU SERVO MOTOR units with encoders and brakes, servo amplifiers, controller boards, teach pendants, and dress pack harnesses.
