These planetary gear components power compact, high-torque reducers used in robotics and automation, where several planet gears share the load around a central sun gear. The arrangement delivers high torque density and precise ratio control within a small, coaxial package that fits neatly into joint actuators.

Each planet, sun and ring component is milled to tight tolerances so the load balances evenly and backlash stays minimal. Gear measuring verification of profile, pitch and alignment ensures the set runs smoothly and repeats position accurately over countless operating cycles. Provide your torque and backlash targets, and our team will specify the planet, sun and ring set that meets your servo reducer needs.

• High Torque Density: Multiple planets share the load for compact yet powerful reducers.
• Coaxial Compact Design: Fits neatly into robotic joint and actuator envelopes.
• Low Backlash: Tight tolerances keep backlash minimal for accurate positioning.
• Balanced Load Sharing: Even tooth contact between planets lengthens service life.
• Precise Ratio Control: Accurate tooth counts deliver the exact reduction you require.
• Verified Accuracy: Tooth profile and pitch are checked on a gear measuring centre.

Used in robot arm joints, servo reducers, CNC rotary tables and automation actuators that demand high torque in a compact frame.

They also serve medical robotics, aerospace actuators and precision handling systems that need accurate, repeatable motion.

Components are bagged in sets, rust-protected and packed with dividers so the matched parts stay together and undamaged.

Every order includes an ISO 9001:2015 certificate and inspection data, backed by a twelve-month guarantee against manufacturing defects.

Set-based bagging and lot control keep matched components together, with worldwide shipping support provided by our export team.
