28mm Planetary Reducer Copywriting
28mm Precision Planetary Reducer | Compact Size, High Torque, Precise Transmission
Powerful performance built into a compact frame.
The 28mm planetary reducer features a
φ28mm ultra-small outer diameter and lightweight design under 100g. It delivers efficient power transmission in limited spaces, serving as an ideal drive core for miniature automation equipment.
Core Advantages
-
Precise Transmission & Low Backlash
Adopts 20CrMnTi carburized and quenched hardened gear surface with aerospace-grade grinding precision. Single-stage backlash ≤15 arcmin for accurate positioning and zero transmission clearance.
-
High Efficiency & High Torque
Multi-stage planetary gear meshing, with a maximum transmission efficiency of 95%. Output torque up to 4N·m, enabling high-load driving with low-power motors and energy saving.
-
Stable Performance & Long Service Life All-steel hardened gears matched with premium bearings, running noise ≤60dB with smooth operation. Resists high temperature from -20℃ to +85℃ and wear, service life over 8000 hours.
-
Wide Compatibility & Easy InstallationRich gear ratio options from single-stage 3.7/5.2 to four-stage 1296. Perfectly compatible with 28mm stepper, brushless and servo motors. Standard round flange and mounting holes for plug-and-play installation.
Application Scenarios
Widely used in medical equipment (dental chairs, infusion pumps) , service robots, smart home products (electric curtains, door locks) , automated production lines and precision instruments. It provides an optimal solution for precise motion control in narrow installation spaces.
