Planetary Gearbox
At PJM Automation, we specialize in custom planetary gearboxes and bespoke planetary gear units tailored to meet the exact needs of global OEMs, automation integrators, and industrial machinery manufacturers. Whether you require a custom planetary gear reducer for AGV systems, a high-torque planetary gearbox for machine tools, or a compact planetary gear drive for robotics, we deliver engineered solutions designed for your application.
We are one of the leading planetary gear motor manufacturers in China. With many years of experience in the motion control industry, we specialize in a wide range of motors and actuators. We can provide customized services for users in different industries to ensure customer satisfaction.
Planetary gearbox are also named planetary gear reducer, planetary gearhead. It is a system of gears including three main components: Sun Gear, Planet Gears, ring gear. Adapt to your installation space, we design and offer inline planetary gearbox, right angle planetary gearbox, rotation table and full customed AGV gearbox.
● Typical gear ratios: 3:1 to 10:1 for standard single-stage. Multi-stage custom options up to 50:1 or more.
● Planetary stages: 1-stage, 2-stage, 3-stage, or more depending on torque/ratio requirements.
● Inline input/output shafts or right-angle designs.
● Fixed foot mounting or flange/shaft mounting.
● Custom shaft diameters and keyways, as requested by your equipment design.
● High radial/axial loads accepted by using taper-roller or cross-roller planetary bearings.
● Backlash control options for servo or precision motion systems.
● Hardened steel gears, non-ferrous or plastic gears for noise-sensitive applications.
● Housing: cast/machined steel, aluminum, or stainless steel for corrosive environments.
● Lubrication: synthetic oil, food-grade grease (for packaging machines), low-temp lubricant for outdoor use.
● Optimized gear geometry and bearing selection ensure high efficiency and long service life.
● Lifetime lubrication and minimal maintenance ensure reliable global operation.
Autonomous guided vehicles (AGVs), warehouse shuttles, and intralogistics systems benefit from compact high-torque planetary gearboxes. Our custom solutions reduce length by up to 40% compared to standard designs, improving maneuverability and efficiency.
Robotic arms, delta robots, and precision motion systems demand minimal backlash and high repeatability. We provide precision planetary gear units and reducers configured for servo motors and high-precision drives.
In steel plants, cement mills, or mining equipment, planetary gearboxes must handle extreme loads and harsh environments. Our custom designs feature high-load bearings, sealed housings, and corrosion-resistant materials.
Compact drives for CNC machines, packaging lines, or food-grade applications often require customized mounting and hygiene-compliant design.
We offer food-grade lubrication and stainless housings to meet your industry standards.
Over 10 years of experience manufacturing planetary gearboxes and gear units.
In-house gear cutting, hardening, grinding, and assembly.
Full support for global procurement: export documentation, packaging, and compliance.
Competitive pricing and reliable delivery.
Trusted by OEMs across logistics, robotics, machine tools, and heavy machinery.
