Linner Gears supplies miniature planetary gearboxes and custom compact gear assemblies for applications requiring high reduction ratios, torque density, and controlled motion in limited space. We review motor interface, ratio, load, speed, duty cycle, dimensions, materials, quantities, and inspection requirements before production.
Miniature Planetary Gearbox Solutions
Compact Planetary Gearboxes
Miniature planetary gearboxes for space-constrained motion systems, specified around required ratio, output torque, speed, package size, and service conditions.
Motor-Integrated Gearheads
Planetary gearheads reviewed for motor interface, input coupling, mounting pattern, shaft configuration, and overall package dimensions.
Custom Planetary Assemblies
Custom sun gears, planet gears, carriers, internal ring gears, shafts, housings, and assembled transmission components produced to customer requirements.
