Planetary Gearbox Manufacturer

As a globally leading Planetary Gearbox Manufacturer, TallMan Robotics has accumulated decades of precision transmission technology to create a planetary gearbox product matrix that covers multiple scenarios and meets high requirements, becoming a core component supplier in the fields of industrial automation and high-end equipment manufacturing.

As a trusted planetary gearbox manufacturer, we engineer planetary gear systems built for demanding industrial automation, robotics, and motion control applications. Our inline planetary gearboxes and right-angle planetary gearboxes deliver exceptional torque density, low backlash, and long service life across every duty cycle.

Here In this page, we introduce PET serial Planetary Gear Reducers, you will see technical data,packing, and videos of test as follows:

Industrial automation case studies

AUTOMOTIVE ASSEMBLY : High-cycle torque control on welding positioner arms

A Tier 1 automotive supplier needed consistent positional accuracy across a 3-shift robotic welding line. Existing worm gear units were failing under thermal load and required frequent replacement. We specified a 2-stage inline planetary gearbox at a 64:1 ratio, paired to a 750W servo motor. The low-backlash design held ±0.02° repeatability through 18 million cycles over 14 months without gearbox service intervention.

Downtime cut by 73%

PACKAGING & CONVEYING  : Compact servo gearbox integration for high-speed pick-and-place

A food packaging OEM required a compact planetary gear reducer for a delta-robot pick-and-place cell running 120 cycles per minute. Footprint constraints ruled out conventional helical gearboxes. Our right-angle planetary gearbox offered a 40% smaller envelope at equivalent output torque. Integration was completed within the existing motor flange standard, reducing retrofit time significantly.

40% size reduction achieved

Frequently asked questions about Planetary Gearbox

What is a planetary gearbox and how does it work?

A planetary gearbox uses a central sun gear, multiple planet gears, and an outer ring gear to distribute load across several mesh points simultaneously. This coaxial arrangement delivers high torque density and efficiency in a compact footprint, making it the preferred choice in servo and industrial automation applications.

What gear ratios are available?

Our planetary gear reducers cover ratios from 3:1 to 512:1 as standard, achievable through single-stage or multi-stage planetary configurations. Custom planetary gearbox ratios outside this range are available on request for OEM volumes.

How do I select the right planetary gearbox for my servo motor?

Match the gearbox input flange to your servo motor output flange, then size by peak output torque, nominal speed, and required backlash class. Our engineering team can assist with servo gearbox selection using your motor datasheet and duty-cycle profile.

What backlash classes are offered?

We offer standard (≤5 arcmin), precision (≤3 arcmin), and high-precision (≤1 arcmin) backlash classes across our inline and right-angle planetary gearbox ranges. High-precision grades are recommended for CNC, robotics, and closed-loop positioning axes.

What is the typical lead time for planetary gearbox orders?

Standard catalogue planetary gearboxes ship within 3–5 business days from stock. Custom gear ratios, modified flanges, or special output shaft configurations typically require 3–4 weeks. Volume OEM programs can be supported with scheduled releases and safety stock agreements.
