Schaeffler (SHA0.DE): Humanoid Robotics Exposure

Where it fits in the robot

A disclosed partnership with Humanoid includes actuator supply. Bearings, transmissions, sensors, and manufacturing capabilities support an integrated motion offering.

What the evidence establishes

Humanoid evidence

The Humanoid partnership supports actuator supply. Separately, Schaeffler disclosed a two-stage planetary humanoid actuator at CES 2026 (linked in the assembly sources). Neither establishes finger or tendon supply.

An explicit humanoid product, development program, application, or partnership. This does not establish revenue, market share, or production volumes.

Keep in perspective

Humanoid partnerships are developing; automotive and industrial operations remain important to the group.

Diversified business exposure. This describes the breadth or role of the business; it is not an investment rating. A robotics product or development announcement does not by itself establish material humanoid revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Housing & mounting flange

A rigid enclosure locates the motor and transfers heat and mechanical loads into the robot link.

Scope of the company links: Integrated actuator developers; a housing is part of the system. These are not verified standalone casting suppliers.

Reduction stage

Reduction trades speed for torque, with power lost to friction and other losses. This example is planetary; humanoids also use strain-wave, cycloidal and other transmissions.

Scope of the company links: Planetary product families include Schaeffler’s disclosed two-stage humanoid actuator, Nidec ABLE and Zhaowei miniature drives. Their designs differ from this illustration. Strain-wave and cycloidal suppliers appear in the broader Joints & gears sector.

Internal ring gear

In this configuration, the outer ring is fixed to the housing. Its inward-facing teeth mesh with the planets and transmit reaction torque.

Scope of the company links: These companies make complete planetary reducers incorporating ring gears; standalone ring-gear supply is not established.

Input sun gear

The motor turns this central gear. It drives the three planet gears that mesh with the fixed ring.

Scope of the company links: Planetary gearbox integration, including the central sun gear. Strain-wave products do not use this mechanism.

Planet gears & pins

Planets spin on carrier pins while orbiting the sun, distributing load across several meshes. With the ring fixed, the ideal reduction ratio is 1 + ring teeth / sun teeth.

Scope of the company links: A planetary reducer product match. This is not a claim of standalone planet-gear or pin supply.

Output carrier

The carrier supports the planet pins and delivers the slower, higher-torque rotation to the robot link.

Scope of the company links: Complete planetary transmission integration, rather than a verified standalone carrier contract.

Output bearing

The output bearing supports and aligns the moving member. Radial, axial and moment capacity depend on bearing type, arrangement and preload.

Scope of the company links: Bearing suppliers supporting rotating joints. Exact bearing type and fit depend on the robot and gearbox design.

Outer bearing race

The outer race locates the bearing in its housing and provides one of the rolling-contact surfaces.

Scope of the company links: Complete bearing manufacturers; their products incorporate races. This is not a list of independent race-ring subcontractors.

Rolling elements & cage

Rolling elements carry loads with low friction; a cage maintains their spacing.

Scope of the company links: Rolling-bearing products integrate rolling elements and cages. Designs may use balls, rollers, or crossed rollers.

Inner race & shaft interface

The inner ring interfaces with a shaft or moving link. Stiffness and precision affect how accurately a robot holds position.

Scope of the company links: Bearing manufacturers with robot-relevant products; a specific inner-race supply agreement is not asserted.
