Actuator and joint housings that hold the motion stack.
Bearing seats, motor pilots, gearbox patterns and structural datums must behave as one interface. We review the complete relationship before quotation—not only the outside shape.

The drawing is useful but optional for first contact. Engineering can request the controlled file securely.
Factory-direct reviewRequired contact fields are clearly marked.
THE MOTION STACK
Control the interfaces in the order assembly depends on them.
Motor pilot
Pilot diameter, face runout and bolt-circle relationship.
Gearbox interface
Coaxial location, flange face and assembly clearance.
Structural datum
Mounting planes and patterns tied to a repeatable datum scheme.
COMPONENT FAMILIES
Different forms. The same interface discipline.
Annular joint housings
Large concentric bores, bearing seats, bolt patterns and weight-reduction pockets.
Compact actuator bodies
Motor, gearbox, sensor and structural faces controlled from a coherent datum system.
Yokes and interface brackets
Load paths, pivot bores, stiffness, clearance and service access defined by the drawing.
INSPECTION STRATEGY
Measure the relationship—not isolated dimensions.
Inspection scope follows the released drawing and agreed quotation. Critical joint-housing features may require CMM evidence, bore measurement, positional checks and runout verification.
BUYER VERIFICATION
Factory evidence before project commitment.
Verify certification and assessment scope against the legal entity, site and requested project.
Request remote factory auditSupply scope: machined metal structural parts.
Included: drawing-defined housings, flanges, bearing-seat bodies, yokes, brackets and interface components. Excluded unless separately confirmed: motors, bearings, gearboxes, encoders, electronics, wiring, complete actuator assembly and product R&D.
DIRECT ANSWERS
Before the actuator drawing arrives.
What actuator and joint housings can KEC Tour review?
Drawing-defined annular joint housings, bearing-seat bodies, motor and gearbox interfaces, compact actuator shells, yokes, flanges and structural mounting components.
Which drawing details matter most?
Specify bearing fits, pilot diameters, bolt patterns, datums, runout or positional controls, material condition, finish boundaries and required inspection evidence.
Do you supply complete actuators or robot joints?
The standard scope is machined metal structural components only. Motors, bearings, gearboxes, encoders, electronics, wiring and complete assembly are excluded unless separately confirmed.
How are concentric features verified?
Inspection may include CMM measurement, bore gauges, roundness or runout checks, positional verification and documented first-article results according to the released drawing.
