Precision Sintered Planet Carriers
High-precision powder metal planet carriers engineered for reliable performance in planetary gear systems — manufactured to tight tolerances from prototype through to full mass production.
A Critical Component in Every Planetary Drive
Planet carriers are the structural backbone of a planetary gear system — holding the planet gears in precise radial and axial alignment as they orbit the sun gear within the ring gear. The dimensional accuracy and mechanical integrity of the carrier directly determines the smoothness, efficiency, and service life of the entire gear train.
Sintered planet carriers are manufactured through powder metallurgy, allowing complex carrier geometries to be produced as near-net-shape components with consistent wall thickness, bore concentricity, and pin hole positioning. This process delivers high repeatability at volume — critical for applications in automotive drives, household appliance motors, and industrial actuators where thousands of identical units are required.
At Wisma Technology, we supply sintered planet carriers to your exact engineering drawings through our established network of qualified manufacturing partners. We support your project from initial design feasibility review through prototype sampling to certified mass production supply.
Why Choose Sintered Planet Carriers
Tight Dimensional Tolerances
Powder metallurgy delivers consistent bore concentricity and pin hole positioning — critical for proper planet gear alignment and smooth gear train operation.
High Repeatability at Volume
Die-compaction ensures every carrier produced is dimensionally identical — essential for high-volume automotive and appliance production lines.
Complex Geometry Capability
Integrated features such as pin bores, stepped profiles, and mounting flanges can be formed directly during compaction, reducing secondary operations.
Cost-Efficient at Scale
Near-net-shape production with minimal material waste delivers a competitive per-unit cost compared to machined or cast alternatives at mass production volumes.
Available Configurations
All planet carrier types are manufactured to your exact drawing specifications and dimensional requirements.
Output Carriers
Output planet carriers transmit the combined torque of the planet gears to the output shaft or hub of the planetary drive. They are designed to handle the full output torque of the gear system and must maintain precise geometry under load. Our sintered output carriers are manufactured to your drawing with tight bore and pin hole tolerances to ensure reliable, long-life drive performance.
Custom Carrier Designs
Beyond standard output carrier configurations, we support fully custom planet carrier designs to your engineering drawings — including multi-stage carrier assemblies, integrated flange designs, and carriers with specific pin bore patterns or stepped profiles. Our feasibility review process ensures your design is optimised for powder metallurgy production before tooling is committed.
Sintered Planet Carrier Materials
Material is selected based on your torque, load, environment, and application requirements — we advise during feasibility review.
Iron-Based Sintered
The primary material choice for sintered planet carriers, offering high mechanical strength, good dimensional stability under load, and excellent cost efficiency at volume. Composition — including carbon and alloying element content — is tailored to your torque and fatigue requirements. Suitable for the majority of automotive, household appliance, and industrial planetary drive applications.
Stainless Steel Sintered
Selected for applications requiring corrosion resistance or operation in humid, wet, or chemically exposed environments. Sintered stainless steel planet carriers offer reliable mechanical performance with the added benefit of oxidation resistance, making them suitable for outdoor, food-adjacent, or marine-influenced drive applications.
Applications for Sintered Planet Carriers
Our sintered planet carriers are used in compact, high-torque planetary drives across multiple sectors worldwide.
Automotive
Power window drives, seat adjustment motors, electric power steering systems, and HVAC actuators requiring compact planetary gear trains with consistent, high-volume output carriers.
Household Appliances
Washing machine drive units, robotic vacuum cleaners, stand mixer transmissions, and motorised blind systems where compact planetary drives require precision-made carriers.
Industrial
Gear reducers, actuators, conveyor drives, and precision motion control systems requiring reliable planetary carriers with consistent geometry across long production runs.
Power Tools
Cordless drills, electric screwdrivers, and impact drivers where compact multi-stage planetary gearboxes require tight-tolerance sintered carriers for reliable torque transmission.
