Milwaukee ForgeTech manufactures custom forged hubs for demanding industrial equipment and mechanical systems. We produce forged hubs designed to transmit torque, support rotating components, and perform reliably under high loads and challenging operating conditions.
Forged Hubs Manufacturer
Milwaukee ForgeTech manufactures custom forged hubs for demanding industrial equipment and mechanical systems. We produce forged hubs designed to transmit torque, support rotating components, and perform reliably under high loads and challenging operating conditions.
We have a long history producing keyed hubs, splined hubs, flanged hubs, coupling hubs, and custom hubs for multiple industries. If you have a drawing or specification, request a quote or upload your file to get started.
What Are Forged Hubs?
Forged hubs are central components used to connect rotating elements such as shafts, gears, wheels, or couplings. They provide a mounting point and interface between components, allowing torque and motion to be transferred through the system. Hubs are often used as the interface between shafts and mounted components such as gears, wheels, or couplings.
Typical hub designs include flanged hubs, keyed hubs, splined hubs, and custom geometries produced to meet specific system requirements. Hubs are often machined after forging to achieve precise bores, keyways, and mounting features.
We produce forged hubs to customer specifications based on load, fit, and service requirements.
Why Forging Is Used for Hubs
Forging is used for hubs because these components are often subjected to:
high torsional loads
repeated loading cycles
stress concentration at keyways or splines
shock and impact loading
The forging process improves the internal structure of the steel, producing hubs that perform reliably in high-load and high-wear environments.
Materials for Forged Hubs
Material selection depends on torque requirements, fit, and wear conditions.
Common alloy steels used in forged hubs include:
4140 Alloy Steel
Used when strength and toughness are required throughout the entire component.
through-hardenable
high strength and fatigue resistance
suitable for load-bearing and torque transmission
8620 Alloy Steel
Used when a wear-resistant surface and a tough core are required.
commonly used with carburizing
hard outer surface after heat treatment
tough internal core
Selecting between 4140 and 8620 depends on whether the hub requires uniform strength or a hardened surface for wear resistance.
How Forged Hubs Are Manufactured
We produce forged hubs using hammer forging and press forging, depending on geometry, tolerances, and production requirements.
Hammer forging is used for short- to medium-volume runs and more complex geometries.
Press forging is used when controlled deformation and tighter tolerances are required.
Applications for Forged Hubs
Forged hubs are used in equipment that operates under high load and demanding conditions, including:
industrial machinery
power transmission systems
construction equipment
mining equipment
These components are critical for connecting rotating elements and maintaining reliable torque transfer.
Capabilities and Production Range
We manufacture forged hubs within the following general range:
forging weights from approximately 2 to 100 pounds
short- to medium-volume production
custom die design and engineering support
Best suited for custom hubs within the 2-to-100-pound range and short- to medium-volume production.
Forged hubs can be supported with secondary machining, boring, and heat treatment as required.
