Weld-On Hubs

Weld-On Hubs for Australian Custom Shaft Mounting

Weld-on hubs are precision-machined hub bodies designed to be welded onto custom drive components, fabricated pulleys, and one-off shaft mounting requirements — providing standard-pattern bores (typically Taper Lock or Mi-Lock) on otherwise non-standard components. For Australian fabricators, custom equipment manufacturers, and engineering workshops producing specialty drive components, weld-on hubs let you use standard bushing systems with custom-designed pulleys, sprockets, and drive elements. AIMS Industrial supplies weld-on hubs for trade and industrial customers.

How weld-on hubs work

The hub is a precision-machined steel body with the standard tapered bore that matches Taper Lock or Mi-Lock bushes. The hub is supplied with a flat outer face that's welded to the custom component (a custom pulley, drum, or fabricated drive element). After welding, the standard bushing fits into the hub bore — providing a standard mounting interface on the custom component. The result is custom drive components that use standard interchangeable bushing systems for shaft mounting.

Where weld-on hubs earn their place

• Custom pulleys and drums — fabricated belt pulleys for specific drive ratios or specialty applications
• Custom sprockets — non-standard sprocket profiles for specialty equipment
• Conveyor head and tail drums — fabricated drums with standard bushing interfaces
• One-off drive components — prototype and small-quantity custom drive components
• Equipment retrofits — adding standard bushing interfaces to existing custom equipment
• Mining and industrial equipment — custom drive components for specific operating requirements

The hub types we stock

• Taper Lock weld-on hubs — bored for the standard Taper Lock bushing system. See our Taper Lock bushes
• Mi-Lock weld-on hubs — bored for the Mi-Lock bushing system. See our Mi-Lock bushes
• Custom-bore weld-on hubs — for specific bushing systems on indented orders

Sizing — match to bushing series and component

Weld-on hub sizing has two dimensions:

• Bushing series — must match the intended Taper Lock or Mi-Lock series (1108, 1610, 2517, 3020, etc.)
• Outer diameter and width — sized to suit the welding to the custom component

Larger bushing series provide higher torque capacity but require larger components to accept the hub. Match bushing series to the drive's torque requirement.

Welding considerations

Welding the hub to the custom component requires:

• Correct alignment — the hub bore must be coaxial with the custom component's centre of rotation
• Appropriate weld procedure — full penetration welds for high-torque applications, fillet welds for lighter loads
• Heat distortion control — welding can distort the hub bore; final boring after welding may be required for precision
• Material compatibility — match weld procedure to the hub material (typically mild steel) and the custom component material

For high-precision applications, machine the hub bore to final dimensions after welding to correct any heat-induced distortion.

Brands stocked at AIMS

Weld-on hubs are stocked from quality power transmission manufacturers across the standard Taper Lock and Mi-Lock bushing series. For specific OEM-pattern hubs or large-quantity orders, sourcing through our distribution channels covers most options.

Companion ranges at AIMS

Weld-on hubs sit alongside our broader power transmission range — see Taper Lock bushes, Mi-Lock bushes, shaft collars, and turning inserts for the related products.
