Dual-Flanged Design
Unlike a conventional wheel hub with a mounting flange on only one side, this assembly features two matching four-bolt flanges welded to a central steel tube housing. The dual-flange configuration provides mounting points on both ends, creating additional flexibility for connecting wheels and other rotating components. The center tube is hollow, allowing the hub to slide over a straight live axle or accommodate a compatible internal bearing arrangement.
Key Features
Two Four-Bolt Flanges
The assembly includes two matching flanges with four evenly spaced mounting holes. This design provides secure attachment points on both sides of the hub.
Durable Steel Construction
The flanges and center housing are manufactured from steel to provide strength and dependable performance in light-duty equipment applications.
Pre-Installed Mounting Hardware
Four zinc-plated hex bolts with lock nuts are installed on one flange, helping simplify wheel placement and assembly.
Hollow Center Bore
The open center bore allows the hub to slide over a compatible straight axle or work with an internal bearing configuration, depending on the equipment design.
Welded Assembly
Both flanges are welded to the central steel housing to create a complete, ready-to-install hub assembly.
Common Applications
Dual-flanged wheel hubs can be used in several types of light-duty vehicles and equipment, including:
- Go-karts
- Mini bikes
- Utility carts
- Small agricultural machinery
- Material-handling equipment
- Custom utility vehicles
- Specialty trailers and mobile equipment
The hub’s suitability for a specific application depends on its dimensions, axle configuration, bolt pattern, bearing requirements, operating speed, and expected load.
Benefits of a Dual-Flanged Hub Assembly
The primary advantage of a dual-flanged design is its versatility. With mounting surfaces on both sides, the hub can support equipment designs that require a wheel, sprocket, brake component, or another rotating part to be attached to either end.
Additional benefits include:
- Flexible two-sided mounting
- Straightforward wheel installation
- Secure four-bolt connection
- Compatibility with various light-duty axle arrangements
- Durable, compact steel construction
- Pre-installed hardware for easier assembly
Selecting the Correct Wheel Hub
Several dimensions and operating requirements should be confirmed before selecting a wheel hub assembly:
- Center bore diameter
- Axle diameter and configuration
- Flange diameter
- Bolt-circle diameter
- Bolt size and thread
- Overall hub length
- Wheel offset and clearance
- Bearing type, if required
- Maximum radial and axial loads
- Expected operating speed
Wheel hubs should not be selected by appearance alone. Verifying these specifications helps ensure proper alignment, secure mounting, and reliable equipment performance.
