FingerTech Lightweight Twist Hubs

Designed for combat robotics, FingerTech’s Lightweight Twist Hubs offer a reliable, low-cost solution to secure your wheels while reducing weight for enhanced robot performance.

The FingerTech Lightweight Twist Hubs are perfect for mounting your FingerTech Foam Wheels and provide the same great benefits as the aluminum versions but at a lower weight and price point. These hubs are ideal for combat robots where every gram counts, and they help you get the most out of your robot without compromising performance.

Why Choose FingerTech Lightweight Twist Hubs?
  • Affordable and Lightweight: These hubs are injection-molded from glass-fiber nylon, offering strength without the heavy cost of metal alternatives.
  • Enhanced Performance: The lightweight nature reduces the overall weight of your robot, which is critical in weight-class competitions where every ounce counts.
  • Secure Mounting: The custom locking washer ensures your foam tire stays securely in place, while lengthwise fins prevent tire slippage even without compression. Includes a metal threaded insert so you can really crank down the setscrew.
  • Simple Installation: The hubs are easily mounted with FingerTech Foam Wheels (or compatible Lite Flites), and a strong 8-32 setscrew secures the hub to the motor shaft for a tight fit.
Perfect Fit for Combat Robots

These hubs are ideal for high-impact combat robotics, where foam wheels are preferred for absorbing shocks and protecting your drive motor gearboxes. These hubs provide a simple and efficient way to mount your tires.

Lightweight Twist Hubs are available in two sizes (0.50in and 0.75in) and are perfect for reducing robot weight, optimizing speed, and improving overall maneuverability. However, please note that the lightweight version is only available with a 3mm shaft bore, so make sure to choose the correct size for your setup: bore must match the motor shaft, and thickness (width) must match your wheel thickness.

These hubs are a great way to enhance your robot’s performance without breaking the bank. Ready to reduce weight and increase speed? The FingerTech Lightweight Twist Hubs will give you the competitive edge you need in the arena!

 

Features
  • Lightweight Design: Injection-molded from glass-fiber nylon, these hubs are designed to be both durable and lightweight, reducing overall robot weight.
  • Cost-Effective: More affordable than aluminum hubs, providing a high-performance solution without the higher cost.
  • Secure Wheel Mounting: The custom locking washer ensures a secure fit for FingerTech Foam Wheels, preventing slippage during high-impact battles.
  • Easy to Install: Simple installation process with a strong 8-32 setscrew to secure the hub to the motor shaft, ensuring a tight and reliable fit.
  • Upgraded Bore: Includes a metal threaded insert so you can really crank down the setscrew and add threadlocker.
  • Upgraded Washer: Stronger washer indentations so pliers don’t punch through when locking the washer to the hub.
  • Optimized for Combat Robots: Designed for high-impact environments, these hubs are perfect for absorbing shocks and protecting your robot’s drive motor gearboxes.
  • Multiple Size Options: Available in 0.50in (thin) and 0.75in (wide) with a 3mm shaft bore, these hubs are compatible with FingerTech Foam Wheels and Lite Flites.
  • Improved Durability: Lengthwise fins on the hub prevent the tire from spinning, even when not fully compressed by the washer.
 
Maintenance & Parts
  • Match bore to shaft: These hubs are 3mm bore. If you need to enlarge, drill carefully and keep the bit perfectly square. Do not exceed 6.35mm (0.25in). An oversized or off-axis bore will cause wobble, set-screw loosening, and premature tire wear.
  • Set the setscrew on the flat: Align the 8-32 setscrew with the flat on the D-shaft—not the round. Tighten firmly, then add a drop of medium threadlocker. Recheck after the first match; retorque as needed.
  • Washer engagement: Press the locking washer fully, then twist 90° to lock. Ensure the washer tabs seat cleanly; if the tire isn’t compressed, the fins prevent slip, but proper compression gives maximum security.
Tip: If you notice wheel slip or wobble, inspect bore fit, verify the setscrew is on the flat, and reapply threadlocker. Replace damaged washers or stripped setscrews before the next event.

Frequently Asked Questions (FAQ)
 
What are FingerTech Lightweight Twist Hubs made of?

The Lightweight Twist Hubs are injection-molded from glass-fiber nylon, offering a balance of strength and low weight. They’re ideal for combat robotics where every gram counts.

Can I use these hubs with any wheels?

These hubs are designed specifically for use with FingerTech Foam Wheels. Note that 0.50in hubs only fit 0.50in wheels, and 0.75in hubs only fit 0.75in wheels. These sizes are not cross-compatible, so always match hub and wheel sizes properly for a secure fit.

How do I install the Twist Hubs?

The hubs are secured using an 8-32 setscrew and a custom locking washer. Press the washer in and rotate it 90° to lock or release, ensuring your tire stays in place. For reference, see the FingerTech installation video.

What is the weight of the Lightweight Twist Hubs?

The Thin (0.50in) version weighs 5.6g (0.20oz), while the Wide (0.75in) version weighs 7.1g (0.25oz). The lightweight design helps reduce your robot’s total weight for better performance.

What shaft bore sizes are available for the Lightweight Twist Hubs?

The Lightweight Twist Hubs are only available with a 3mm shaft bore. They can be drilled out up to 6.35mm (0.25in) if needed for other motor setups.

Are these hubs compatible with all combat robots?

These hubs are primarily designed for robots using foam wheels. They’re best suited for antweight weight-class competitions and high-impact matches where lighter components provide a competitive edge.

How do I choose between Thin or Wide Twist Hubs?

The Thin (0.50in) hubs are great for tight spaces and when every gram matters. The Wide (0.75in) hubs give more surface contact and stability—0.75in is the more common choice among builders.

Can I use the Lightweight Twist Hubs for high-impact battles?

Yes! These hubs are built to withstand combat robotics impacts, but since they are lighter than aluminum hubs, they may not handle extreme stress as well. Many builders use them as a cost-effective option where weight savings are critical.
