Repeat Robotics Scalar Weapon Belt 267-3M-05
Repeat Robotics Scalar Weapon Belt 267-3M-05
The Scalar weapon belt is the exact timing belt spec’ed by Repeat Robotics for the Scalar antweight combat robot kit. Sourced thicker than standard 3mm timing belts for better durability under combat loads, this belt pairs directly with the 18T Scalar weapon pulley for smooth, reliable power delivery from motor to blade. Belts are a consumable in combat — keep spares on hand and you’ll never lose a match to a snapped belt.

The Exact Belt for the Scalar Weapon System
The Scalar weapon belt is the 267-3M-05 timing belt spec’ed by Repeat Robotics for the Scalar antweight horizontal combat robot kit. This isn’t a generic off-the-shelf timing belt — Repeat sources this belt thicker than standard antweight timing belts specifically to handle the shock loads of combat. If you’re running a Scalar, this is the correct belt for your weapon system.
Thicker Than Standard for Combat Durability
Standard 3mm timing belts — including the FingerTech S3M belts commonly used in combat robots — are designed for lighter-duty power transmission. The Scalar weapon belt is sourced thicker to survive the repeated shock loading of a spinning weapon. When your blade takes a hit and the drivetrain absorbs that energy, a thicker belt is less likely to skip teeth or snap outright. That’s the difference between walking away from a match and limping out.
Designed for the Scalar Weapon Stack
The 267-3M-05 designation tells you exactly what you’re working with — 267mm pitch circumference, 3mm pitch, 5mm wide. This belt is designed to work with the 18T Scalar weapon pulley and the Scalar weapon hub as part of a complete, purpose-built weapon drivetrain. The Scalar Weapon Kit ships with two belts — one installed and one spare — because Repeat Robotics knows builders need backups.
Stock Spares Before Your Next Event
Belts are a combat consumable. A hard hit, a tooth skip, or a belt that’s seen one too many matches can put you out of a tournament if you don’t have a spare in your kit bag. Experienced builders keep 2–5 belts on hand. At this price point there’s no reason not to. Order extras now and you’ll never be the builder frantically looking for a belt between rounds.
Compatible Belt Standards
The 267-3M-05 uses a 3mm pitch tooth profile compatible with both HTD3M and S3M pulleys, making it easy to source replacements or verify compatibility with custom designs. The 5mm width is the standard for the Scalar weapon system — do not substitute a wider or narrower belt without confirming pulley compatibility. If you’re building a custom antweight weapon system and want to use this belt, pair it with the Scalar 18T weapon pulley for a proven combination.

Frequently Asked Questions
What does 267-3M-05 mean?
It’s the belt designation — 267mm pitch circumference, 3mm tooth pitch, 5mm wide. That’s all you need to know to confirm compatibility with a pulley or find a replacement. The Scalar weapon system is designed around this exact designation, paired with the 18T Scalar weapon pulley.
How is this belt different from a standard FingerTech S3M belt?
Width, thickness, and Circumference:
- FingerTech S3M belts are 4mm wide — the Scalar weapon pulley uses a 5mm wide belt
- FingerTech doesn’t carry the 267mm circumference — their lineup jumps from 264mm to 276mm, skipping the Scalar’s size entirely
- The Repeat Scalar belt is also thicker than standard S3M belts for better durability under weapon shock loads
How many belts should I keep on hand?
Experienced builders keep 2–5 spares in their kit bag. Belts are a combat consumable — a hard hit, a tooth skip, or a belt that’s seen one too many matches can end your tournament if you don’t have a replacement ready. The Scalar Weapon Kit already includes one spare, but at this price point there’s no reason not to stock more before your next event.
Will this belt work in my custom antweight design?
It will work in any design that uses a 267mm pitch circumference, 3mm pitch, 5mm wide belt with HTD3M or S3M compatible pulleys. If your center-to-center distance and pulley tooth count work out to this belt length, it’s a direct fit. The Scalar uses 93.3mm center-to-center spacing with an 18T motor pulley — if your geometry differs you’ll need to calculate the correct belt length for your design. A belt length calculator can help you work out the math before you order.
Is this belt compatible with HTD3M and S3M pulleys?
Yes — the 3M tooth profile is compatible with both HTD3M and S3M pulleys. The tooth shapes are slightly different between the two standards, but at this pitch and width they’re functionally interchangeable in most antweight applications. The Scalar 18T weapon pulley is the confirmed match for this belt in the Scalar weapon system.
