3mm axle spacers in 1.5mm brass

Millimetre Precision for Axle Adjustment in Your Scaleauto 1/24 Cars

When tuning a 1/24 scale slot car, the smallest details define track behaviour. The 3 mm Brass Axle Spacers with 1.5 mm Thickness from Scaleauto (ref. SC-8111C) are an essential preparation element for precisely adjusting the axial position of wheels, crown gears, and other drivetrain components.

Function and Performance

The axle spacer serves a seemingly simple but technically impactful function: accurately positioning each piece on the axle, eliminating unwanted lateral play and ensuring that crown gears, bearings, and wheels operate in the optimal position. Poorly controlled axial spacing results in vibrations, uneven wear, and a loss of consistency in the car's behaviour.

• Designed for 3 mm diameter axles.
• Thickness of 1.5 mm, allowing fine adjustments and combinable with other spacers.
• Manufactured from brass, a wear-resistant material with good dimensional tolerance.
• Scale: 1/24.
• Scaleauto Reference: SC-8111C.

Compatibility and Installation

These spacers are designed for use in the preparation set of 1/24 scale slot cars with 3 mm axles, common in the range of vehicles and platforms from Scaleauto for Sport track. Multiple spacers can be combined to achieve the exact spacing required for each setup, adapting to both competitive configurations and more standard settings.

Installation is straightforward: they slide onto the axle before placing the piece to be positioned. No adhesive or special tools are required, although it is advisable to work with a caliper to verify final tolerances.

Common Mistakes When Using Spacers

• Not checking total play before closing the chassis: it is important to ensure that the axle rotates freely without excessive lateral play once the spacers are in place.
• Mixing spacers of different thicknesses without measuring: small accumulated differences can misalign the crown gear relative to the pinion, causing noise or premature wear.
• Over-tightening the chassis screws: this can compress the spacers and block axle rotation.

Frequently Asked Questions

What scale are these spacers designed for?

They are specifically designed for 1/24 scale, with a 3 mm diameter axle, the standard commonly used in this scale within the Scaleauto range.

Can I combine multiple SC-8111C spacers for greater spacing?

Yes. With each measuring 1.5 mm thick, they can be stacked to achieve spacings of 3 mm, 4.5 mm, or other combinations, depending on the needs of each setup.

Why choose brass over other materials?

Brass offers good mechanical strength, stable dimensional tolerances, and does not rust, making it suitable for small precision parts subjected to continuous friction.

Are they valid for Sport track and Universal track?

The spacer itself is compatible with any car that uses 3 mm axles. The reference to the track (Sport or Universal) affects the car's guide, not the axle spacers.

Do I need any special tools to install them?

It is not essential, although working with a digital caliper makes verifying final tolerances easier and ensures a more precise result.
