3mm axle spacers in 1mm brass.

Millimetre Precision for Axle Positioning in 1/24 Scale

When tuning makes the difference between a well-balanced car and one that loses time in every corner, the smallest details are what matter. The 3 mm Brass Axle Spacers with 1 mm Thickness (SC-8111D) from Scaleauto are designed precisely for that: to allow you to accurately control the lateral play of the rear axle and the positioning of wheels, crown gears, and bearings within the powertrain assembly.

Function and Performance

An axle spacer serves a seemingly simple but highly impactful function on the car's behaviour: it occupies the excess space between the components mounted on the axle and the chassis or bracket walls, eliminating unwanted play. An axle with too much lateral play generates vibrations, uneven wear, and loss of traction, especially during direction changes.

• Compatible Axle Diameter: 3 mm.
• Spacer Thickness: 1 mm.
• Material: brass, which combines rigidity, wear resistance, and low friction compared to steel axles.
• Application Scale: 1/24.

Compatibility and Installation

This spacer is aimed at installations in 1/24 scale with 3 mm diameter axles, the most common measurement in this scale for both plastic and machined aluminium chassis. It is compatible with inline, sidewinder, and anglewinder configurations, as it acts directly on the axle and does not depend on the motor orientation.

The brass facilitates repeated assembly and disassembly without damaging the axle, which is appreciated during tuning sessions where different configurations are tested before a race.

Installation and Preparation

The installation process is straightforward: the spacer is placed on the axle in the desired position before fitting the corresponding wheel, crown gear, or bearing. For optimal results, it is advisable to plan the order of the components on the axle before starting the assembly, especially if combining several spacers of different thicknesses to adjust the lateral position with millimetre precision.

Scaleauto, with extensive experience in the spare parts and tuning segment for slot racing on Sport track, designs these parts to fit without forcing and without leaving play, facilitating a clean and repeatable assembly.

Common Mistakes

• Mixing spacers of different materials (plastic and brass) on the same axle can create compression differences and imbalances; it is preferable to use the same material at all points on the axle.
• Over-tightening adjacent components to the spacer can block the free rotation of the axle; always check that the axle rotates freely after assembly.
• Not checking the lateral play before and after assembly is one of the most common mistakes in preparation: a couple of quick measurements with calipers save a lot of time on the track.

Frequently Asked Questions

What scale is this spacer designed for?

It is designed for 1/24 scale, which is the reference scale indicated by Scaleauto for this reference SC-8111D.

What axle diameter is it compatible with?

The spacer is compatible with 3 mm diameter axles, the most widespread standard measurement in 1/24 scale.

Why brass and not steel or plastic?

Brass offers an interesting combination for this application: it is rigid enough not to deform under load, but softer than steel, which reduces wear on both contact surfaces. Additionally, its weight is moderate and does not add unnecessary mass to the assembly.

How many spacers are included in the package?

The information provided by the manufacturer does not specify the exact quantity per sales unit. We recommend checking the product sheet in-store or contacting our team to confirm before placing your order.

Can I combine it with spacers of different thicknesses from Scaleauto?

Yes. Scaleauto offers spacers in various thicknesses for 3 mm axles, allowing for precise lateral positioning by combining several pieces according to the assembly needs.

Is it valid for Sport track and Universal track?

The spacer acts on the car's axle and has no direct relation to the type of track. It is equally valid regardless of whether your circuit uses Sport track (Scaleauto, Slot.it) or Universal track (Scalextric, Ninco).
