3mm Shaft Spacers in 0.5mm Photoetch Steel

Precision to the tenth: Scaleauto Photoedge axle spacers for 1/24 scale

In the preparation of a competition slot car, the smallest details make a difference. The 3mm Steel Axle Spacers with 0.5mm Photoedge from Scaleauto (ref. SC-8111E) are one of those components that may seem minor at first glance, but are crucial for the performance of the running gear and the proper transmission of power to the rear axle.

Function and performance

Axle spacers have a clear mission: to accurately position the various elements mounted on the axle —crown gears, tyres, bearings— and ensure that each piece operates in the precise location, without unnecessary play or unwanted friction. Poor lateral positioning can result in loss of traction, uneven wear, or erratic behaviour in corners.

Made from steel with a thickness of 0.5 mm and designed for 3 mm axles, these spacers from the Photoedge line meet the quality standard that Scaleauto applies across its range of competition spare parts for 1/24 scale. Steel as a material ensures superior durability compared to plastic equivalents and a resistance to deformation under load that is particularly relevant during extended running sessions.

Compatibility and installation

These spacers are designed for use with 3 mm axles, the most common standard diameter in Scaleauto's 1/24 scale. They are compatible with the usual rear axle configurations in competition chassis of this scale, whether in Sidewinder, Inline, or Anglewinder setups, as long as the axle used is 3 mm in diameter.

The installation is straightforward: they slide onto the axle in the desired position and act as a stop or spacer between components. For optimal adjustment, it is advisable to combine them with spacers of different thicknesses according to the specific needs of each setup.

Assembly and preparation

• Always ensure that the axle is clean and free of burrs before installing the spacers.
• Combine several spacers to precisely adjust the lateral position of crown gears and tyres.
• Check the freedom of rotation after installation: the axle should not experience additional resistance from excessive tightening.
• Visually inspect the centring of the tyres relative to the body before each running session.

Frequently asked questions

What axle diameter are these spacers designed for?

They are designed for 3 mm diameter axles, the most commonly used standard in 1/24 scale.

What is the thickness of each spacer?

Each spacer has a thickness of 0.5 mm, allowing for very fine adjustment of the axle components' position.

Are they compatible with other slot car manufacturers in 1/24 scale?

In principle, yes, as long as the rear axle of the car is 3 mm in diameter. However, we recommend checking the specifications of your model's axle before purchasing.

In what type of motor mounting can they be used?

They can be used in any 3 mm rear axle configuration: Sidewinder, Inline, or Anglewinder, as their function is independent of the type of motorisation.

How many units are included in the SC-8111E pack?

The provided information does not specify the number of units per pack. We recommend checking the exact contents on the product sheet or contacting us before placing an order.
