H 3mm Aluminium Purple Retaining Sleeve with Head

Precision in Aluminium: the H 3mm Purple Retaining Sleeve from Scaleauto

The H 3mm retaining sleeve SC-8170B from Scaleauto is one of those small parts that make a difference on the workbench. Made from anodised aluminium in purple, it combines lightness, strength, and immediate visual identification that facilitates the organisation of your workshop.

Function and Performance

Headed retaining sleeves serve a critical function in the mechanical assembly of a slot car: they ensure the correct positioning of axles, bearings, and other components, preventing unwanted lateral movement during operation. The headed design provides a reference stop that simplifies assembly and ensures a more controlled fixation.

Compatibility and Installation

This sleeve is designed for 3 mm axles, a common measurement in many slot racing and preparation setups. Its anodised aluminium finish not only reduces weight compared to steel versions but also protects the part against corrosion and wear from continuous friction.

The purple anodised colour is not merely aesthetic: it allows for quick differentiation of this sleeve from others with different diameters or references when working with multiple sizes on the bench, reducing assembly errors.

Preparation and Tuning

In the preparation of a slot car, the correct securing of the axles directly affects power transmission, cornering behaviour, and the overall stability of the vehicle. A well-chosen and correctly installed sleeve eliminates lateral play of the axle, improves response in chicanes, and reduces vibration at high speeds.

We recommend checking the sleeve adjustment after a certain number of sessions, especially in setups subjected to high lateral loads or on tracks with demanding curve profiles.

Frequently Asked Questions

What type of axle is this sleeve designed for?

It is designed for 3 mm diameter axles, one of the most common sizes in the construction and preparation of competitive slot cars.

What advantage does anodised aluminium offer over other materials?

Anodised aluminium is lighter than steel and has an oxide layer that protects it from wear and corrosion, extending the lifespan of the part without adding unnecessary weight to the assembly.

Does the purple colour have any technical function?

Yes. The coloured anodising allows for quick visual identification of the diameter or reference of the sleeve, which is very useful when working with multiple sizes simultaneously on the preparation bench.

What does "headed" mean in this type of sleeve?

It means that the part incorporates a flange or stop at one end, which facilitates its positioning during assembly and provides a physical reference to control the insertion depth into the axle.

Is it compatible with Sport track and Universal track systems?

Compatibility depends on the chassis and mechanics of the car, not the type of track. This sleeve is an internal preparation component of the vehicle, so its use is not limited by the track system.

The Scaleauto SC-8170B is a 3mm aluminium axle spacer with head, anodised in purple for easy visual identification on the workbench. Lightweight and precise, it is an essential slot car preparation component for ensuring correct axle positioning and eliminating lateral play. Compatible with 3mm axles widely used in slot racing and competition builds. Available at Ministry of Hobby, your specialist slot car and scale modelling store.
