Steel Axles 3x20mm Alfa GTA 1/24

Original BRM spare part to keep the chassis of the Alfa GTA 1/24 in top condition

When an axle loses its straightness or accumulates wear, the model's behaviour on track is immediately affected: vibrations appear, cornering becomes unpredictable, and the bearings work harder than they should. The BRM S416A are the original replacement axles specifically designed to prevent this situation in the 1/24 scale Alfa GTA.

Function and performance

Manufactured from high-hardness steel, these 3 mm diameter and 20 mm length axles are ground to ensure a calibrated surface and absolute straightness. This directly translates into eccentricity-free rotation, clean power transmission from the crown gear to the wheels, and a uniform load on the bearings that extends the lifespan of the assembly.

• Diameter: 3 mm
• Length: 20 mm
• Material: high-hardness ground steel
• Original BRM reference: S416A

Compatibility

These axles are specifically designed for the BRM Alfa Romeo GTA in 1/24 scale. The 20 mm length corresponds to the track width of this model, making installation straightforward and ensuring that the wheel alignment is perfect. For any questions regarding compatibility with other versions in the BRM catalogue, we recommend checking the original reference of your model before placing your order.

Installation and preparation

Replacing axles is one of the most common maintenance operations in competitive slot racing and in the preparation of classics. When working with a calibrated axle like the S416A, the bearings fit without play, and the crown gear engages more precisely, reducing mechanical losses and improving acceleration response. Before installation, it is advisable to clean the axle housing and check the condition of the bearings to ensure that the assembly is in optimal condition.

Common mistakes

• Installing the axle without checking the condition of the bearings: a worn bearing can damage the new axle in just a few sessions.
• Forcing the axle during insertion: ground steel does not tolerate impacts; a firm and even support is sufficient for a proper fit.
• Confusing the length with other axles in the BRM catalogue: BRM offers several sizes; ensure that the reference S416A corresponds to your specific version of the Alfa GTA.

Is it necessary to lubricate the axle during installation?

In general, it is recommended to apply a minimal amount of specific slot lubricant at the contact points with the bearings, without overdoing it to avoid contaminating the track. Check BRM's recommendations for this specific assembly.

Can I use this axle in official competition?

As it is an original BRM replacement part, its use is suitable in categories that require homologated parts from the brand itself. Always check the regulations of the championship you are participating in.

How do I know if my original axle needs replacing?

The most common symptoms are vibrations at high speed, visible wear on the axle surface, play in the bearings, or irregular behaviour in corners that does not improve with other chassis adjustments.

The BRM S416A are precision ground steel axles, 3x20mm, engineered as original replacement parts for the BRM Alfa GTA slot car at 1/24 scale. Their calibrated surface ensures concentric rotation, low friction against bearings and consistent power transfer from crown to wheels — key factors for both club racing and collector-grade restoration.
