0.10mm spacers for 2.38mm axle

Precision lateral adjustment with 0.10 mm spacers for 2.38 mm axle

When we talk about real tuning, the small details make the difference. These spacers from Scaleauto for 2.38 mm axles, made from photoetched steel and with a thickness of just 0.10 mm, allow for precise adjustment of the lateral play of the wheels and the position of crowns, pinions, or any element mounted on the rear axle.

Function and performance

The purpose of a spacer of this type is to eliminate unwanted play in the axle: that small lateral movement which, although imperceptible to the naked eye, directly affects the consistency of the drivetrain and the car's behaviour on track. With a thickness of 0.10 mm, these spacers allow for very fine corrections, stacking several units to achieve the optimal play without overdoing it.

• Material: photoetched steel
• Thickness: 0.10 mm
• Compatible axle diameter: 2.38 mm
• Includes adjustment tool for easy placement

Compatibility

The diameter of 2.38 mm is one of the most common standards in competitive slot racing. This size is compatible with a wide variety of setups, from rear axles of cars prepared for Sport track (Scaleauto, Slot.it) to custom installations with precision chassis and axles. Always check the exact diameter of your setup's axle before selecting the spacer.

Installation and preparation

The included adjustment tool significantly eases the task: placing spacers of just one-tenth of a millimetre without the proper tool can become a frustrating task. With it, the process is clean and precise. The usual recommendation is to measure the total lateral play with a digital caliper before deciding how many spacers to add, and to adjust progressively until achieving the minimum functional play without creating tension in the axle.

Common mistakes

• Stacking too many spacers without measuring the actual play: this can create tension and hinder the free rotation of the axle.
• Confusing the axle diameter: ensure that your axle is 2.38 mm and not 3/32" (nominally 2.38 mm) or 3 mm, which, although similar, are not interchangeable.
• Placing them without a tool: photoetched steel is delicate and can deform if forced with inappropriate tools.

Frequently asked questions

How many spacers does a typical setup usually need?

It depends on the existing lateral play. The usual practice is to start by measuring the play with a caliper and adding just the right amount of spacers to reduce it to the minimum functional level. In many setups, one or two units are sufficient, but it can vary depending on the chassis and type of mounting.

Can spacers of different thicknesses be combined?

Yes. Scaleauto offers spacers in different thicknesses (0.10 mm, 0.20 mm, etc.) that can be combined to achieve the exact desired adjustment. The key is always to measure first and adjust progressively.

Is the included tool necessary or can I do without it?

The adjustment tool greatly facilitates the installation and reduces the risk of deforming the parts. Since the thickness is only 0.10 mm, handling them by hand or with non-specific tools can be challenging and damage the spacer. We recommend using it at all times.

Are they valid for universal track axles (Scalextric, Ninco)?

As long as the axle diameter is 2.38 mm, yes. The spacer does not distinguish between track systems; what matters is the axle diameter. Verify the exact measurement before installing them.

Does photoetched steel withstand continuous use in competitive racing well?

Photoetched steel offers good resistance for this type of application. Being protected between the axle and adjacent elements, direct mechanical wear is minimal. Under normal club or competition use conditions, its durability is more than sufficient.
