3/32 axle spacers 0.12mm (10pcs)

Millimetre Precision for Your Slot Car Rear Axle

The NSR4810 spacers are designed for 3/32 (2.38 mm) diameter axles and offer a thickness of 0.12 mm per unit. Their function is as discreet as it is decisive: strategically placed along the rear axle, they allow for lateral adjustment of wheels, crown gears, and other components, eliminating unwanted play that translates into vibrations and loss of performance.

Function and Performance

When the rear axle has lateral play, power transmission becomes irregular and vibrations occur, penalising both top speed and corner stability. A spacer of just 0.12 mm can make the difference between an erratic car and one that runs cleanly and predictably on the track.

• Compatible axle diameter: 3/32 (2.38 mm)
• Thickness: 0.12 mm per unit
• Contents: 10 spacers per pack
• Main function: elimination of axial play and reduction of vibrations

Compatibility

The 3/32 axle is one of the most widely used standards in the world of competitive slot racing. These spacers are compatible with most chassis and kits that use this axle diameter, including NSR vehicles and accessories, as well as modifications on chassis from other brands that adhere to this standard. Always check your axle diameter before combining spacers of different thicknesses.

Installation and Preparation

Using spacers requires orderly and patient work. The usual practice is to add them one by one until the lateral play is eliminated without causing friction. A precision caliper or micrometer is very helpful for measuring the existing play before starting. Working on a clean bench with good lighting prevents losing these small parts during assembly.

• Place the axle in the axle holders and measure the lateral play before intervening.
• Insert the necessary spacers on each side until the play is nullified.
• Check that the axle rotates freely and without friction after adjustment.
• Having several units (as offered in this pack of 10) allows for flexible thickness combinations.

Common Mistakes

The most common mistake is over-tightening: by eliminating all play, if the axle holder screws are also tightened too much, the axle may become jammed. Another mistake is mixing spacers of different materials or origins without verifying that the actual thickness matches the nominal. Using a pack of 10 identical units from NSR avoids this problem.

Frequently Asked Questions

What exactly are axle spacers for?

They are used to fill the free space between the components mounted on the axle (wheels, crown gear, axle holders) and eliminate lateral play. Less play means less vibration and a more efficient power transmission.

Can I combine several spacers to achieve the thickness I need?

Yes. That is precisely why NSR offers them in packs of multiple units: you can stack two or more to reach the exact adjustment required for your setup.

Are they compatible with axles from other brands that also use the 3/32 standard?

In principle, yes, as long as the axle diameter is 3/32 (2.38 mm). However, check the tolerances of your axle holder before installation to ensure the piece fits correctly.

How many spacers do I need per car?

It depends on the play present in your setup. In typical preparations, between 1 and 3 units are usually used per side, although this varies depending on the chassis, crown gear, and type of wheels used.

Do they affect the total weight of the car?

The weight they add is practically negligible given their size, so you won't need to recalculate the car's balance after installing them.
