0.10mm axle spacers 2.38mm

Precision to the Tenth: 2.38mm Axle Spacers from Sideways

In the preparation of a slot car, the details make the difference between a car that runs and one that wins. The SWSP01 axle spacers from Sideways, with a thickness of 0.10 mm and designed for 2.38 mm axles, are the ultimate tool for accurately controlling the lateral positioning of wheels, crown gears, and bearings on the rear axle.

Function and Performance

An axle spacer may seem like a minor part, but its impact on the car's behaviour is direct. By interposing one or more of these spacers between the elements of the rear end, the following can be controlled:

• The rear track width, which has a direct influence on cornering stability.
• The lateral play of the crown gear relative to the pinion, affecting transmission efficiency and noise level.
• The position of the bearings and their clearance within the bracket or chassis.

With a thickness of 0.10 mm, these spacers allow for very fine adjustments, stackable according to the needs of each setup. This is the type of adjustment that the most experienced preparers make before each competition session.

Compatibility

These spacers are designed for 2.38 mm diameter axles, a standard measurement in a wide variety of competitive slot cars. Before using them, check that your car's axle has exactly that diameter to ensure a clean fit without unwanted play.

Installation and Preparation

The installation is straightforward but requires attention:

1. Carefully disassemble the rear axle from the chassis, taking care not to damage the bearings or the crown gear.
2. Place the spacers in the desired position — between the wheel and bearing, between the bearing and bracket, or between the crown gear and pinion — according to the adjustment you seek.
3. Reassemble the axle and check that there is no excessive axial play or lateral rubbing.
4. Perform a short break-in run and assess whether it is necessary to add or remove any spacers.

Remember that stacking several 0.10 mm spacers allows for increments of 0.20 mm, 0.30 mm, and so on, providing great adjustment flexibility without the need for thicker pieces.

Common Mistakes

• Not verifying the axle diameter: using spacers of incorrect size can create play or prevent assembly.
• Overdoing the number of spacers: excessive track width can compromise the car's dynamic behaviour.
• Forgetting to rebalance the transmission: if you move the crown gear laterally, always check the engagement with the pinion.

Ideal for…

These spacers are aimed at enthusiasts and competitors who approach the preparation of their cars with rigor: those who leave nothing to chance and understand that every tenth of a millimetre can translate into more predictable and faster behaviour on the track.

Frequently Asked Questions

How many spacers are included in the SWSP01 pack?

The provided information does not specify the exact number of units per pack. We recommend checking the manufacturer's sheet or contacting us before placing your order if you need to confirm this information.

Are they compatible with any slot car?

They are designed for 2.38 mm diameter axles. Verify the measurement of your car's axle before using them; it is one of the most common measurements in the world of competitive slot racing, but not universal.

Can I combine several spacers to achieve greater thicknesses?

Yes. By stacking several 0.10 mm spacers, you can achieve increments of 0.20 mm, 0.30 mm, etc. This is a common practice in slot car preparation.

Does the spacer affect the transmission in addition to the track width?

It depends on where you place it. If you position it between the crown gear and the pinion, or shift the crown gear laterally, you should always recheck the transmission engagement to avoid efficiency losses or premature wear.

Does Sideways manufacture spacers for other axle diameters?

Sideways offers a range of spare parts and preparation accessories. To check the availability of spacers in other diameters, review the complete brand catalogue in our store.
