0.75mm spacer set

Precision to the tenth: 0.75 mm axle spacers from Slot.it

When it comes to serious slot car preparation, adjusting the rear axle is one of those points where you can gain or lose without even noticing. The 0.75 mm axle spacers from Slot.it — reference SIPA52 — allow for precise control of the lateral play of the axle within the chassis, eliminating unnecessary movement that generates instability and affects power transmission to the track.

Function and performance

Axle spacers, also known as shims, are calibrated thickness pieces placed between the axle and the chassis supports. Their purpose is to reduce lateral play without generating friction: the balance between freedom of rotation and absence of parasitic movement. With a thickness of 0.75 mm, this set occupies a middle position in the Slot.it spacer range, ideal for fine adjustments when thinner spacers do not compensate for the existing play.

• Calibrated thickness of 0.75 mm for precise adjustment.
• Manufactured under Slot.it's tolerance standards.
• Compatible with Slot.it axles and chassis.
• Allow for the combination of different thicknesses to achieve the exact adjustment.

Installation and preparation

The installation process is straightforward but requires attention: remove the rear wheels, take out the axle from the chassis, and insert the spacers at the end or ends where there is play. It is advisable to check the lateral movement before and after installation to verify that the adjustment is correct. In competitive setups, many drivers work with a combination of spacers of different thicknesses to fine-tune without the need to machine any parts.

Compatibility

These spacers are designed for use with Slot.it axles and chassis, which operate on Sport track. Check the diameter of your axle before combining them with components from other brands.

Ideal for…

Preparers and drivers competing in club championships or in technical categories where the regulations require a controlled level of preparation. Also for enthusiasts who want to take a step further in tuning their cars without making irreversible modifications.

Frequently asked questions

What is the purpose of an axle spacer?

It serves to control the lateral play of the axle within the chassis. An axle with too much lateral play moves side to side during operation, causing instability in corners and loss of traction. The spacer occupies that excess space without preventing the free rotation of the axle.

How many spacers are included in the set?

The provided information does not specify the exact number of units included in the SIPA52 set. We recommend checking the official Slot.it datasheet or contacting us before placing your order if this information is relevant to your setup.

Can spacers of different thicknesses be combined?

Yes. It is a common practice in slot preparation: combining 0.5 mm and 0.75 mm spacers, for example, allows for adjustments that a single standard thickness would not cover.

Are these spacers compatible with chassis from other brands?

They are designed for the Slot.it system. Compatibility with chassis from other brands depends on the inner diameter of the spacer and the diameter of the axle used. Always check the measurements before combining components from different manufacturers.

Does using spacers affect torque or top speed?

Not directly. Their effect is on the stability and mechanical efficiency of the transmission. A well-adjusted axle can improve lap time consistency, but it does not modify the intrinsic characteristics of the motor.

Slot.it SIPA52 axle spacers 0.75mm — precision shims for slot car axle end-float adjustment, compatible with Slot.it Sport track system components. Essential for competitive preparation and club racing, these calibrated spacers help eliminate unwanted lateral play on the rear axle, improving consistency and stability through corners. A small but effective tuning upgrade for any serious slot car builder.
