PICK-UP GUIDE SPACERS .005" BRASS/0.12mm (10pcs)

Precision to the tenth of a millimetre: NSR brass spacers for pick-up guide

In the preparation of a slot car, the smallest details make the difference between a guide that works well and one that causes contact loss or erratic behaviour. These brass spacers from 0.12 mm (0.005") by NSR allow for precise adjustment of the vertical play of the pick-up guide, ensuring that the braids maintain a clean and constant contact with the rail.

Function and performance

The guide spacers act as precision shims between the guide and the chassis. Their function is to regulate the vertical clearance of the guide: too much play causes electrical contact loss and bouncing in transitions; too little results in excessive stiffness that transmits impacts to the chassis and penalises stability.

With a thickness of 0.12 mm per unit, these spacers allow for very fine and stackable adjustments, adapting to the tolerances of each chassis and guide. Brass, the material chosen by NSR, offers good rigidity, resistance to deformation, and stable behaviour against temperature changes that occur during intensive running sessions.

Compatibility and application

Designed for use with NSR pick-up guides, although their standard format makes them compatible with other guides of similar geometry. If you have doubts about compatibility with your specific model, we recommend checking the dimensions of the guide before installation.

• Material: brass
• Thickness: 0.12 mm (0.005")
• Contents: 10 units per pack
• Brand: NSR
• Reference: NSR4818

Installation and preparation

The installation process is straightforward but requires attention: they are placed between the guide and its housing in the chassis, stacking the necessary units until the desired play is achieved. It is common to start with one or two spacers and check the behaviour on track before adding more. A practical rule: the guide should be able to move vertically freely but without pronounced bobbing.

For coarser adjustments, NSR offers spacers in other thicknesses that can be combined with these 0.12 mm to achieve the exact measurement needed for each setup.

Common mistakes

• Stacking too many spacers: if the guide is too high, the braids lose pressure on the rail and current cuts occur.
• Not cleaning the housing before installation: dirt or lubricant residues can alter the actual play even if you have stacked the correct pieces.
• Ignoring adjustment after an impact: after a strong collision, it is advisable to check if the spacers have suffered deformation or displacement.

Ideal for…

Preparers who work on fine-tuning their cars for club or championship competition, and also for enthusiasts who want to optimise the performance of their models on universal or sport track. A pack of 10 units allows for the preparation of several cars or experimenting with different configurations without running out of material.

Frequently asked questions

How many spacers are usually used per car?

It depends on the chassis and guide, but it is common to use between one and three spacers of 0.12 mm to achieve the correct play. The best approach is to adjust on track, testing from less to more.

Can they be combined with spacers of other thicknesses from NSR?

Yes. NSR manufactures spacers in different thicknesses specifically to be combined and achieve intermediate measurements with total precision.

Are they reusable?

Under normal conditions, yes. Brass is sturdy enough to withstand multiple installations and removals without deforming, as long as they have not suffered direct impacts.

Do they work with guides from other brands?

It depends on the geometry of the guide housing. In many cases, they are compatible with third-party guides, but it is advisable to verify the dimensions before installation.

Do they affect the electrical contact of the braids?

Indirectly, yes. Correct spacing ensures that the braids maintain the appropriate pressure on the rail, resulting in cleaner and more stable electrical contact.
