Titanium axle 2.35 x 55mm

Performance and durability in a single component: the titanium axle from Sloting Plus takes your slot car preparation to another level.

Titanium was already an exceptional material for slot axles: low density, high toughness, and outstanding stiffness that translates into clean and consistent transmission. Sloting Plus goes a step further with the SP042255 and applies an additional titanium coating of approximately 8 µm (8 microns), adding a layer of protection that significantly increases wear resistance at the contact points with bearings and brackets.

Why choose a titanium axle with coating

In competitive slot racing, every tenth counts. An axle that wears out or loses its original calibration introduces vibrations, misaligns the wheels, and penalises stability in corners. The titanium coating acts as a protective barrier over the titanium core itself, maintaining the original calibration for more race sessions and reducing friction at the supports.

Compared to conventional steel axles, this component offers less weight —something noticeable in the rotational inertia of the rear assembly— and greater corrosion resistance, making it particularly interesting for long-lasting setups or intensive club use.

Installation and preparation

The diameter of 2.38 mm (3/32'') is one of the most common sizes in competitive slot racing and is compatible with a wide variety of brackets, bearings, and wheels designed for this standard. Before installation, it is advisable to check the fit in the bearings: the axle should rotate freely but without lateral play. A correct installation starts with checking the alignment of the bracket and ends with a concentricity check of the wheels once installed.

Ideal for…

• Preparers looking to reduce unsprung weight in the rear end.
• Club competitors wanting a durable axle that maintains its calibration session after session.
• Enthusiasts who already know the advantages of titanium and want to upgrade to high-resistance coating.

Considerations

The 8-micron coating is very thin —it is what allows for maintaining the exact calibration of the axle— so it does not act as a filler for play. If the bearings or the bracket show wear, it is advisable to replace them before installing this axle to make the most of its performance. The indicated weight (1.06 g) refers to one unit.

Frequently asked questions

What is the difference between a normal titanium axle and one with a titanium coating?

The titanium core provides lightness and toughness, but the surface can wear at the support points. The titanium coating (≈8 µm) adds a layer of greater surface hardness, which reduces wear and prolongs the axle's lifespan without penalising weight.

What brackets and bearings is this axle compatible with?

With a diameter of 2.38 mm (3/32''), it is compatible with brackets and bearings designed for that standard, which is the most common in competitive slot racing. Always check the inner diameter of your bearings before installation.

How many units does the bag contain?

The bag contains 1 unit.

Is this axle suitable for both sidewinder and inline configurations?

Yes. The axle itself is compatible with both motor configurations; the choice of length (55 mm) and diameter must be adjusted to the requirements of the bracket used in each setup.

Does it require any special lubrication?

It is recommended to apply a minimal amount of specific slot lubricant at the support points with the bearings, just like with any other axle. The coating reduces friction but does not eliminate the need for periodic maintenance.

The Sloting Plus SP042255 is a 55 mm titanium axle with an additional titanium coating of approximately 8 microns, offering exceptional wear resistance alongside the inherent lightweight and toughness of titanium. Diameter 2.38 mm (3/32"), weight 1.06 g, sold as a single unit. A top choice for slot car racing enthusiasts and club competitors looking for precision-calibrated, long-lasting axles for sidewinder or inline motor setups.
