60mm x Hollow axle with titanium treatment 2.38

A hollow axle treated with titanium for those who leave nothing to chance in car preparation

The hollow titanium-treated axle from Sloting Plus (reference SP042160) is a precision piece designed for tuners and drivers looking to maximise the performance of their rear end. With a length of 60 mm and a diameter of 2.38 mm (equivalent to 3/32''), it is made from calibrated stainless steel and subjected to a titanium coating of approximately 8 microns (µm).

Function and performance

The titanium coating is not an aesthetic detail: it serves a specific technical function. By adding a layer of approximately 8 µm over the calibrated stainless steel, the axle gains wear resistance and tensile strength, two critical factors when the car operates at high revolutions or on circuits with demanding curves. The result is an axle that maintains its geometry better over time, contributing to a more stable transmission and a more predictable behaviour on track.

Its hollow construction reduces weight without sacrificing stiffness, a balance appreciated by the most meticulous tuners when adjusting the centre of gravity and mass distribution of the car.

Assembly and preparation

As a calibrated axle, its assembly is direct and precise: it fits with the appropriate clearance in axle holders and bearings compatible with the 3/32'' diameter. Before installation, it is advisable to ensure that the chassis supports are clean and free of burrs to make the most of the axle's machining precision. The titanium coating does not require any additional treatment prior to assembly.

It is common to use this type of axle in configurations where long-term durability is prioritised, especially in club championships with many heats accumulated or in test benches where the axle endures continuous cycles of load and traction.

Common mistakes

The most common mistake when working with precision axles is forcing the assembly if there is any misalignment in the chassis supports. A well-calibrated axle like this should slide smoothly; if it requires excessive pressure, the problem lies in the chassis or the bearings, not in the axle. Forcing it can generate vibrations and accelerate the wear of the supports, negating the advantages of the titanium coating.

Frequently asked questions

What advantage does the titanium coating provide over a standard stainless steel axle?

The titanium coating of approximately 8 microns increases surface resistance to wear and traction, which prolongs the axle's lifespan and maintains dimensional precision with continued use.

Is the hollow axle less resistant than a solid one?

Not necessarily. The hollow construction reduces weight, but when the base steel is stainless and calibrated, the structural stiffness remains more than sufficient for the loads that a slot axle endures under normal racing conditions.

What diameter of bearings and axle holders is this axle compatible with?

Measuring 2.38 mm in diameter (3/32''), it is compatible with bearings and axle holders designed for that standard, which is widely used in the slot racing world. Always check the tolerances from your chassis manufacturer before assembly.

Can the length of 60 mm be cut or adjusted?

Technically yes, with the appropriate tool for stainless steel. However, any cut in the coating area may locally affect the titanium layer at the cut point. If you need a different length, it is advisable to look for the axle in the specific measurement from the Sloting Plus catalogue.

Does the titanium coating require any special maintenance?

No. The titanium layer is durable and does not need additional treatments. Basic maintenance —cleaning and light lubrication of the supports— is sufficient to preserve the proper functioning of the axle.

The Sloting Plus SP042160 is a hollow stainless steel axle with titanium coating (approx. 8 µm), measuring 60 mm in length and 2.38 mm in diameter (3/32''). Designed for slot car competition preparation, it offers enhanced wear and traction resistance, precise calibration, and lightweight construction. Compatible with standard 3/32'' bearings and axle holders. A reliable upgrade for club racers and serious slot car builders looking for long-lasting performance parts.
