Titanium axle 2.35 x 57mm

The axle that takes titanium properties a step further, with coating included.

Sloting Plus has worked extensively with titanium to create an axle that not only utilises the natural virtues of the material but enhances them. The result is the SP042257: precision-ground titanium, accurately calibrated and coated with an additional layer of titanium of approximately 8 microns (8 μm) that multiplies its wear resistance without compromising an ounce of lightness.

Function and performance

In the preparation of a competition slot car, the rear axle is one of the elements that most influences power transmission and the dynamic stability of the assembly. An axle with play, misalignment, or wear causes vibrations, traction loss, and unpredictable behaviour in corners.

Titanium, due to its intrinsic properties, offers an exceptional strength-to-weight ratio: it is significantly lighter than steel and, at the same time, very tough. This translates into an axle that rotates with less rotational inertia, favouring motor response and reducing mechanical losses.

The additional titanium coating — that 8-micron layer that Sloting Plus applies over the base material — is what sets this axle apart from conventional titanium axles. The hardened surface withstands continuous friction with supports and bearings much better, extending the component's lifespan even under intensive use in clubs or during prolonged tuning sessions.

Assembly and preparation

As a factory-ground and calibrated axle, it arrives ready to mount directly, without the need for prior adjustments. Nevertheless, as with any precision axle, it is advisable to check the alignment with the chassis and ensure that the supports and bearings are in good condition to avoid compromising the grinding work.

The diameter of 2.38 mm (3/32'') is a widely accepted standard in the world of competition slot racing, compatible with a wide variety of crown gears, pinions, and transmission parts designed for this size. Always check your chassis specifications before making the final assembly.

Ideal for…

• Preparers and club drivers looking to reduce weight without sacrificing durability.
• Competition setups where axle precision is critical for the overall performance of the car.
• Replacement of worn or loose axles in high-performance chassis.
• Discerning hobbyists who want to install the best available in the aftermarket.

Points to consider

The contents of the bag is 1 unit. If your project requires renewing the axle and you have doubts about the necessary length or diameter, always measure the original axle before ordering to ensure that the reference fits your application.

Frequently asked questions

What real advantage does the titanium coating provide over an uncoated titanium axle?

The coating of approximately 8 microns hardens the outer surface of the axle, significantly increasing its wear resistance due to friction. This is especially relevant at the contact points with the supports and bearings, which are the most punishing on the material during continuous use.

Which chassis systems is this axle compatible with?

The diameter of 2.38 mm (3/32'') is a very common standard in competition slot racing. However, compatibility depends on the specific design of each chassis and its bearings. Always check the specifications from your chassis manufacturer before mounting.

Does it require any special lubrication?

It does not require special lubricants beyond those you already use regularly on your supports and bearings. The titanium coating improves wear resistance, but proper lubrication at the contact points always helps to prolong the life of all transmission components.

How many units does the bag include?

The bag includes 1 unit.

Does factory grinding guarantee that the axle arrives perfectly centred?

Yes, grinding and calibrating ensure precise geometry from the outset. Nevertheless, it is always advisable to verify the complete assembly in the chassis to rule out tensions or misalignments introduced by other components.

The Sloting Plus SP042257 is a precision-ground, calibrated titanium axle with an 8-micron titanium coating, measuring 57 mm in length and 2.38 mm (3/32'') in diameter, weighing just 1.06 g. Designed for slot car competition, it delivers an outstanding strength-to-weight ratio combined with exceptional surface hardness and wear resistance — a top choice for club racers and serious hobbyists looking to maximise drivetrain performance.
