50 mm Steel Axle for Slot: Precision in Every Tenth

When preparing a slot car with rigor, even the most modest mechanical components make a difference. This rear axle of 50 mm and 2.38 mm diameter, made from high-quality steel, is one of those elements that should not be overlooked. It is supplied in a pack of 2 units (ref. CXM054).

Technical Features

• Length: 50 mm
• Diameter: 2.38 mm
• Material: high-quality steel
• Contents: 2 axles per pack
• Reference: CXM054

Function and Performance

The rear axle is the element on which the drive wheels rotate and to which the crown gear and tyres are attached. A straight, well-dimensioned axle made from stable material is essential to ensure a clean transmission, free from vibrations and power loss between the motor and the track. The high-quality steel used in this component provides rigidity and wear resistance, two essential qualities during intense running sessions or in club racing contexts.

Compatibility and Installation

The 2.38 mm measurement is one of the most widespread standards in the slot world, compatible with a wide variety of chassis, crown gears, and wheel hubs designed for this diameter. Before installation, it is advisable to check that the axle supports (bearings) of the chassis accept this diameter and that the 50 mm length fits the car's track width. A good fit in the supports, without lateral play or excessive friction, is key to getting the most out of the axle.

Preparation and Common Mistakes

When mounting the axle, it is advisable to check its straightness by rolling it on a flat surface before installation: any minimal deviation is amplified on the track and generates vibration. Avoid overtightening the support screws if using bearings with a fixing screw, as this could create a friction point that hinders the free rotation of the axle. The pack includes 2 units, allowing you to always have a spare on hand or prepare two chassis in parallel.

Frequently Asked Questions

What diameter does this axle have?

The diameter is 2.38 mm, one of the most common standards in slot spare parts for crown gears, wheel hubs, and bearings.

How many axles does the pack include?

The CXM054 pack includes 2 axles of 50 mm.

How do I know if this axle is compatible with my chassis?

You should check that the bearings of your chassis accept a diameter of 2.38 mm and that the 50 mm length corresponds to the track width of your car. Consult the specifications from the chassis manufacturer or measure the original axle before making the change.

Do I need special tools to mount it?

In most cases, standard slot preparation tools are sufficient: wheel puller, Allen key for the bearing screws, and a flat surface to check the axle's straightness. No special tooling is required.

Does the length of the axle affect track performance?

Yes. An axle that is shorter or longer than recommended for the chassis can cause the wheels to be misaligned, affecting grip and stability in corners. Always check that the length is appropriate for your setup.

The CXM054 is a 50 mm steel axle (2.38 mm diameter) for slot cars, supplied in a pack of 2 units. A precise and durable replacement part for slot car preparation, compatible with the most common 2.38 mm standard axle supports and hubs. Essential for club racing setups and serious hobbyists looking for reliable drivetrain components.
