2.375 x 48mm (3/32)

Sideways AX48 Axle: Ground and Hardened Steel in 3/32 size of 48 mm

In the preparation of a competitive slot car, the rear axle is one of the elements that most influences track behaviour. A poorly ground axle introduces vibrations, penalises power transmission, and makes precise adjustment of crowns and bearings impossible. The Sideways AX series axles are made from ground and hardened steel to ensure concentricity and hardness from the outset.

Main Features

• Diameter: 2.375 mm (3/32)
• Length: 48 mm
• Material: ground and hardened steel
• Pack Contents: 2 units
• Reference: SWAX48 (Sideways AX48)

Function and Performance

The grinding ensures a uniform geometry along the entire length of the axle, resulting in a clean and eccentricity-free rotation. The hardening of the steel provides the necessary strength to withstand torsional stresses in high-power setups, preventing premature deformations that could affect torque distribution between wheels.

The 3/32 size (2.375 mm) is one of the most widespread in the competitive slot world, compatible with a wide variety of crowns, pinions, and bearings of that inner diameter. The length of 48 mm offers sufficient travel for most 1/32 scale chassis with inline, sidewinder, or anglewinder configurations.

Assembly and Preparation

Before mounting the axle, it is advisable to check that the bearings and chassis supports are well aligned. A slight misalignment causes premature wear on both the axle and the bearings. Apply a minimal amount of specific axle lubricant at the contact points with the bearings, ensuring that the lubricant does not reach the crown or pinion.

If you use axle adhesive to secure crowns or spacers, ensure that the axle is perfectly clean and dry in the application area. Excess adhesive can hinder future replacements.

Common Mistakes

• Forcing the axle during assembly if there is resistance: the correct approach is to check the alignment of the supports.
• Using axles of incorrect diameter with bearings of another size: this causes play or blockages.
• Ignoring the surface finish of the axle: scratches or dents can create imbalances at high speed.

Frequently Asked Questions

What does it mean for the axle to be ground and hardened?

Ground means that the axle has undergone a precision machining process that ensures a uniform diameter and a smooth surface along its entire length. Hardened indicates that the steel has received a heat treatment that increases its hardness and resistance to deformation under stress.

What type of crowns and bearings is this axle compatible with?

It is compatible with crowns, pinions, and bearings of inner diameter 3/32 (2.375 mm). Always check the inner measurement of the component before mounting.

For which motor configurations is this axle suitable?

The length of 48 mm and diameter 3/32 make it suitable for inline, sidewinder, and anglewinder setups in 1/32 scale chassis, depending on the width of the chassis and the position of the motor. Verify the measurements of your chassis before choosing the axle length.

Does the pack always include 2 units?

Yes, the reference SWAX48 includes 2 axles with the same characteristics.

Do I need special tools to mount this axle?

It is not essential, but having an axle puller and an alignment tool greatly facilitates assembly and reduces the risk of damaging the axle or bearings during the process.
