Sideways AX45 Axles: Ground and Hardened Steel in 2.375 x 45 mm (3/32)

When track performance depends on every tenth, the rear axle cannot be a minor detail. The Sideways AX45 axles are made from ground and hardened steel, ensuring precise geometry, no vibrations, and the necessary stiffness to correctly transmit torque to the wheels.

Main Features

• Diameter: 2.375 mm (3/32)
• Length: 45 mm
• Material: ground and hardened steel
• Pack Contents: 2 units
• Manufacturer Reference: AX45

Function and Performance

The grinding process ensures that the axle maintains a uniform diameter along its entire length, eliminating small irregularities that can cause runout (eccentricity) and, consequently, vibrations that affect both the car's stability and the premature wear of bearings and tyres. The hardening, in turn, provides the necessary hardness to withstand the repeated mechanical stress of competition without deforming.

Assembly and Preparation

Before assembly, it is advisable to check that the chassis bearings are perfectly aligned with an axle aligner to avoid lateral stresses. Secure the crown and tyres with the appropriate adjustment elements and check the free rotation of the assembly before installing the motor. A well-mounted axle rolls without noticeable resistance and without any friction points when turned by hand.

Common Mistakes

• Forcing the axle if the bearings are not well aligned: this can cause bending and vibration.
• Not checking the eccentricity of the crown once mounted: even a perfect axle can be penalised by a poorly centred crown.
• Reusing a bent axle: hardened steel can withstand a lot, but if it has suffered a strong impact, it is best to replace it.

Frequently Asked Questions

How many axles are included in the pack?

The pack contains 2 units of the Sideways AX45 axle.

What does it mean that the axle is ground?

Grinding is a high-precision machining process that ensures a uniform diameter along the entire axle, minimising eccentricity and vibrations on track.

For which motorisation configurations is this axle suitable?

Being a standard rear axle of 3/32", it is compatible with sidewinder, inline, and anglewinder configurations, as long as the chassis accepts axles with a diameter of 2.375 mm and a length of 45 mm. Check your chassis specifications before assembly.

Can I combine this axle with bearings and crowns from other brands?

Yes, as long as the bearings have an inner diameter of 3/32" (2.375 mm) and the crown is designed for that same axle diameter. Check the compatibility of each component before assembly.

What should I do if the axle arrives with any surface irregularity?

A quality ground axle should not have visible irregularities. If you detect any defects, contact us before mounting it to manage the issue.
