Slot.it Bronze Bushings: Precision on the Axle, Performance on the Track

Bronze bushings are one of those elements that go unnoticed until they fail. When the rear axle does not rotate smoothly, the car loses efficiency, friction increases, and performance drops significantly. The SIPA02 set from Slot.it offers two bronze bushings specifically designed for 2.38 mm axles with a length of 55 mm, fitting precisely into the mounts and chassis of the Slot.it range.

Function and Performance

Bronze is the classic and reference material for bushings in competitive slot racing. Its porous structure retains lubricant, resulting in minimal and sustained friction over many hours of running. Compared to other materials, bronze offers an excellent balance between durability, sliding, and cost, which is why Slot.it continues to include it in its technical catalogue.

• Material: sintered bronze, with lubricant retention capability.
• Inner diameter: 2.38 mm (Slot.it standard for rear axle).
• Length: 55 mm.
• Contents: 2 bushings per set.

Compatibility and Installation

These bushings are designed to fit into the mounts of Slot.it chassis that work with 2.38 mm axles. If you are preparing or tuning a chassis from the brand, we recommend always checking the dimensions of the housing before installation to ensure the fit is correct. A well-seated bushing should not move within the mount, but it should not require excessive force for insertion either.

To prolong their lifespan, apply a small amount of specific lubricant for bronze bushings before first use and after deep cleaning of the rear end.

Common Mistakes

• Not lubricating on first installation: sintered bronze retains lubricant, but it benefits from an initial application to activate that function.
• Forcing the fit: if the bushing does not enter easily, check that the mount housing is not deformed or dirty before pressing.
• Mixing measurements: ensure that the axle you are using is indeed 2.38 mm; a 3/32" axle (2.38 mm nominal) may have different tolerances depending on the manufacturer.

Frequently Asked Questions

Which Slot.it chassis are these bushings compatible with?

They are compatible with Slot.it chassis that use mounts for 2.38 mm axles. Check the technical sheet of your chassis to confirm the housing measurement before purchasing.

How many bushings does the SIPA02 set include?

The set includes 2 bronze bushings.

What advantage does bronze have over other materials for bushings?

Sintered bronze retains lubricant in its porous structure, which reduces friction consistently and prolongs the interval between maintenance. It is the reference material in competitive slot racing due to its balance between performance and durability.

What lubricant should I use with them?

Use specific lubricants for bronze bushings in slot racing, generally very light oils or spray lubricants designed for this type of application. Avoid thick greases that may accumulate dirt.

Can I use them on chassis from other brands?

As long as the mount housing accepts the dimensions of this bushing (outer diameter and length 55 mm), it is possible. The most important thing is that the fit is firm in the mount and that the 2.38 mm axle fits correctly.

The Slot.it SIPA02 bronze bushings are a reliable upgrade for any slot car enthusiast working with 2.38 mm axles. Designed for Slot.it chassis, these sintered bronze bearings ensure minimal friction, smooth axle rotation, and consistent performance on the track. A must-have spare part for club racers and serious hobbyists looking to maintain their cars in top condition.
