Bronze spherical bearings

Precision in Every Turn: Slot.it SICH14 Spherical Bronze Bearings

Bearings are one of those small details that make a real difference on the clock. An axle that rotates freely and without lateral play responds quicker, wears less, and transmits the motor's power more directly. These spherical bronze bearings from Slot.it, reference SICH14, are designed with that goal in mind: to provide axle support with minimal resistance and precise alignment under any usage conditions.

Product Features

• Inner diameter: 2.38 mm, compatible with standard competition slot car axles of that size.
• Material: sintered bronze, which combines low friction with significantly greater durability than plastic bushings.
• Spherical geometry: allows the bearing to self-align within the chassis housing, compensating for small deviations and reducing uneven axle wear.
• Pack of 6 units: sufficient quantity to equip several cars or have spare parts ready for the pit.
• Brand: Slot.it, reference SICH14.

Function and Performance

In a slot car, the rear axle directly transmits the motor's torque to the tyres. Any irregularity at the support points—whether due to a worn, misaligned, or overly loose bushing—results in vibration, energy consumption, and loss of traction. The spherical design of these bronze bearings absorbs those small imperfections in the assembly, ensuring that the axle rotates freely and centred.

Sintered bronze also has the advantage of retaining lubricant within its porous structure, which extends the lifespan of the assembly and reduces the need for frequent maintenance.

Compatibility and Installation

These bearings are designed for 2.38 mm axles, a very common size in the Slot.it catalogue and among other leading manufacturers in the segment. Before installing them, it is advisable to check the inner diameter of the housing in the chassis to ensure a proper fit. Installation is straightforward: they are inserted into the chassis housing, and the spherical design allows them to self-centre when tightening the assembly.

If you are working with chassis from other manufacturers, ensure that the housing diameter matches the outer geometry of the bearing before forcing the installation.

Common Mistakes

• Forcing the bearing into a housing of incorrect diameter: this can deform the part and negate the benefits of the spherical geometry.
• Installing without lubricant: although sintered bronze retains grease, a minimal amount of lubrication during installation improves initial running.
• Reusing visibly worn bearings: a bearing with excessive play introduces the same vibrations as a degraded plastic one.

Ideal for…

Slot car tuners looking to minimise friction on the rear axle, enthusiasts competing in club championships who want to make the most of every tenth, and anyone performing a complete assembly or overhaul of a Slot.it car or a chassis with a 2.38 mm axle.

Frequently Asked Questions

What is the benefit of having a spherical bearing instead of a cylindrical one?

The spherical geometry allows the bearing to self-align within the chassis housing. This compensates for small mounting deviations and prevents the axle from working at an angle, which would reduce its lifespan and increase friction.

Do I need to lubricate these bearings?

Sintered bronze retains lubricant in its structure, but it is recommended to apply a small amount of compatible grease when installing them to improve running from the first use.

Are they compatible with chassis from other brands besides Slot.it?

They are compatible with any chassis that uses bearing housings with matching outer diameter and 2.38 mm axles. Check the measurements of your chassis before installation.

How many units are included in the pack?

The pack contains 6 units, sufficient to equip several cars or have spare parts available.

How often should they be replaced?

It depends on usage and track conditions. In competition, it is advisable to inspect them periodically and replace them when excessive play or abnormal noise in the axle is noticed.
