2 Double lip brass bearings

Precision in Every Turn: Double Lip Brass Bearings for Slot

Bearings are one of those elements that go unnoticed until they fail. An axle that does not rotate freely, a minimal play that turns into tenths lost per lap… In slot preparation, details make the difference. These double lip brass bearings (reference CXM183) are designed for those who leave nothing to chance.

Function and Performance

The double lip bearing offers a dual function: on one hand, it guides the axle precisely, reducing lateral play to a minimum; on the other, it acts as a seal, limiting the entry of dirt, dust, and abrasive particles that over time degrade the performance of the rear axle. The result is a cleaner, more consistent rotation with less energy loss due to friction.

The brass material is a classic choice in slot preparation due to its balance between hardness, machinability, and wear resistance. It withstands continuous operation well without overheating, and its fit in the chassis housing is usually precise and free of play.

Recommended Applications

This type of bearing is commonly used in:

• Replacement of factory original bearings to improve rear axle rotation.
• Slot car preparations aimed at club competition.
• Reconditioning of chassis with wear in the axle housings.
• Preparation projects where the aim is to minimize mechanical losses.

Installation and Preparation

For optimal installation, it is advisable to clean the chassis housing thoroughly before inserting the bearing. An excessively forced fit can deform the lip and compromise the sealing function. If the housing shows wear, it is recommended to check the internal measurement before proceeding.

It is recommended to apply a small amount of specific slot lubricant to the axle before installation, avoiding excess that could contaminate the crown gear or the interior of the bearing.

Common Mistakes

• Forcing the insertion: if the bearing does not enter smoothly, check measurements before applying pressure.
• Over-lubricating: excess grease attracts dust and particles that accelerate wear.
• Ignoring the mounting direction: the double lip has a functional orientation; mounting it backwards can reduce its effectiveness as a seal.

Frequently Asked Questions

How many units are included in this pack?

The pack includes 2 double lip brass bearings, reference CXM183.

What is the purpose of the double lip in a slot bearing?

The double lip acts as a seal, reducing the entry of dirt and particles into the interior of the bearing and prolonging the lifespan of the axle. Additionally, it improves the lateral guidance of the axle and minimizes play.

Is brass better than plastic or bronze in slot bearings?

Brass offers a good balance between wear resistance, dimensional accuracy, and thermal behaviour. It is a highly valued option in competition preparations for its reliability over time.

Do I need special tools to install these bearings?

In most cases, a small insertion tool or even a suitably sized screwdriver is sufficient to press them in carefully. Avoid direct blows that could damage the lip.

What lubricant should I use with them?

Always use a specific slot lubricant, in minimal quantity. Generic lubricants may be too thick or contain components that deteriorate the bearing materials over time.

The CXM183 pack includes 2 double-lip brass bearings for slot car axles, offering precise rotation, reduced lateral play, and effective dirt sealing. An essential upgrade for club racing preparation and slot car tuning, compatible with standard slot car chassis axle housings.
