Traxxas TRX-5116 Ball Bearings: Blue Sealed for Precise and Durable Rolling

The Traxxas TRX-5116 ball bearings are original spare parts designed to maintain optimal performance of Traxxas models. With dimensions of 5x11x4mm and a blue rubber seal, they offer a combination of protection against external particles and smooth rolling, resulting in greater efficiency and reduced wear on drivetrain components.

Main Features

• Dimensions: 5x11x4mm, standard size in numerous Traxxas models.
• Blue rubber seal: protects the interior of the bearing from dust, dirt, and moisture, prolonging its lifespan.
• Pack of 2 units: allows for replenishing or upgrading the bearings on both sides of an axle in a single purchase.
• Original Traxxas reference: TRX-5116, ensuring fit and compatibility with models that specify this reference.

Function and Performance

A bearing in good condition reduces friction between the axle and the model's structure, directly translating into a more efficient transmission of the motor's power. When bearings are worn or contaminated, the model's response becomes erratic and the motor works harder. Replacing them with original units like the TRX-5116 restores the model's factory behaviour.

The blue rubber seal is particularly useful in intensive use sessions or in dirty environments, as it prevents particles from penetrating the balls and the inner raceway, which are the main causes of premature deterioration.

Installation and Preparation

The replacement process is straightforward: simply remove the worn bearings, clean the housing, and carefully press in the new ones until they seat properly. No additional lubrication is required as standard, although a minimal amount of specific bearing oil can further enhance smoothness under demanding conditions.

We recommend periodically checking the condition of the bearings, especially after sessions on abrasive surfaces or in the presence of water. Early detection of play or irregular noises allows for replacement before wear affects other drivetrain components.

Common Mistakes

• Forcing the bearing during installation without properly aligning the axle can damage the internal balls.
• Using inappropriate or excessive lubricants can deteriorate the rubber seal and attract dirt.
• Not verifying the exact reference before purchasing: ensure your model requires the size 5x11x4mm.

Frequently Asked Questions

Which Traxxas models are these bearings compatible with?

The reference TRX-5116 is indicated for Traxxas models that specify 5x11x4mm bearings. We recommend consulting the parts manual of your specific model or the official Traxxas website to confirm compatibility before placing an order.

How many units are included in the pack?

The TRX-5116 pack includes 2 units of blue rubber sealed ball bearings measuring 5x11x4mm.

What advantage does the rubber seal have over open bearings?

The rubber seal protects the interior of the bearing from dust, sand, and moisture, which prolongs its lifespan and maintains smoother rolling for longer, especially in off-road use or dirty environments.

Is it necessary to lubricate these bearings after installation?

The sealed bearings come with internal lubricant. For standard use, it is not essential to add more, although a small amount of bearing oil can improve smoothness under high-demand conditions.

Can I use these bearings in other models from other brands?

As they are a standard size (5x11x4mm), they may be physically compatible with other models that use this dimension, provided the housing and axle are equivalent. However, outside the Traxxas ecosystem, compatibility should be verified on a case-by-case basis.
