NSR plastic transmission grease

Take Care of Your Transmission with NSR's Specific Grease for Plastics

Maintaining the transmission of a slot car in good condition is as important as choosing the right motor or tyres. The NSR Plastic Transmission Grease (ref. NSR4608) is specifically formulated to work with plastic materials — crowns, pinions, and gears — without attacking or degrading them, which is fundamental when discussing precision components.

Function and Performance

A poorly lubricated transmission generates unnecessary friction, noise, heat, and ultimately, premature wear of the crown and pinion teeth. This grease acts precisely where it is needed: it creates a protective film between the contact surfaces, reduces friction, and dampens the impacts of the transmission during acceleration and braking.

• Specifically formulated for plastic parts: it does not attack or swell the material.
• Reduces friction at the crown-pinion contact.
• Decreases wear and extends the lifespan of the components.
• Contributes to a quieter and more efficient transmission.

Compatibility and Applications

Especially indicated for plastic crowns and pinions, which are the most common in the vast majority of slot cars on the market. It is compatible with NSR transmission sets and those from other brands that use similar materials. It can be applied to both standard toothed crowns and finer competition ones.

Assembly and Preparation

The application is straightforward: simply deposit a small amount on the teeth of the crown or pinion before assembly, or directly on the already installed gear. A minimal amount is sufficient; excess can attract dirt and worsen performance. A good practice is to apply it during each car inspection or when a transmission change is made.

Frequently Asked Questions

Can I use this grease on metal crowns?

It is specifically designed for plastic transmissions. For metal crowns, there are other NSR lubricant references more suitable for that material.

How often should I lubricate the transmission?

It depends on usage. In intensive training sessions or competitions, it is advisable to check lubrication regularly. For recreational use, one application during each maintenance or part change is sufficient.

How much should be applied?

Very little: a few tenths of a millimetre on the teeth is enough to form the protective film. Excess does not improve lubrication and can attract dust and dirt into the car.

Is it compatible with cars from other brands besides NSR?

Yes, as long as the transmission parts are plastic. It is perfectly valid for plastic crowns and pinions from Slot.it, Scaleauto, Avant Slot, or any other brand that uses similar materials.

NSR plastic transmission grease (ref. NSR4608) is a precision lubricant designed for plastic gears, crowns, and pinions in slot cars. It reduces friction, prevents premature wear, and ensures smooth, efficient power delivery — an essential part of any slot car maintenance routine for club racers and hobbyists alike.
