Molybdenum Grease

Real protection for your gears: Tamiya Molybdenum Grease, a benchmark in modelling and mechanical preparation

When gears operate under load or continuously, lubrication makes the difference between a mechanism that lasts and one that wears out prematurely. The Tamiya Molybdenum Grease (TA87022) is one of the most valued options among modelling and RC vehicle enthusiasts precisely for that reason: it delivers on its promises without complications.

Main features

• Format: 10g jar, manageable and with a long shelf life as it is used in small quantities.
• Composition: grease with molybdenum disulfide (MoS₂) additive, a compound that acts as a solid lubricant and creates a protective film on metal surfaces.
• Stable viscosity: maintains its lubricating properties over a wide temperature range, without becoming excessively liquid or hardening too much.
• Friction reduction: molybdenum particles penetrate the micro-irregularities of surfaces, decreasing friction and wear.
• Uniform coverage: effectively covers the entire contact surface, which is especially important in gear trains with multiple friction points.

Recommended applications

This grease is primarily indicated for gears and moving parts in mechanical operations. In the field of modelling and RC vehicles, it is particularly useful in:

• Gear trains of RC vehicles (differentials, gearboxes, axles).
• Mechanisms of models with articulated or moving parts.
• Any metal-metal or plastic-metal contact point where a durable and stable lubricant is required.

Behaviour and performance

Molybdenum disulfide is a solid lubricant with a long history in high-demand industrial applications. In modelling, its main advantage is that it does not easily migrate outside the application area —unlike fine oils— and forms a protective layer that lasts beyond simple surface lubrication. This makes it particularly interesting in areas where we do not want to re-contaminate the assembly with excess lubricant or where access for reapplication is difficult.

Usage recommendations

• Apply a small amount directly onto the gear teeth or contact area. A little is sufficient.
• Spread with a toothpick or fine applicator to ensure uniform coverage.
• Avoid applying it to surfaces that will be in contact with soft rubber or silicone without first checking compatibility.
• Store the jar with the cap tightly closed to preserve its properties.

Frequently asked questions

What type of gears is this grease most suitable for?

It is suitable for both plastic and metal gears, in static models with articulated parts as well as in RC vehicles. Molybdenum is especially useful when there is metal-metal friction, as it creates a wear-resistant protective film.

How much should be applied?

Very little. A small, well-distributed amount is sufficient to cover the teeth of a complete gear train. Excess does not improve lubrication and may attract dirt.

Is it compatible with plastics?

Tamiya Molybdenum Grease is formulated for use in modelling and RC, so it is compatible with the plastics commonly used in these products. If in doubt with a specific plastic, it is advisable to test in a less visible area before applying it to the entire assembly.

How often should it be reapplied?

It depends on usage and working conditions. One of the advantages of molybdenum is precisely its durability: it does not evaporate like a fine oil and the protective layer tends to last longer. In regular use in RC or modelling, it is usually not necessary to reapply frequently.

Is it suitable for lubricating parts other than gears?

Yes, it can be used on any moving part that requires a thick and durable lubricant: sliding guides, pins, metal joints, and similar. However, it is not indicated for high-speed parts that require a low-viscosity oil.

Tamiya Molybdenum Grease (TA87022) is a reliable lubricant for gears and moving parts in RC vehicles and scale models. Its molybdenum disulfide formula provides a lasting protective film, reduces friction, and maintains viscosity across a wide temperature range. Ideal for plastic and metal gears, differentials, and mechanical assemblies in modelling and RC hobbies. 10g jar.
