To meet these needs, Mascherpa offers specific and high-performance solutions.
In this context, the MOLYKOTE® G-5133M Wide Temperature Range Grease is an innovative grease developed for dynamic applications over a wide temperature range. Its formulation, free of hazard labeling and optimized for the new generation of automotive and electrical systems, provides a concrete response to the needs of modern industry.
The New Lubrication Needs in the Automotive Sector
With the transition from traditional internal combustion engines to electric motors, the requirements for lubricants also change. While the challenge in the past was to reduce friction and consumption, today the focus is on ensuring energy efficiency, resistance to critical environmental conditions, and long-term reliability.
Components such as bearings of electric actuators, transmission systems, or cooling units must operate under variable conditions: low starting temperatures, thermal peaks during operation, exposure to water or chemicals. Without adequate grease, there is a risk of performance drop or premature failure.
Features of MOLYKOTE® G-5133M
MOLYKOTE® G-5133M stands out for a unique combination of properties that make it ideal for the automotive world and the transition to e-mobility:
- Wide temperature range (-73°C to +220°C)
Ensures consistent lubrication in both extreme cold and high-temperature environments. - Oxidative and mechanical stress stability
Prevents lubricant degradation, extending component life. - Reduced oil bleed, evaporation, and volatilization (<3%)
Essential in applications requiring low vapor emission or reduced condensation risk. - Compatibility with elastomers, polymers, and metals
Allows cross-use on multiple types of components. - PFAS-free formulation
An advantage also in terms of sustainability and compliance with the latest regulations.
Typical Applications
MOLYKOTE® G-5133M is used in a wide range of automotive and industrial applications, including:
- Bearings for actuators and electric motors
- Refrigeration and freezing components
- Exhaust fans and ovens
- Guides, valves, control cables, and transport systems
This versatility makes it a strategic choice for those looking to consolidate the use of multiple greases into a single solution, reducing complexity and management costs.
Tested performance of MOLYKOTE® G-5133M
The grease was developed using the advanced testing capabilities of MOLYKOTE® laboratories, with particular attention to electrification requirements. The results of key standardized tests show:
- Reduced oil bleed: up to three times lower than competing products (ASTM D6184).
- Long-term stability: no variation after 100 hours at 99°C (ASTM D942).
- Corrosion resistance: 1b rating on copper and 0 score on EMCOR test.
- Shear stability: less than 5% variation after 100,000 cycles, compared to 25% for traditional greases.
- Water washout resistance: excellent performance (ASTM D1264).
- Low-temperature performance: reduced torque down to -73°C, comparable to MOLYKOTE® 33M Extreme Low Temperature.
Lubricants for E-Mobility
In the context of electric mobility, lubricants for electric vehicles must not only reduce friction and wear but also ensure:
- Efficiency in low-energy consumption systems.
- Compatibility with advanced materials (polymers, elastomers, light alloys).
- Resistance to extreme conditions, typical of batteries and cooling systems.
For this reason, it is essential to select the lubricant suitable for the specific requirement. MOLYKOTE® G-5133M meets these needs with a formulation that optimizes bearing greases and other critical applications in electric vehicles.
Conclusion
The evolution of the automotive and e-mobility sectors requires advanced lubrication solutions capable of ensuring high and lasting performance under variable conditions. The MOLYKOTE® G-5133M Wide Temperature Range Grease provides a concrete response to these challenges: a reliable, versatile grease designed to support the technological innovation of vehicles and electric machines.
