Maximize Power Tool & Automotive Gearing with RHEOLUBE 380 & 380-G1

Modern mechanical design demands efficient power transfer and durability. This is especially true with power tool and automotive gear systems. Whether it’s a compact consumer-grade angle grinder or a high-torque automotive gear assembly, gears are constantly exposed to high speeds, heavy loads, and extreme temperatures. Choosing the right lubricant can be the difference between long-lasting performance and early component failure.

Enter RHEOLUBE 380 and RHEOLUBE 380-G1, two advanced synthetic greases designed to meet the toughest mechanical challenges head-on.

Gear systems, particularly those in power tools and vehicles, rely on lubrication to:

• Reduce friction and wear between metal components
• Lower operating temperatures that can degrade materials and shorten service life
• Protect against corrosion, oxidation, and contaminants like dust and moisture
• Improve overall efficiency, starting torque, and operating smoothness

Traditional oil baths are not always feasible—especially in compact or mobile systems—so greases like RHEOLUBE 380 and 380-G1 offer a “lube-for-life” solution that eliminates the need for constant relubrication.

Both RHEOLUBE 380 and 380-G1 are PAO/Ester-based, lithium soap-thickened, and fortified with extreme pressure (EP) additives and rust inhibitors. These additives form a strong, non-corrosive protective layer that minimizes gear wear and prevents welding or galling under heavy loads.

Key Advantages

• Wide operating temperature range (-50 to 130°C), making them ideal for both low-temp starts and high-heat continuous operation
• Excellent metal-on-metal protection, even at elevated speeds and load conditions
• EP fortified for enhanced performance in high-pressure environments

Corrosion and oxidation resistance, even in harsh or humid environments

A leading power tool manufacturer needed a grease to handle the intense demands of angle grinders—tools used for abrasive applications and operate at high speeds of 6,500 to 8,500 rotations per minute. Angle grinders can generate a great amount of friction from regular use.

Results with RHEOLUBE 380 and 380-G1:

• Passed all life cycle test requirements
• Significantly reduced friction and heat generation in gearboxes
• Helped extend product life and reduce warranty costs
• Tailored application: RHEOLUBE 380 was ideal for smaller grinders, RHEOLUBE 380-G1, with its softer consistency (NLGI 1), worked better for larger models

Built for Automotive and Beyond

Automotive gearboxes experience frequent load shifts, extreme temperature fluctuations, and high torque—RHEOLUBE 380 series greases offer the durability, load resistance, and thermal stability that traditional greases struggle to deliver.

Whether used in electric motor gearboxes, drive shafts, or transmission components, these lubricants help maximize:

• Component longevity
• Efficiency under load
• Resistance to harsh environmental conditions

Engineered for Endurance. Ready for Your Gearbox.

RHEOLUBE 380 and 380-G1 are formulated for gear applications that demand performance, reliability, and endurance. From extending the lifespan of power tools to protecting critical automotive components, these greases deliver peerless results across a wide range of operating conditions.

If you're designing a gearbox for high-load or high-speed environments, or looking to upgrade your current lubrication strategy, RHEOLUBE 380 series should be your first choice solution.
