Mobil Almo 525
Mobil Almo 525 is a high-performance pneumatic tool lubricant developed for demanding applications involving air-operated rock drills and pneumatic tools used in mining, quarrying and construction environments. Formulated using high-quality base oils combined with carefully selected additives, Mobil Almo 525 provides excellent chemical stability, reliable wear protection and strong resistance to corrosion. The lubricant is specifically designed to maintain effective lubrication even under harsh operating conditions commonly encountered in underground and surface mining operations.
One of the key advantages of Mobil Almo 525 is its ability to provide reliable lubrication in the presence of water. Pneumatic tools often operate with compressed air streams that may contain moisture. Mobil Almo 525 is formulated with emulsifiable properties that allow the oil to effectively pick up and manage moisture while maintaining continuous lubrication films on metal surfaces. This helps reduce the negative effects of water on wear and corrosion while ensuring consistent equipment performance.
Mobil Almo 525 also delivers excellent anti-wear protection and load-carrying capability. The advanced additive system helps protect critical tool components such as pistons, valves and bearings from wear under heavy-duty operating conditions. The lubricant’s strong extreme pressure characteristics support reliable performance of pneumatic tools subjected to severe mechanical loads, helping extend equipment life and reduce maintenance requirements.
Another important benefit of Mobil Almo 525 is its strong adhesive properties, which allow the lubricant to maintain a protective film on metal surfaces even under challenging operating conditions. These adhesive characteristics ensure that moving parts remain effectively lubricated, helping prevent metal-to-metal contact and protecting against corrosion. The oil also resists the formation of gummy deposits that could otherwise lead to sluggish valve operation in pneumatic equipment.
Mobil Almo 525 also features a high viscosity index and low pour point, enabling effective lubrication across a wide range of operating temperatures. Pneumatic tools can experience rapid cooling due to air expansion during operation. Mobil Almo 525 maintains adequate lubrication at low temperatures while still providing strong oil films at higher operating temperatures, ensuring consistent performance throughout the operating cycle. In addition, the oil produces very low levels of oil fog during use, improving working conditions and reducing lubricant losses.
Mobil Almo 525 is recommended for use in pneumatically operated rock drills used in underground and surface mining operations, as well as in pneumatic drills and jackhammers used in highway construction and building applications. It is also suitable for percussive and rotary air-operated tools used in quarrying and other industrial operations. The product is designed to deliver reliable lubrication performance throughout the year, even where seasonal temperature variations are significant.
Physical characteristics include an ISO viscosity grade of 46, with a kinematic viscosity of approximately 46 mm²/s at 40°C and 7.3 mm²/s at 100°C. Mobil Almo 525 has a density of approximately 0.883 kg/l at 15.6°C, a flash point of approximately 188°C and a pour point of approximately −30°C, supporting reliable lubrication performance for pneumatic drilling and tool applications operating under demanding conditions.
