Mobil Almo 527
Mobil Almo 527 is a high-performance pneumatic tool lubricant developed for demanding mining, quarrying and industrial applications where pneumatically operated rock drills and air tools require dependable lubrication. Manufactured from high-quality base oils and advanced additives, Mobil Almo 527 delivers excellent chemical stability together with strong wear and corrosion protection. The formulation is designed to ensure reliable operation and extended equipment life in both underground and surface mining environments where pneumatic drilling equipment operates under severe mechanical and environmental conditions.
A key performance advantage of Mobil Almo 527 is its ability to maintain effective lubrication even in the presence of water. Compressed air used to power pneumatic tools often contains moisture that can contribute to corrosion and accelerated wear of internal components. Mobil Almo 527 is formulated with emulsifiable properties that allow the lubricant to absorb moisture carried in the air stream while still maintaining continuous oil films on metal surfaces. This capability helps minimise the negative effects of water on wear and corrosion while ensuring consistent lubrication of moving components.
Mobil Almo 527 also provides excellent anti-wear and load-carrying performance. Pneumatic rock drills and air tools experience repeated mechanical impacts and heavy loads during operation. The advanced additive technology used in Mobil Almo 527 helps protect pistons, valves and bearings from wear and damage, helping extend equipment life and maintain reliable tool performance over long service intervals. The lubricant’s high extreme-pressure capability also ensures adequate lubrication under severe operating conditions commonly encountered in mining and quarrying applications.
Another important benefit of Mobil Almo 527 is its strong adhesive properties. These characteristics allow the lubricant to cling effectively to metal surfaces, ensuring consistent lubrication even when tools operate in challenging environments. The oil maintains protective films on components while also resisting the formation of gummy deposits that could lead to sluggish valve operation in pneumatic equipment. This helps ensure reliable performance and smooth operation of air-powered drilling tools.
Mobil Almo 527 also features a high viscosity index and low pour point, allowing the lubricant to perform effectively across a wide range of operating temperatures. Pneumatic tools often experience rapid cooling due to compressed air expansion during operation, which can lead to icing or lubrication issues. Mobil Almo 527 maintains sufficient fluidity at low temperatures while still providing strong lubrication films at higher temperatures, ensuring consistent protection for drill components throughout the operating cycle. In addition, the lubricant produces very low levels of oil fog during use, helping reduce lubricant consumption and improving working conditions.
Mobil Almo 527 is recommended for use in pneumatically operated rock drills in underground and surface mining operations, as well as in pneumatic drills, jackhammers and other air-powered tools used in construction, quarrying and industrial applications. It is suitable for both percussion and rotary air-operated equipment where reliable lubrication and extended equipment life are required.
Physical characteristics include an ISO viscosity grade of 100, with a kinematic viscosity of approximately 100 mm²/s at 40°C and 11.5 mm²/s at 100°C. Mobil Almo 527 has a density of approximately 0.899 kg/l at 15.6°C, a flash point of approximately 220°C and a pour point of approximately −27°C, supporting reliable lubrication performance for pneumatic drilling equipment operating under demanding conditions.
