MOBIL ALMO 527

MOBIL ALMO 527 is a premium quality high-performance product primarily intended for the lubrication of pneumatically operated rock drills in underground and surface mining operations. The MOBIL ALMO 525 oils are formulated from high-quality base stocks and additives, which provide excellent chemical stability and good protection against wear and corrosion. They offer an optimum balance of adhesiveness, yet are emulsifiable enough to pick up moisture carried in the air stream reducing the negative effects of water on wear and corrosion. They do not form gummy deposits that could cause sluggish valve action. Even in the presence of water, the MOBIL ALMO 527 oils have good preferential metal-wetting properties that maintain continuous oil films.

Product Application

MOBIL ALMO 527 oils are recommended for use in all pneumatically operated rock drills in both underground and surface mining as well as in contractor and other industrial applications. They are suitable for percussive- and rotary- type tools. The viscosity grades allow selection for year- round use where seasonal ambient temperature variations are extreme.

  • Pneumatically operated rock drills in underground and surface mining operations
  • Pneumatically operated drills and jack hammers in highway construction and building operation
  • Rock drills in quarry operations
  • Percussion and rotary air-operated tools in industrial applications
