Spray Grease for Open Gears


Castrol Tribol™OG 500-0 (previously called Castrol Tribol™ 5000) with TGOA is a high-performance open gear grease.
It was especially developed for application in cement, mining and other heavy industries, to assure proper tribo-technical
and economical maintenance of open gears through automatic spray systems.
Castrol Tribol™ OG 500-0 differs from conventional asphaltic type open gear lubricants, as it does not contain solvents
nor solids.
It has outstanding extreme pressure (EP) antiwear characteristics derived from the latest development in the field of
surface improving additives designated TGOA.
The TGOA additive package performs better than other EP and antiwear additives because of its unique action on
frictional surfaces.
Castrol Tribol™ OG 500-0 is approved by major original equipment manufacturers.

  • Castrol Tribol™ OG 500-0 is manufactured from mineral oil, selected for optimum physical and chemical
    stability, blended with special adhesive agents and thickened with aluminum-complex soap.
  • The TGOA additive package is activated by high specific loads and corresponding temperatures causing a
    chemical-physical reaction. This results in an equalization of surface roughness without creating abrasion.
  • Therefore, surface roughness is reduced without the loss of surface material.
  • The results of the TGOA additives can be compared with a rolling process in the micro-range. The surface
    roughness is gradually leveled and smoothed.
  • The load carrying area is increased with increased safety loads on tooth flanks at reduced friction levels.
  • If, because of shock loads or stop-and-go operation, surface roughness peaks redevelop, the TGOA additive
    package is automatically reactivated. Surface roughness is again equalized and lubrication optimized.
  • Castrol Tribol™ OG 500-0 is a high-performance lubricant for open gears, wire ropes and similar applications.
  • Castrol Tribol™ OG 500-0 was developed for application through automatic spray systems, but may also be
    applied manually. Heat or the addition of thinners is unnecessary.
  • Castrol Tribol™ OG 500-0 is recommended for the use on slow-moving, heavily loaded open gears.
  • It is also used to lubricate rack-and-pinion gears, wire ropes, slides, cams and other machinery in mills and
    mines and other heavy industries.
  • Temperature range: -20°C up to + 120°C, +140°C intermittent.
  • Castrol Tribol™ OG 500-0 forms a very tough lubricating film on friction surfaces.
  • This stable film offers excellent resistance to high loads even at slow speeds. In the FZG special test for grease
    (A/2.76/50) Castrol Tribol OG 500-0 reaches a scoring load stage of >12 with an extremely low specific wear of
    <0.20 mg/kWh.
  • No additional wear on pistons or plugging of nozzles of automatic spray systems, as Castrol Tribol™ OG 500-0
    does not contain solids.
  • Regeneration of damaged frictional surfaces can occur on a microscale range.
  • The lubricant film is resistant to weather and environmental influences.
  • The stable protective lubricant film is easily and economically applied through automatic dispensing systems
    over a wide temperature range: -20°C up to + 120°C, 140°C intermittent.
  • Increased life of machinery and lubricants.
  • Extended lube intervals, reduced consumption and consequential reduction of maintenance and repair costs.
