CASTROL OPTIGEAR SYNTHETIC RO 150/220.
Synthetic high-performance, long-term gear oil with MICROFLUX TRANS, the load-active
additive combination
Description
Optigear Synthetic RO is a special high-performance, long-term multigrade oil developed especially
for gears used in rail traffic and mechanical engineering applications, with a view to extreme climate
conditions and long-term use. The Microflux Trans additive combination is free of solid lubricants,
adapts even to rapidly changing conditions and actively reduces wear – even under the most severe
application conditions. Can be used in a very broad range of temperatures (no preheating needed in
winter).
Applications
All types of spur gear teeth, also under difficult load conditions.
Bevel gear units, including those with a large offset (hypoid) and heavy alternating loads.
All types of roller bearings, with heavy loads and low and high temperatures.
Dip lubrication at high numbers of revolutions, as well as injection and oil mist lubrication.
Benefits
· High pressure absorption and excellent wear protection
· Safe bearing lubrication in high- and low-temperature ranges
· High seizure load-bearing capacity
· Above-average application times – even under difficult conditions
· Reduction of friction coefficient and operating temperature
· Good corrosion protection
· Long service life for gears
· Exceeds requirements regarding wear protection in line with DIN 51517, part 3Note on application
Can be mixed with lead-free mineral gear oils in any mixing ratio, compatible in operations.
Full performance range only in undiluted application, however.
No influence on usual sealing materials or paint in gear casings.
Filtering (mechanical) does not result in any additive loss.
Not for synchronised gears or limited slip differentials due to low friction coefficients.
