Description
High performance gear oil ISO VG 150
Castrol Optigear™ Synthetic RO150 high-performance synthetic oil (PAO based), developed especially for gears used in rail trafficand mechanical engineering applications (such as in Robots).
Application
- Optigear Synthetic RO 150 can be used for 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.
- Can be used in a very broad range of temperatures (no preheating needed in winter).
- Dip lubrication at high numbers of revolutions, as well as injection and oil mist lubrication.
- Filtering (mechanical) does not result in any additive loss.
- Not for synchronised gears or limited slip differentials due to low friction coefficients.
Specifications / Approvals
- DIN 51517-3 (CLP)
Advantages
- High pressure absorption and excellent wear protection¹
- Safe bearing lubrication in high- and low-temperature ranges
- High seizure load-bearing capacity¹
- Above-average application times – even under difficult conditions¹
- Reduction of friction coefficient and operating temperature¹
- Good corrosion protection¹
- Long service life for gears¹
- Exceeds requirements regarding wear protection in line with DIN 51517, part 3
¹ When compared to conventional gear oils
