Castrol Optigear Synthetic X 320 WTO Synthetic Gear Oil
Castrol Optigear™ Synthetic X 320 WTO is based on synthetic hydrocarbons and a special plastic deformation (PD) and surface improvement additive package. The additive package, when activated by high specific loads and corresponding temperatures, helps to equalize surface roughness without creating abrasion leading to surface improvement (plastic deformation).
Optigear Synthetic X 320 WTO is a CLP-HC gear oil (according to DIN 51502) and exceeds the minimum requirements according to DIN 51517 (2003), part 3, CLP gear oils.
Optigear Synthetic X 320 WTO may be used in spur gear, bevel gears or planetary gear units and in heavy-loaded gear units, e.g. wind turbine main gears. It is also suitable for the lubrication of oil-lubricated rolling bearings.
Depending on the specific application, Optigear Synthetic X may be used in an operating temperature range from -35 °C to +95 °C.
Castrol Optigear Synthetic X 320 WTO Synthetic Gear Oil Product Advantages:
- High load-carrying capacity.
- Superior micro pitting protection.
- Excellent friction reduction.
- Good filtration properties.
- Excellent bearing lubrication suitability.

Optigear Synthetic X gear oil can be applied by an oil can, oil cup reservoir, splash, spray mist or by automatic dispensing equipment and central or circulation systems.
It is compatible with mineral oils and esters. This means that traces up to 3% of previous oil in the gear case after draining will not pose any problems.
However, the beneficial effects of the special PD additives are reduced when mixed with other gear oils.
To achieve an optimum Lifetime of your elastomer seals we recommend the use of Viton (FKM) based materials.
The product should not be stored at temperatures over 60°C. It should be kept away from sunlight, intense cold and extreme temperature fluctuations. If possible, the packaging should not be exposed to the elements. Otherwise, the drums should be laid horizontally to avoid any contamination from water and to prevent the product’s label from rubbing off.
All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and damage to drum markings. Products should not be stored above 60°C, or exposed to hot sun or freezing conditions.
