Description
Castrol Optigear™ Synthetic PD...ES Range is based on synthetic hydrocarbons (PAO) with Castrol's advanced gear oil
system which gives special plastic deformation (PD) and surface improvement performance. The additive package,
when activated by high specific loads and corresponding temperatures, helps to equalize surface roughness without
creating abrasion leading to the surface improvement (plastic deformation).
Optigear Synthetic PD...ES is a CLP-HC gear oil (according to DIN 51502) and exceeds the minimum requirements
according to DIN 51517, part 3, CLP gear oils and is formulated with detergent type additives.
Optigear Synthetic PD...ES is classified as follows :
DIN 51517-3 for CLP gear oils
DIN 51517-4 for C LPX gear oils
Optigear Synthetic PD 150 ES to PD 460 ES gear oils are approved by Flender (Flender gear units - Listing T 7300, Rev.
16, formerly Siemens Mechanical Drives).
Application
Castrol Optigear Synthetic PD...ES may be used in spur gear, bevel gears or planetary gear units and in heavy loaded
gear units. It is also suitable for the lubrication of oil-lubricated rolling bearings. It is especially designed to reduce
friction losses and can reduce energy consumption compared to more conventional lubricants. The lower
friction observed with Optigear Synthetic PD...ES means less stress in the contact point subsurface area, which means
lower risk for pittings and micropittings.
Being synthetic based it will also withstand higher temperatures and provide extended life. Depending on the specific
application, Optigear Synthetic PD...ES may be used in an operating temperature range from -40°C to +100°C, and up to
+120°C for short periods. (Note the lower operating temperature is dependent on the pour point).
