Super Gear EP
- SK SUPER GEAR EP is a high performance industrial gear oil of extreme pressure (EP) performance developed for heavy load carrying gears working under severe operation condition. It significantly reduces friction and prevents wear and scuffing, extending gear component lifespan and reduce maintenance cost. It exceeds the requirements of major industrial standards; DIN, US Steel, Cincinatti and David Brown.
General Characteristics
• Outstanding extreme pressure performance to prevent wear and metal stress that occur with increasing loads• Exceptional thermal and oxidation stability to minimize sludge and deposit formation to ensure service life
• Superior rust and corrosion protection film formed on metal surface extending gear component lifespan
Recommendations
Recommended for high-temperature, high-load gears in steel production; industrial gears and rolling gears under high temperature and heavy loads; pulp and paper machine gears requiring demulsification at high temperatureSpecification
