AMSOIL Industrial EP Series-MPT Micropitting-Tech Extreme-Pressure Gear Oil is engineered to protect gears and bearings operating under severe-service and shock-loading conditions. It provides advanced micropitting protection technology with an emphasis on extreme-pressure gear protection and heat resistance to provide complete gearbox protection.
- Superior film strength for advanced micropitting protection.
- Excellent extreme-pressure wear protection.
- Outstanding protection against shock loading.
- Quick air release to maintain a thick lubricating film.
- High thermal stability to prevent sludge and deposits.
- Inhibits corrosion to maximize gear and bearing life.
