Protogear AM Series

Protogear AM Series

Balmerol Protogear AM Series gear oils are extra high performance, micropitting resistant gear oils with excellent load carrying and extreme pressure properties. Today’s modern generation gearboxes operate under severe conditions, have higher power densities and run at higher temperatures, at times leading to microscopic wear known as micropitting. Balmerol Protogear AM Series gear oils are formulated to resist gear failures due to micropitting. Balmerol Protogear AM Series gear oils are fortified with unique micropitting Resistant additives, Antioxidants and Rust & Corrosion Inhibitors.

Balmerol Protogear AM Series provides the following benefits:
  • Micropitting resistant characteristics: Resists gear, bearing & seal failures from the initial stage, leading to lower unscheduled downtime.
  • Lower Deposit formation and superior Oxidation & Thermal stability: Clean performance even during high-temperature operation, ensuring longer oil drain intervals.
Micropitting Resistant Gear Oil provides the following benefits:
  • Very good anti-foam characteristics: Better protection of equipment from foaming-related failures (excessive oxidation, cavitations), as well as better housekeeping.
  • Very good Rust protection & Demulsibility characteristics: Easily sheds off water from the oil and ensures better component protection.
Applications / Recommendations:
  • Balmerol Protogear AM Series gear oils are recommended for use in enclosed industrial gears with splash / circulation lubrication, heavily loaded plain and rolling contact slow speed bearings and gear couplings where operating or bulk oil temperatures are up to 100o C. It is especially suitable for bevel and spur gears working under heavy / shock loads. Balmerol Protogear AM Series gear oils are compatible with metallic, as well as elastomeric seal materials
