Synthgear MR Series
Balmerol Synthgear MR Series is fully synthetic industrial gear / circulating oil developed for maximum protection of gears and bearings operating under severe conditions and extremes of application temperature. Balmerol Synthgear MR Series is fortified with Anti-micropitting additives and its selective additive system provides protection against scuffing wear and micropitting due to fatigue. The high viscosity index of these products ensure optimum viscosity both at high and low temperatures, which not only provide wider operating temperature range but also ensures equipment protection at extreme temperatures by providing sufficient oil film.
Available Size:
500ml 1L 0.35l
Features & Benefits:
- Protection against micropitting, providing excellent protection of gears and bearings at extreme scuffing wear conditions, meeting various OEM requirements.
- High Viscosity Index, ensuring optimum viscosity/film thickness at operating temperatures for better equipment protection at both low and high temperatures.
- Wider operating temperature range, contributing to excellent oxidation and thermal stability.
- Longer oil drain interval and lower oil consumption, enhancing overall equipment performance and promoting cleaner operation.
- High load carrying characteristics, offering better protection of equipment under heavy/shock loads.
- Very good rust and corrosion protection, leading to lower maintenance costs and better protection of bearings.
Applications / Recommendations:
- Recommended for use in industrial gears and bearings operating under extreme conditions—temperature, pressure, shock loads, etc.
- Compatible with metallic materials as well as elastomeric seals.
- Balmerol Synthgear MR 320/460 are suitable for use in wind turbine gearboxes.
