Gulf EP Lubricant SY 150

Synthetic heavy-duty industrial gear oil

Gulf EP Lubricant SY series are premium quality synthetic heavy duty industrial gear oils offering outstanding lubrication performance and load carrying capacity under severe operating conditions including shock loading. These are formulated from Polyalphaolefin (PAO) synthetic base stocks having exceptional oxidation resistance and thermal properties and excellent low temperature fluidity. The combination of naturally high viscosity index base stocks coupled with carefully selected additive technology provides excellent protection against scuffing and resistance against micro pitting fatigue under wide operating temperature range.

Features & Benefits

Outstanding load carrying capability and micro-pitting performance protects gears against scuffing and wear leading to enhanced equipment life and reduced maintenance costs
High viscosity index base stocks provide excellent low temperature fluidity and effective lubrication over a wide temperature range
Superior thermo-oxidative stability provides enhanced system cleanliness and enables longer service intervals
Low traction and enhanced lubricity helps provide extra energy efficiency
Excellent resistance to rust and corrosion protection and good demulsibility ensures trouble free operation at high temperatures and applications encountering water contamination
Good seal and paint compatibility with a wide variety of seals and paints

Applications

Heavy-duty industrial enclosed gear boxes operating under severe conditions like high load, extreme temperatures and wide temperature ranges
Filled for life systems
Bearing and circulation systems where high temperatures are encountered
