Syncon®Premium EP Gear Oil

Synthetic PAO-Based Extreme-Pressure Gear Lubricant

Phillips 66®Syncon Premium EP Gear Oil is a premium quality, synthetic, extreme pressure gear lubricant specifically recommended for lubricating the heavily loaded gears and rolling-element bearings in motorized wheel gearboxes found on mining haul trucks. It also is recommended for lubrication of enclosed industrial gear drives operating at extreme temperatures.

Features & Benefits

• Outstanding oxidation resistance and thermal stability at high temperatures

• Outstanding low-temperature properties

• High load-carrying capacity

• Protects against scuffing and wear

• Protects against rust and corrosion

• Non-chlorinated additive system

• Suitable for year-round use

• Extended service intervals compared to conventional mineral oil-based gear oils

Applications

• GE motorized wheels found on mining haul trucks

• Enclosed industrial gear drives operating at very high or very low temperatures, or operating continuously at higher than normal operating temperatures

• Heavily loaded plain and rolling-element bearings operating at extreme temperatures

• Applications where the equipment manufacturer recommends a synthetic extreme-pressure gear oil
