Shell Omala S1 W 680 1*55 GAL DRUM

Shell Omala S1 W oils are quality refined, high viscosity mineral oils compounded with a small percentage of fatty oils. They are particularly suitable for the lubrication of low-speed enclosed gears and worm drive application. They are also suitable for the lubrication of high temperature, high pressure steam cylinders.

Wear Protection

• Provides a strong and reliable oil film under low-speed operating conditions.
• Effective for protecting worm gear drives against wear.

Main Applications

• Enclosed industrial worm gear systems.
  • Suitable for worm gears prone to high wear and heat buildup.
  • Helps reduce bulk oil temperature in operation.
  • Ideal for low-speed, stop-start operating conditions.
• Steam cylinder lubrication.
  • Designed for high-temperature and high-pressure steam cylinder environments.

Recommendations / Alternatives

• For highly loaded worm drives: use Shell Omala S4 WE.
• For enclosed spur and helical gears: use Shell Omala “G” series.
• For automotive hypoid gears (axles and differentials): use Shell Spirax oils.

Operational Efficiency

• Reliable lubrication under heavy loads
• Helps reduce bulk oil temperature
• Suitable for demanding intermittent operations

Oil Stability

• Low volatility
• Resists sludge and carbon deposits
• Stable performance in high temperatures
