PHILSYN® PG GEAR OIL

POLYALKYLENE GLYCOL (PAG) SYNTHETIC FOR SUPERIOR SLIDING LUBRICITY

Close

PhilSyn PG is a premium, full-synthetic industrial gear lubricant specifically engineered for high-friction applications such as high-ratio worm gears, textile machinery, and high-temperature oven chains. Formulated with polyalkylene glycol (PAG) base fluids, it provides a naturally high viscosity index and unmatched thermal stability, allowing it to operate in temperatures where conventional or PAO-based synthetics would fail. This specialized chemistry offers exceptional lubricity that drastically reduces heat generation and internal friction, protecting sensitive bronze and yellow-metal components from premature wear and pitting. It is designed to resist the formation of sludge and carbon deposits, ensuring the highest level of mechanical efficiency and extended service life for the most demanding, high-torque industrial tasks.

PRODUCT RESOURCES 

PERFORMANCE

  • Superior sliding lubricity drastically reduces internal fluid friction and heat generation.

  • High naturally occurring viscosity index ensures consistent performance across temperature spikes.

  • Optimized for high-friction applications like high-ratio worm gears and textile machinery.

PROTECTION

  • Specialized PAG chemistry protects sensitive bronze and yellow-metal components from wear.

  • Impenetrable film strength prevents premature pitting and surface fatigue under high torque.

  • Exceptional thermal stability prevents the formation of sludge and carbon deposits.

UPTIME

  • Resists thermal breakdown in environments where conventional or PAO synthetics fail.

  • Extended service life reduces oil disposal costs and frequency of maintenance intervals.

  • Maintains internal component cleanliness, preventing the clogging of critical orifices and valves.

FEATURES & BENEFITS

  • Sliding Lubricity: Superior lubricity compared to mineral oils, specifically designed to reduce heat in high-friction worm gears.

  • Thermal Stability: Outstanding oxidation resistance allows for significantly extended service intervals.

  • Yellow Metal Safe: Formulated to be non-corrosive to bronze and brass components often found in gear reducers.

  • High Viscosity Index: Maintains consistent film thickness across extreme temperature swings.

APPLICATIONS

  • Severe-service enclosed worm gearboxes.

  • High-temperature oven chains and textile machinery.

  • Reciprocating gas compressor cylinders where hydrocarbon dilution is a risk.

MAMMOTH TECHNICAL TIP:

CRITICAL: PhilSyn PG (PAG-based) is NOT compatible with mineral oils. If you are switching a gearbox over, you must perform a complete flush. Mixing them will result in a gelatinous mess that will take a shop a week to clean out.
