  • Castrol Molub-Alloy Range: Suitable for various gear types, featuring high shock load carrying capabilities and low friction for increased part life and energy efficiency.
  • Castrol Alphasyn T Range: PAO-based synthetic oils with good thermal stability, oxidation resistance, and water separation, ideal for wet environments.
  • Castrol Alphasyn PG Range: PAG-based oils providing high load capacity, wear protection, and thermal stability for high-load and high-temperature operations.
  • Castrol Alphasyn EP Range: PAO-based oils with micro-pitting protection, high viscosity index, and good demulsification properties.
  • Castrol Optigear BM Range: Mineral-based oils with Microflux Trans additives for wear prevention and energy savings.
  • Castrol Tribol 800 Range: PAG-based oils for highly loaded gears, offering shear stability and extended lubricant life.
  • Castrol Optigear Synthetic X Range: PAO-based oils with advanced additives for extreme conditions, offering wear protection and energy cost reduction.
  • Castrol Tribol 1100 Range: Mineral-based oils with TGOA system for surface smoothing and extended oil drain intervals.
Gear Types and Applications:
  • Spur Gears: Known for noisy operation, limited load capacity.
  • Bevel Gears: Used for 90-degree power direction changes.
  • Spiral Bevel Gears: Provide quiet, smooth power transfer.
  • Herringbone Gears: Handle heavy loads at high speeds.
  • Helical Gears: Quieter and smoother than spur gears, carry greater loads.
  • Worm Gears: Require special additives for high velocity reductions.
  • Hypoid Gears: Used in automotive applications, need EP additives.
Lubrication Guidelines: Selecting the right gear oil involves considering viscosity, chemical stability, service classification, demulsibility, and film strength. Proper lubrication ensures protection against metal-to-metal contact and extends gear life.
Conclusion: Castrol offers a wide range of gear oils tailored to meet the demands of various industrial applications, ensuring optimal gear performance, extended maintenance intervals, and reduced operational costs.

Gear Oils-4

Checklist: Lubricate enclosed gears with gear oil that has: • Proper viscosity - for the size, type and speed of the gears. Also consider operating temperatures and pressures, shock loads, ambient start-up temperatures, as well • Chemical stability - to withstand the heightened tendency to oxidize because of the constant mixing with air at oxidizing temperatures. • Service classification - as specified by the gear manufacturer. • Demulsibility - the ability to separate from water so contaminating moisture can be drained from the sump of the gear case. This reduces rust and corrosion, and limits...
