Choosing the correct gear fluid

Selecting the proper industrial gear lubricant is important for the long-term efficient operation of the gear drive. There are many factors to be considered when selecting a gear lubricant for a particular application.

Applications

Selection criteria are:

  • Gearbox type: Spur and bevel, helical and spiral bevel, hypoid or worm.
  • Operating conditions: Open or closed casing, load, vibration, speed, temperatures (low to moderate between +20°C and +80°C, hot at more than +80°C and extreme in excess of +120°C).
  • Exposure to humidity, dust or other elements
  • Special requirements such as H1 registration
  • Maintenance conditions: long intervals between oil changes to cut cost
  • Materials compatibility.
  • resistance to micro pitting and grey staining
  • Shear stability

These lubrication specifications are designed to balance the lubrication needs of the bearings, which generally require a light-viscosity lubricant. The specifications are also designed to balance the lubrication needs of the gears, which usually require the use of a medium- to high-viscosity lubricant. This balance can only be achieved through proper viscosity selection.
