Oil and air lubrication units

Principle of a SKF Oil+Air lubrication system
Principle of a SKF Oil+Air lubrication system

Main areas of application are mechanical engineering applications with demanding requirements for a defined lubrication. Lubrication helps to achieve a high degree of efficiency with minimal wear and long life, particularly in relation to tool spindles.

How it works: A flow of air inside a narrow tube teases a droplet of oil apart to form streaks that are then transported to the lubrication point. A nozzle continually supplies the bearing with oil in the form of fine droplets. The transporting air stream is practically oil-free upon leaving the bearing.

Components of an oil+air system:

  • Oil+air metering unit with built-in piston distributors (injection oiler) - model OLA72 as an example


  • Compact unit with gear pump and the set of valves required for pressure relief and limitation, with oil pressure switch, float switch and control unit - model OLA02 as an example


  • Pressure control valve for air
  • Pressure gauge for the air pressure
  • Pressure switch for min. air pressure
  • Oil streak sensor GS4011 or GS6011

The components can be supplied as a complete unit (model OLA) or individually. Purchasing individual components makes sense if the lubrication system is not going to be installed on the machine as a complete unit (e.g. for reasons of space).
