Pneumatic oil supply system

For small, high-speed conveyor roller chains

This system delivers a very thin film of oil to the chain surface at specified intervals without contact with the chain. Highly precise oil dosing optimizes oil consumption and associated costs. It's an environmentally friendly solution. No oil mist is created. Contactless lubrication eliminates wear on the oil delivery devices.

SKF pneumatic lubrication solutions deliver precisely measured amounts of oil to chain surfaces without contact with the chain. Lubricant is dispensed at preset intervals. 

Criteria

  • Step less than 25 mm (1 inch) 
  • Lubrication speed is more than two links per second

Choose from a wide range of components and configurations to suit your needs.

The systems use pneumatic metering injectors to deliver a minimal amount of oil to the nozzles. A regulated flow of low-pressure compressed air is also supplied to the nozzles. This air transports and delivers oil through the nozzle tip to the chain surface without creating a mist. The central unit includes the metering nozzles, an air flow control system, a reservoir, and control components such as an automatic controller and solenoid valves. Each nozzle is connected to the central unit via separate oil and air lines. Typically, the system is configured to deliver oil intermittently throughout a full chain rotation.

Vectolub VE1B

The SKF VectoLub system works with volumetric micropumps, which deliver very small quantities of lubricant starting at 3 mm3 at a high frequency to the friction point by the use of a bifluid projection nozzle.

Vectolub VTEC

The SKF VectoLub system works with volumetric micropumps, which deliver very small quantities of lubricant (starting at 3 mm3) at a high frequency to the friction point by the use of a bifluid projection nozzle.
