How grease time and cost
can be decreased
Open bearings on conveyor pulleys need to be re-greased every week. The refined SKF Three-barrier solution, on the other hand, gives excellent bearing protection and extends greasing intervals to several months.
Better bearing protection
The upgraded SKF Three-barrier solution consists of a new housing variant with a grease-filled cavity, a Taconite seal with flanges for water repelling during washdowns, and a sealed bearing.
With three layers working together, the conveyor pulley bearing is under excellent protection.
Bearing protection in action
Bearing service life doubled and relubrication intervals extended by eight times. The SKF Three-barrier solution is making a real difference to this iron ore mine in Australia.
From weekly to quarterly
A bearing protected by three barriers (labyrinth seal, housing grease and bearing seal) only needs one-tenth of the re-lubrication of an open bearing. The service interval for greasing can therefore be prolonged from once a week to every third month. The cut in greasing time and costs is usually around 90%, and without purging, you can reach up to 99.9%.
The SKF Three-barrier solution is available with SKF LGGB 2 biodegradable, low toxic grease for the second barrier.
