Conveyor pulley upgrade pays off: up to 5 year service life
Open spherical roller bearings mounted in split plummer block housings fitted with competitor taconite seals supporting conveyor pulleys were suffering premature failures with an MTBF of approximately 18 months. Analysis showed the cause of failure to be extremely contaminated bearing grease. The ultimate SKF Three-Barrier Solution (SKF housings, SKF Taconite Seals and upgraded sealed SKF Explorer spherical roller bearings) was installed to address the problem. MTBF is now expected to be in excess of 5 years.
