Reduced grease contamination for conveyor pulley

Open spherical roller bearings mounted in competitor split plummer block housings with taconite seals supporting conveyor pulleys were suffering premature failures with an MTBF between 3 and 12 months. Analysis showed the cause of failure to be contamination of the bearing grease. Since the ultimate SKF Three-Barrier Solution (SKF housings, SKF Taconite Seals and upgraded sealed SKF Explorer spherical roller bearings) was installed, there have been no further failures
