Reduced grease contamination for conveyor pulley

15116_1_TaconiteSeals_2
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
