These seals (photo) are available fully split to retrofit mixers, blenders and most other rotating bulk process equipment without the removal of bearings or drives. The seals work like a thrust bearing; there are no internal springs to loosen, corrode or break. A driving elastomer is the seal’s only contact with the shaft protecting it from abrasion damage. Radial shaft misalignment and shock loads are accommodated, as well as thermal shaft growth in high-temperature processes. A minimum of 6 mm of total runout-misalignment capacity is built into the seals. — MECO Shaft Seals, Div., Woodex Bearing Co., Georgetown, Maine
