Until now, sealing split Plummer/Pillow bearing blocks has always been an issue. Alignment between the shaft and bearing block can vary significantly. Existing labyrinth rings have very large clearances in order to accommodate the large misalignment but provide little protection against contamination. Contact sealing solutions have very short lives because the misalignment overloads the sealing surfaces. AESSEAL’s revolutionary design for bearing blocks is specifically engineered to absorb the misalignment and maximize the performance of the seal.
