SKF TER-144 Bearing Seal

SKF TER-144 Bearing Seal, commonly referred to as the TER 144 Taconite Seal, is a purpose-built, large-diameter shaft seal designed to guard heavy-duty bearing housings against contaminants and lubricant loss in demanding industrial environments. Key dimensions include a 6.25 in (158.75 mm) bore, a 7.75 in (196.85 mm) outer diameter, and a 2.25 in (57.15 mm) overall width, making it suitable for sizable equipment retrofit or new installations where a robust sealing solution is required. The seal’s stack-up combines a steel enclosure with felt packing and a nitrile rubber sealing lip, delivering a balanced seal that resists particle ingress while maintaining reliable grease retention during long service intervals. As part of SKF’s Taconite line, TER-144 is a specialized option for large-bore sealing in industrial machinery, providing a durable, low-maintenance solution for critical sealing needs.
