Sealmaster SF-20T Flange Mount Bearing Unit is a fixed (non-expansion) ball bearing assembly with a 1-1/4 in bore. It uses a four-bolt flange for secure surface mounting and a cast-iron housing for durability in industrial environments, and it features a felt labyrinth seal to resist contamination while preserving lubrication. The unit employs a concentric collar locking system for precise shaft retention, delivering a reliable, standard-duty flange-bearing solution designed for compact, easy mounting in equipment that requires rigid, stable shaft alignment.
