💡 What is a 3-bolt flange sealed ball bearing used for in machinery? It provides a ready-to-mount sealed shaft support that keeps grease in and contaminants out. - Ideal for conveyor shafts, fans, pumps and agricultural equipment where sealed ball bearings are needed. - Used as a compact mounted bearing or linear slide unit alternative in medium-duty applications. - Set-screw locking and relubrication fitting (1/4-28 UNF) make maintenance easy and extend service life. - Polymer flange resists corrosion and simplifies installation in tight or electrically isolated setups.
