💡 What is a 2-bolt flange sealed ball bearing used for in conveyor and linear slide unit setups? A 2-bolt flange sealed ball bearing provides fixed, low-friction shaft support and keeps grease in while keeping dirt out, handy for belt conveyors, gearboxes, and linear slide units. - Commonly used for shaft mounting in conveyors, feeder lines, and light industrial drives, providing rigid flange support and sealed protection - Suits linear slide unit setups and pillow block adapters where a sealed ball bearing and relubrication option are required for uptime - Works well in agricultural and material handling gear where polymer housings resist corrosion and zinc-plated inserts add wear resistance
