💡 What is a flange bearing used for in industrial machinery? Flange bearings give quick, stable shaft support and simple mounting to frames and housings. Quick summary: - Supports radial loads and keeps shafts aligned for conveyors, motors, and gearboxes, compatible with sealed ball bearing designs - Makes maintenance easier with relubrication ports and contact seal options for dusty or wet environments - Often paired with linear slide units or used as a pillow block alternative where compact flange mounting is needed
