💡 What is a 3-bolt flange ball bearing used for in washdown and wet applications? A 3-bolt flange ball bearing provides compact, fixed-mount shaft support with easy bolting and straightforward maintenance. It’s handy for environments that need corrosion resistance, drainage, and periodic relubrication. Quick overview: - Supports shafts in conveyors, roller systems, and linear slide unit setups where mounting footprint is limited - Sealed ball bearing variants or contact seals keep contaminants out while grease fittings allow relubrication - Polymer housings plus stainless inserts resist corrosion in wet or washdown conditions; ceramic options offer extra corrosion and wear resistance
