💡 How do double sealed bearings compare to open or partially covered ones?

Open designs spin cleaner but let dust and moisture sneak in fast. Partial covers cut debris but still leak under pressure. Full contact shields lock out grit and hold grease inside, which keeps runout tight and cuts down on early wear. That setup works best when machines run through dirt, heat, or washdown cycles without frequent maintenance stops. ✝️
