💡 What is a double-row sealed roller bearing used for in sheave and pulley systems? This bearing type is handy when you need compact, heavy-load support and reliable sealing. - Ideal for sheaves, pulleys, hoists and conveyor drums where sealed ball bearing replacements might not handle the same loads - Keeps grease in and contaminants out, similar benefit terms used for sealed ball bearing or linear slide unit applications - Offers higher radial capacity than single-row bearings, an alternative to pillow block bearing setups or ceramic options when heat and load capacity matter
