💡 What is a double-row roller bearing used for in heavy-duty motors and gearboxes? A double-row roller bearing is designed to handle higher radial loads and shaft misalignment than single-row bearings, making it handy for industrial drives and gear trains. - Ideal for heavy radial load support in motors, gearboxes, and conveyor systems; works well as a pillow block upgrade - Offers better load distribution than sealed ball bearing or single-row types for longer service life - Easy to relubricate via oil holes and fits typical linear slide unit linkages in machinery
