FAQ - What are Cylindrical Bearings & Their Use? | GGB
Plain cylindrical bearings are made to handle heavier loads and higher speeds than ball bearings and cylindrical roller bearings, both of which are bearings with rolling elements. This is because plain cylindrical bearings have more contact surface area than rolling element bearings, so loads are more evenly distributed across the surface.
