Needle roller bearings are roller bearings with slender cylindrical rollers. These bearings are designed for applications where radial space is limited but high radial load carrying capacity is required.Needle roller bearings have numerous types available and many have no inner rings. The 'drawn-cup' type has a pressed steel cage outer ring while the 'solid' type has a machined outer ring. There are also cage and roller assemblies without rings.
