INA HK5520-HLA 55mm I.D Drawn Cup Needle Roller Bearing, 63mm O.D

Are particularly suitable for Applications with a very small radial section height on account of their very low cross-sectional height
Are used if the housing bore is not suitable as a raceway for needle roller and cage assemblies
Can support high radial loads (are pure radial bearings)
Require a considerably smaller radial design envelope than machined needle roller bearings
Usually run directly on the shaft (no inner ring)
Permit relatively high speeds
Are easy to mount
Require no additional means of axial retention (as a result of which the housing bore is easy to produce)
Can be readily used to close off the shaft ends of bearing positions (drawn cup needle roller bearings with closed end)
Result in particularly compact, cost-effective and economical bearing arrangements
