Needle roller bearing HK5528 carries radial loads within a thin drawn cup construction, single row, fitted with a cage, open at both ends. Outside diameter is 63.0 mm, width 28.0 mm, and net mass 104.634 g. The limiting speed is 4850.0 1/min, with a reference speed of 3700.0 1/min. The open-end design allows the shaft to pass through both sides of the cup, which simplifies axial positioning where a shoulder or adjacent component defines the running surface. As the bearing is supplied without sealing, the mounting must provide protection against contamination and ensure adequate lubrication of the raceway, either with grease or oil, depending on the operating conditions. The caged needle set reduces friction between rollers and supports operation up to the stated limiting speed.
