Drawn Cup Needle Roller Bearing Open End Full Complement Needle Roller Set HN2520
Drawn cup needle roller bearings with open ends and with closed end are needle roller bearings with a very small radial section height. They comprise thin-walled, drawn cup outer rings and needle roller and cage assemblies which together form a complete unit. The outer rings adapt themselves to the dimensional and geometrical accuracy of the housing bore.
Basic design bearings:
· are available open (without seals) or sealed on one or both sides (Sealing solutions)
· are available open or sealed (Sealing solutions)
· are suitable for bearing arrangements where they are situated at the end of a shaft
· accommodate small axial guidance forces, because of the profiled design of their closed end
· are suitable for very heavy radial loads at moderate speeds
· are available with open ends and without seals only
Full complement drawn cup needle roller bearings are supplied with a special grease to secure the rollers during transport. However, we recommend re-lubricating after mounting.
