NFR | Stieber Clutch

Type NFR is a bearing supported roller type freewheel without any sealing. Lubrication and sealing must be provided by the installation. Standard lubrication is oil.

Size 8 to 20 units use steel on steel bearing support from the inner race. Above size 25, two 160.. series ball bearings are used, giving a higher overrunning speed capacity. A typical arrangement is shown overleaf. The inner race is keyed to the shaft. The outer race has a positive n6* tolerance to give a press fit in a housing to H7*. Additional side notches provide for positive torque transmission.The housing must be strong enough to not expand after assembly.
