Description
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 20, two 160.. series ball bearings are used, giving a higher overrunning speed capacity.
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.
