Features of one way bearing clutches 
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 ROM the inner race. A
bove 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.  The housing must be strong enough to not expand after assembly.
