Product Description
Nfr Series One Way Bearing Roller Type Freewheel 
Product 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 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.
