Type NFR is a bearing supported roller type freewheelwithout 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.
