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.
