Product Description

NFR Series NFR30 Sprag Type Freewheel One Way Sprag Clutch Bearing

Brief Introduction of NFR One Way Clutch Bearing

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.

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.
