50mm Shaft Size NFR50 Roller Type One-way Bearing as Backstop for cooling tower NFR 50 > >


Description of 40mm Shaft Size NFR40 Roller Type One-way Bearing as Backstop for cooling tower
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. Above size 20,
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.
