Durable NFR40 Roller Type One Way Bearing for Cement Hoist Machinery 110mm Outer Diameter

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.

Applications of one way clutch bearing:

One Way Clutches Sprag Type mainly used as Backstop clutches
Reducers,Flender Gearbox,SEW Gearbox

Overrunning clutch: for multiple-machine drives or to separate the inertia of masses of a driven machine from the driving machine after it has been switched off.

Indexing clutch: which turns a shaft step by step, thus achieving indexed material feed or a variable speed.
