FXM85-40 High Speed Reducer Backstop Overrunning Sprag Clutch Bearing

FXM85-40 High Speed Reducer Backstop Overrunning Clutch One Way Bearing

Features of FXM85-40 Overrunning Clutch Bearing 

Application as

For application as backstop in installations with high speeds in freewheeling operation.
For application as overrunning clutch in installations with low speeds in driving operation.

Sprag lift-off X

  Integrated Freewheels FXM are equipped with sprag lift-off X. The sprag lift-off X is used for backstops and overrunning clutches, provided that in freewheeling operation the inner ring is rotating at high speed and providing with overrunning clutches that the driving operation is conducted at low speed. In freewheeling operation, the centrifugal force FC causes the sprag to lift off from the outer track. In this operating state, the freewheel works wear-free,  i.e. with unlimited service life. 

Technical Datas of FXM85-40 Overrunning Clutch Bearing

Dimensions and Capacities

Integrated Freewheels FXM are sprag freewheels without bearing support and with sprag lift-off X. The sprag lift-off X ensures a wear free freewheeling operation when the inner ring rotates at high speed. The freewheels FXM are used as:

Backstops

Overrunning Clutches

for applications with high speed freewheel ing operation and when used as an overrunning clutch with low speed driving operation. Nominal torques up to 888 000 Nm. Bores up to 460 mm. Many standard bores are available.

Notes:

The maximum transmissible torque is 2 times the specified nominal torque.

The theoretical nominal torque applies only for ideal concentricity between the inner and outer ring. In practice, the concentricity is affected by the bearing play and centering errors of the neigh bouring parts.

Then the nominal torques specified in the table apply, whilst taking into consideration the existing run out (T.I.R.).Higher speeds upon request.
