Our complete units combine ground and hardened rings made of 100 Cr 6, a freewheel clutch insert element, ball- and roller bearing support as complete and compact unit.
The standard type includes an insert element with meander spring of series FE 400 M. Of course the insert element of series FE 400 Z is also available on request - simply add the "Z" to your order. Besides the insert element a ball bearing and a roller bearing is included which provides complete bearing support (type FP and FN). Double sealing and pre-lubrication optional (type FND, FPD).
For proper function of complete units the correct gap size is inevitable. Please note that the correct gap size will be achieved when the clutch is pressed onto the shaft and into the housing with the recommended tolerances only. This is especially important for all thin walled rings.
Double sealed complete units (type FPD and FND) are filled with oil for lifetime. Type FP and FN are rust protected only - no lubrication. For further information please see our indications of lubrication.
