Application example
Basic Freewheel FBO 127 SF as an overrunning clutch between the creep drive and the main drive of a cement mixer. In the case of creep operation, the outer ring is driven by the shaft coupling. The freewheel works in driving oper - ation and drives the unit at a low speed via the main gearbox. In normal operation (freewheel - ing operation), the inner ring overruns and the
creep drive is automatically disengaged. The freewheel is connected to the oil lubrication of the main gearbox and does not require any special maintenance. The arrangement of the seals between the freewheel and the main gear box is advantageous. In normal operation(freewheeling operation), this is at a standstill and hence generates no additional frictionrelated temperature rise.
Mounting
The customer connecting parts are centered on the ball bearing external diameter F and assembled via the outer ring. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter F of the connecting part must be ISO H7 or J7. The centering depth C must be observed.
Lubrication
An oil lubrication of the specified quality must be provided.
