Product Description

Features
Complete Freewheels BD X are sealed sprag freewheels with ball bearings and sprag lift-off
X. They are supplied oil-filled. The sprag lift-off X ensures wear-free freewheel - ing operation when the inner ring rotates at high speed. The freewheels BD X are used as:
Backstops
Overrunning Clutches
for applications with high speed freewheeling operation and when used as an overrunning
clutch with low speed driving operation. Nominal torques up to 42 500 Nm. Bores up to 150 mm.
 
Application example
Complete Freewheel BD 45 SX as an overrunning clutch on the shaft end of the high speed
rotating main drive of a textile machine. The sprocket is linked to an auxiliary drive. In normal
operation (freewheeling operation) the inner ring overruns and the outer ring is at a standstill
with the bolted on sprocket. During set-up, the machine is driven by the slowly running auxiliary drive via the chain drive and the freewheel that is working in the driving operation. With the high speed of the inner ring in freewheeling operation, the type sprag lift-off X is used; the sprags work in freewheeling operation without contact and hence are wear-free.

pilot on the covers is particularly suitable for attaching smaller and narrower parts (sprockets,
gear wheels etc.). The customer must provide fastening screws of the necessary length in order to mount the attachment part. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter R of the attachment part must be ISO H7 or J7.
