Application example
Complete Freewheel BM 40 R as an overrunning clutch on the shaft end of the main drive of a
paper processing machine. The pulley is connected to an auxiliary drive. In normal operation
(freewheeling operation) the inner ring overruns and the outer ring is at a standstill with the
attached pulley. During set-up (driving operation) the machine is driven by an auxiliary drive
via the pulley at a low speed.
Mounting
The customer attachment part is connected via a keyway connection with the outer ring. The
customer must provide the key required for assembling the attachment part. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter D of the attachment part must be ISO H7 or J7.
