Function

A rotating thread drive (lead screw with ESBF-LS or ball screw
with ESBF-BS) converts the rotary movement of a motor into a
linear movement. The piston rod will then move backwards and
forwards.
The piston rod is non-rotating. The position of the piston rod
can be scanned with the aid of proximity sensors.
Note
The ESBF-LS is self-braking. When the input torque is not applied, the piston rod will be
braked.
The piston rod can, however, move involuntarily when:
– Vertical or diagonal mounting position of the ESBF-LS
– there is no holding torque on the drive shaft
– vibration
Note
The ESBF-BS is unbraked. When the input torque is not applied, the piston rod can be
moved freely. Self-locking of the complete system can be achieved with motors with
integrated holding brake or with high self-braking torque.
• Select the corresponding motors from our catalogue (è www.festo.com/catalogue).
• Do not exceed the limit values for forces and speeds when using other motors (è 12 Technical data
and 13 characteristics curves in Appendix).

Transport

• Take product weight into account (è 12 Technical data).
• Secure piston rod during transport and maintain it in load-free position.
