ESBF-BS
Pressurising and exhausting the pressure compensation opening for variant ESBF-...-S1/F1:
• Screw a G1/8 fitting into the thread 4.
• Use a tube for the supply and exhaust of fresh air.
The exhausting process should be conducted in a protected
area (free from dust and moisture) or in a large pressure
reservoir. Alternatively, a slight excess pressure
(max. 0.2 bar) can be applied as sealing air.
Fitting in a vertical or sloping position:
Warning
Uncontrolled moving masses can cause personal
injury and material damage (risk of crushing).
If there is a spindle nut fracture inside the ESBF or
a toothed belt breaks
when using parallel kit EAMM-U (e.g. due to wear),
the effective load will fall down.
• Check whether additional external safety
measures against damage are required
(e.g. toothed latches or moveable bolts). In this
way you can prevent the work mass from slid-
ing down.
• Examine the toothed belt of the parallel kit reg-
ularly for wear
( assembly instructions for the parallel kit).
Installing the effective load
• Place the centre of gravity of the effective load, if possible,
centrally to the piston rod.
• When securing the effective load make sure that no torque
is transferred to the piston rod.
The wrench flat 7 can be used to exert counter pressure.
• Secure the effective load to the piston rod.
The piston rod will bend depending on the effective load
( Appendix 13 Characteristic curves).
