DescriptionProduct description:The single-acting screw-in cylinders with spring return are characterised by their compact design and are therefore often used as clamping cylinders. They can be positioned very close to each other. Due to the internal stroke limitation, these screw-in cylinders can be operated without an opposing clamping face. The double wipers installed as standard prevent dynamic leakage and thus increase the service life of the screw-in cylinders. The piston is reset to the initial position by means of an integrated spring.Material:Housing and piston steel.
Seal NBR
Version:Housing black oxidised.
Piston hardened.
Note:The screw-in cylinders can withstand maximum loads in both the tensioned and untensioned state.
To avoid damage to the seals during installation, make sure that the lead-in chamfers as well as the transverse holes for the oil supply are well rounded.
A sealing ring at the bottom of the screw-in hole seals the screw-in cylinder.
Due to the plunger design, no venting of the rod space is required.

The screw-in cylinders should be protected from aggressive cutting and cooling agents.

Thrust pieces for Form B are not supplied.

Follow safety instructions.
