Threaded body cylinder
type 2A:
with reset spring,
with double wiper

Description

These threaded body cylinders are used as space-saving clamping cylinders and are notable for their compact design. By the internal stroke limiters, the cylinder can also be operated even without a counter clamp surface. The use of the double wiper ring reduces dynamic leakage.

The threaded body cylinder is hydraulically operated, single-acting. Return is by means of a build-in spring. The hydraulic oil is fed through drilled holes. The cylinder is sealed against the base of the screw-in hole by means of a ring seal. As a result of the plunger design, bleeding of the piston rod space is unnecessary.

Special features:

diversity due different designs
also retracted fully loadable
ventilation connection unnecessary
with spherical piston surface
without or with double wiper available
standard cylinders and special designs available

Important instruction:

The cylinder can be loaded up to the maximum clamping force in the retracted position. Protect the cylinders against the direct influences of aggressive abrasives and coolants. For general operating conditions and other information, read the document Recommendations & Specifications.

Application example

Multiple clamping fixture for series manufacture

Use in a multiple clamping fixture for series manufacture of different workpieces (eg. flange plates).

The fixture is located on a rotary table. The clamping length is 600 mm.

48 single-acting threaded body cylinders with a piston diameter of 20 mm and a stroke of 15 mm are used, and a rotary valve coupling, single-acting with 6 stations with a nominal diameter of 5.
