Heavy-Duty
Hydraulic Cylinder

When the application demands a heavy-duty
cylinder with maximum performance, specify
Atlas Series H. This cylinder has standard
design features to maximize machine uptime.
The standard bronze rod gland, case-
hardened piston rod, high strength piston
rod stud and tie rod material combine to
make Series H the cylinder for demanding
applications up to 3000 psi.

Thorough inspection and performance
testing of each cylinder before shipment
assure Series H cylinder quality. See the
following pages for the inside story on all
the features that make Series H the high
performance, long lasting choice for all your
heavy-duty hydraulic applications.

clevises.
5 Eye Brackets with pin diameters 0.500 thru 1.375 are forged steel. Eye Brackets with 1.750 pin diameter and larger are cast ductile iron.
