KIT FOR HYDRAULIC CYLINDERS ISO 6022
ISO 6022 heavy duty hydraulic cylinders
  Component Material Description
Bushing Bronze For each head, two different rod diameters are available.
Supplied with polyurethane, PTFE+NBR or Viton® seals.
The ISO dimensions of the seal grooves allow easy availability of spare parts.
Front head Steel Prepared for adjustable cushioning by means of a non-removable screw, which can also be used for air bleeding.
Equipped with flats every 90 degrees to facilitate additional oil ports or SAE flange connections.
Supplied complete with seals.
The ISO dimensions of the seal grooves allow easy availability of spare parts.
Piston Steel With large bronze guides, for high performance even with radial loads.
Supplied complete with Polyurethane, PTFE+NBR or Viton® seals, depending on the application.
The ISO dimensions of the seal grooves allow easy availability of spare parts.
Rear head Steel Prepared for adjustable cushioning by means of a non-removable screw, which can also be used for air bleeding.
Equipped with flats every 90 degrees to facilitate additional oil ports or SAE flange connections.
Supplied complete with seals.
The ISO dimensions of the seal grooves allow easy availability of spare parts.
Cushioning Hardened steel The original floating ring system guarantees perfect centring between the cylinder head and the cushioning ring and performs the function of a rapid opening in the cylinder return phase.
Made of tempered steel, they guarantee a long life over time, thanks to the coupling with the steel seat of the head.
The specific profile of the cushioning bushing allows excellent cushioning.
 10  Tube E355 In the Prisma area of our website, you can configure and download tube machining drawings according to the specifications of the cylinder.
Cut-to-length tubes ready for machining can be supplied on request.
 11  Chromeplated bar CK45 - 42CrMo4 -
AISI 304 - 20MnV6
In the Prisma area of our website, you can configure and download rod machining drawings according to the specifications of the cylinder.
Several types of cut-to-length chrome bars ready for machining are available on request.
Mountings Steel Flange, ball jointed eye, feet, intermediate trunnions, depending on the desired cylinder's mounting.
The components for cylinder's mounting are supplied with the necessary screws to assemble them to the cylinder head.
All components are realized from a solid steel block in one piece, with the exception of the extended version of the ball jointed eye or male clevis, which are welded directly onto the rear head.
Closing flanges
and counterflanges
Steel Supplied with the required screws to close on the cylinder head.
The closing flange is equipped with holes to remove the bushing from the cylinder head.
