Symmetrical seal CNP

Description

The CNP is a single-acting symmetrical seal, made of highly wear-resistant PU, intended for sealing light- and medium-duty hydraulic cylinders. Its symmetrical profile allows it to be used on both the piston and the rod, and even in double-acting cylinders. Thanks to its robust design, it provides good sealing even when the rods and guide rings are worn.

Assembly

Fabric symmetrical seals are fitted in split pistons or open grooves with a retainer ring. Chamfer and remove the sharp edges of the housing so as not to damage the seal, and clean the installation space carefully before fitting. Guide rings or guide strips are recommended for guiding the piston or the rod.

Advantages

Materials

Made of polyurethane (PU) with hardnesses from 92 to 95 Shore A, a material of high mechanical and abrasion resistance that offers excellent performance against hydraulic oils to DIN 51524, mineral-based lubricating oils and greases, and HFA, HFB and HFC fire-resistant hydraulic fluids.

Technical drawing and installation parameters of the CNP symmetrical seals

This technical drawing defines the dimensions and geometric variables required for the correct selection and snap-on installation of the CNP symmetrical seal, a compact one-piece profile with reversible geometry, suitable for both rod and piston. It shows the critical dimensions linked to the specification tables, such as the inside diameter (Ød), the outside diameter (ØD) and the seal cross-section width (b), together with the housing groove width (B), its depth (E), the groove root fillet radius (rs 0.40) and the 20° lead-in angle. Working to these dimensions ensures accurate positioning, installation without distorting the profile and optimum static and dynamic sealing performance in double-acting applications at medium and high pressures.

Three-dimensional view and components of the CNP symmetrical seals

This 3D illustration shows the basic structure of the CNP symmetrical seal in detail. You can clearly see its characteristic element: a one-piece polyurethane body with symmetrical sealing lips, whose radial interference keeps them in contact with the sliding surface even at low pressure. Its compact design and reversible geometry allow it to be used either as a rod seal or as a piston seal, providing effective sealing, good resistance to extrusion and wear, and simple snap-on installation.
