Seal Design Modifications

Rod and piston seals are available in a variety of design configurations. While standard Lynair cylinders include seals proven to be satisfactory for general purpose use, alternate styles designed to provide specific performance characteristics are available when application require- ments make their use desirable. Seals that offer extended service life, greater sealing efficiency, lower friction, constructed of materials, or in sizes better suited to meet particular design requirements may be specified.

A glass fiber filled teflon sealing ring installed over an elastomer expander provides a long wearing, bidirectional, low bypass piston seal suitable for air or hydraulic service.

Wear rings of similar material are often used with this type of seal. Their use eliminates metal to metal contact between piston and bore surfaces which improves wear conditions and is especially effective when used in models having long stroke length.

Seal construction options are an extra cost feature available upon request in all cylinders. Consult Lynair, Inc. to obtain design recommendations and price adders when this optional feature is being considered.
