Piston Seals

Choice of the Sealing Element

Sealing elements have a decisive influence on the design,

function and service life of hydraulic and pneumatic

cylinders and systems.

Note on Ordering

All multi-element standard piston seals, e.g. Glyd Ring r

T, are generally supplied as complete seal sets. The supply

includes the seal and matching elastomer energizing

elements. The O-Ring does not have to be ordered

separately. It is also possible to use other O-Ring materials

from our O-Ring catalogue. In this case, please order the

seal ring and O-Ring separately. We will inform you the

sizes of the O-Ring on request.

This applies equally to the piston seals where leak

tightness, resistance to wear and gap extrusion, resistance

to process media, resistance to high and low

temperatures, low friction, compact form and simple

installation are demanded in order to meet the

requirements of industry for a functional sealing solution.

When ordering the seal ring separately, it is then not

necessary to mention the ”O-Ring material code” in the

Order No. shown in the ordering examples.

The significance of these parameters and their limits is

generally dependent on the requirements of the specific

application. B+S has therefore developed a complete

range of seals which, due to their optimized geometries

and designs and the use of high-quality materials such as

Tur con R and Zurcon R , satisfy the technical and economic

demands of the industry in full.

Older designs of seals no longer contained in this

catalogue naturally continue to be available (see chapter

Non Standard Seals). For all new applications, however,

we recommend the use of the seal types and preferred

sizes

(ISO series, wherever possible)

listed in this

In order to be in a position to select the most appropriate

seal type and material, it is necessary to first define all the

desired functional parameters. Table I can then be used

to make an initial selection of seals according to the

specific requirements of the application.

catalogue.

Other combinations of Turcon R materials and special

designs can be developed and supplied for special

applications in all intermediate sizes up to 2.700 mm

diameter, provided there is sufficient demand.

The second column of the table contains the number of the

page on which further general information together with

specific design and installation instructions on the

particular seal type and materials (or material

combinations with multi-element seals, e.g. Turcon R

Glyd Ring r T) can be found.

The sizes contained in this catalogue are generally

available from stock or can be supplied at short notice.

We reserve the right to modify our supply programme.

Furthermore, attention is drawn to the quality of the

mating surface. We recommend that the limits specified

there be observed, as they have a decisive influence on the

functionality and service life of the system.

The final choice of seal type and material must also take

account of the detailed information on the seal elements.

Please do not hesitate to contact our Technical Department

for further information on specific applications and special

technical questions.

This Catalogue is a compilation of the preferred product

ranges of Busak+Shamban, Sealing Parts and POLYPAC.

All similar products are technically equivalent but

availability and pricing may vary. For further information

please contact your local Busak+Shamban company.
