Foreword

This catalogue contains the standard assort-ment of SKF hydraulic seals and guides typic-ally used in hydraulic cylinders. To provide the highest levels of quality and customer service, these products are available worldwide through SKF sales channels. For information about lead times and deliveries, contact your local SKF representative or SKF Authorized Distributor.

This catalogue reflects SKF’s state-of-the-art technology and production capabilities as of 2014. The data contained within may differ from that shown in earlier catalogues because of redesign, technological developments, or revised calculation methods. SKF reserves the right to continuously improve its products with respect to materials, design and manufactur-ing methods, some of which are driven by technological developments.

Getting started

Introduction to fluid power provides an over-view over hydraulic cylinder types and classi-fication, a reference to SKF customized solu-tions and standard assortment of hydraulic seals and guides. The first chapter contains general technical information. Seal counter-surface finish properties, materials, fluid media and gap extrusion are discussed in detail. Furthermore, product storage and installation information is included.

Guidance values

Since several factors simultaneously affect the sealing system and seal performance, all stated values in graphs and tables in this pub-lication should be considered as guidelines only and not as absolute values for practical applications.

The catalogue follows an easy principle:

• Introduction to fluid power († pages 12 to 18) provides basic information about hydraulic seals. • Chapter 1 († pages 21 to 43) provides

general technical information, such as counter-surface finish properties, materi-als, fluid media.

• Chapters 2 to 6 provide product type specific information. If applicable, a profile overview at the beginning shows the different profiles with a brief description and reference to more information inside the chapter. Product type and profile characteristics are discussed in detail. The profile data tables provide product specifications per profile followed by the relevant product tables with dimen-sions per item. At the end of the chapter more profiles of the specific type are out-lined, including examples of the machined seal profiles manufactured with the SKF SEAL JET technology.

• Chapter 7 († pages 347 to 351) provides some information on other types of fluid power seals used both in hydraulic cylinders and other applications.

• Chapter 8 contains the product index († page 352) sorted by the profiles.

Find product details quickly

Blue tabs on each right hand page show the chapter or product table number.

A quick way to access detailed product data is via the product table numbers. They are listed in the full table of contents at the front of the catalogue, in the table of contents of each product chapter and in the product index.

Units of measurement

This catalogue is for global use. Therefore, the predominant units of measurement are in accordance with ISO 80000-1. Imperial units are used whenever necessary. Unit conver-sions can be made using the conversion table († page 4).

For easier use, some values are provided in both metric and imperial values. Values are typically rounded. Therefore, the two values do not always match according to the conver-sion formula.
