For the extrusion gaps, SKF recommends machining the fits according to the following tolerance classes: F8and H9 for diameters up to 120 mm. F7and H8 for diameters larger than 120 mm. Diagrams 1 to 3 provide guideline values for the maximum extrusion gap in relation to the operating pressure for standard O-rings without back-up ring ( diagram 1

Designing the parts of an application where o-rings will be applied is broadly termed “o-ring groove design”. In order to seal properly, the o-ring has to 

12. O-ring Gland Design The following pages contain basic O-ring gland design information. Please contact the local ERIKS repre-sentative if an application does not clearly fall into these design parameters. Static Applications There are five types of static O-ring applications: • Flange seal • Radial seal • Dovetail seal • Boss seal

THE O-RING EXAMPLE Throughout this guide, the o-ring is used as an example in our discussion of seal design principles. We have made this choice for these reasons: 1. It is the most common and most widely known type of seal in use today. 2. It is used in all types of applications and by a broad range of industries. 3.

O-ring design guides for engineers are helpful resources to find the exact o-ring material specifications needed. O-ring design guides, sizing charts, chemical compatibility guides and more explain the performance attributes of different o-ring materials.

O-Ring Groove Design Guides Expert Application Engineering Assistance O-ring groove design guides offer default dimensional guidance on the most basic o-ring groove design applications. The best o-rings are useless without the right groove design which becomes increasingly important the more demanding the application environment.

DESIGN ENGINEERS’ O-RING SIZE GUIDE INTRODUCTION: Substantially all O-ring manufacturers present their catalog data in the rotation of “groupings” or “families” of cross-sectional thickness first, then followed by dimensions of inside diameter.

O-Ring Basics; Seal Thinking™ Elastomer seals are unlike any other materials that design engineers confront. Metal or plastic parts, for instance, are probably failing if visibly distorted. But, an o-ring MUST be deformed to function properly. In fact, an o-ring that is not squeezed and stretched in its application is the wrong o-ring.

O-Ring Gland Fill %O-Ring Volume) / (Gland Volume) Gland volume vs. O-Ring volume. About 25% void space or 75% nominal fill. Need space in groove to allow for volume swell, thermal expansion, and increasing width due to squeeze. Narrower groove for sealing vacuum or gas. O-Ring can extrude into clearance gap or get squeezed in two directions.

O-Ring Basics. An O-ring is a torus, or doughnut-shaped ring, generally molded from an elastomer. Material Selection Guide; Static O-Ring Sealing. It has been said that O-ring are "the finest static seals ever developed. Parker's Design Tool & O-Ring Calculator.

BACK-UP RINGS (Design Chart 7) When you have a tendency for O-rings to extrude between the sealing areas under pressure, there are three choices available to minimize this: 1. A harder O-ring material may be used. 2. Clearances may be reduced to a minimum. 3. Back-up rings may be used.

O-Ring Design Guide. O-Rings continue to be the most widely utilized sealing product. While the ‘Donut’ shaped profile has by and large been kept intact since their inception, continued elastomeric development has pushed O-ring temperature and chemical compatibility to limits unimaginable several decades ago.
