This SAE Standard presents the basic size and tolerance information for the design and manufacture of thrust washers. In most cases, the standard employs nominal figures in both metric and inch-pound units and, therefore, does not necessarily provide exact equivalents.

This SAE Recommended Practice applies to nomenclature of turbocharger parts and terminology of performance.

This recommended practice applies to nomenclature of turbocharger parts and terminology of performance.

This SAE Standard establishes physical properties required of SAE Coarse Test Carbon and SAE Fine Test Carbon and establishes test methods to ensure that these requirements are met.

This SAE Standard defines the normal dimensions, dimensioning practice, tolerances, specialized measurement techniques, and glossary of terms for bearing inserts commonly used in reciprocating machinery. The standard sizes cover a range which permits a designer to employ, in proper proportion, the durability and lubrication requirements of each application, while utilizing the forming and machining practices common in manufacture of sleeve type half bearings. Not included are considerations of hydrodynamic lubrication analysis or mechanical stress factors of associated machine structural parts which determine the nominal sizes to be used, selection of bearing material as related to load carrying capacity, and economics of manufacture. For information concerning materials, see SAE J459 and SAE J460. These suggested sizes provide guidelines which may result in minimal costs of tooling but do not necessarily represent items which can be ordered from stock.

This SAE Information Report is a review of test methods that have been used to evaluate elastomeric hydrodynamic seals. The advantages and disadvantages of each method are discussed. There are ten methods total which include three suggested methods. For those interested in more detailed information on hydrodynamic sealing systems, see 2.2.

Bond, as it relates to elastomeric seals, is defined as “The adhesion, established by vulcanization, between two cured elastomeric surfaces, or between one cured elastomeric surface and one nonelastomeric surface.”1 Vulcanization refers in this case to chemical bonding. Good bond is essential to the function of elastomeric radial lip seals and other precision bonded parts. This SAE Recommended Practice describes a universal bond test fixture developed by the RMA that can be mounted to a conventional tensile test machine. This will allow a quantitative evaluation of bond rather than a merely qualitative one.

The classification system provides a means for specifying or describing pertinent properties of commercial nonmetallic gasket materials. Materials composed of asbestos, cork cellulose, and other organic or inorganic materials in combination with various binders or impregnants are included. Materials normally classified as rubber compounds are not included, since they are covered in SAE J200 - ASTM D 2000. Gasket coatings are not covered, since details thereof are intended to be given on engineering drawings or in separate specifications.

The purpose of this SAE Recommended Practice is to provide a glossary of radial seal terms and nomenclature which are normally encountered in the design, manufacture, installation, testing, inspection, and failure mode analysis of radial seals. The information will aid in the understanding and communication among those people associated with radial seals.
