Standard Specification for Epoxy / Cotton Raw Materials for the Use in Bearing Cages

Abstract

This specification covers basic characteristics required for porous laminated epoxy materials intended for use as instrument and thin-section ball-bearing retainers (cages), as well as the methods of determining these characteristics. It provides guidance with respect to material and test conditioning, performance, verification, and packaging and package marking.

Scope

1.1 This specification covers basic characteristics required for porous laminated Epoxy materials intended for use as instrument and thin-section ball-bearing retainers (cages) and the methods of determining these characteristics.

1.2 Forms—Sheets and Rolled Tubes are recommended forms of laminated material covered by this specification.

1.3 Intended Use—Materials produced to this specification are intended for use as ball bearing retainers (cages). Temperature range is limited to 284°F (140°C) and below

1.4 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
