AIR6082: Calculations to Determine Dimensions for Backup Rings to AS5781, AS5782, AS5860, AS5861 - Information Report

Features

Issuing Committee: A-6C2 Seals Committee

Scope

Content

This AIR documents the methodologies used to calculate the dimensions and tolerances used in the following backup rings standards:

AS5781
AS5782
AS5860
AS5861

In addition, an appendix is provided which provides details of gland and backup ring design practices.

Rationale

Content: Previous parts standards that were originally developed for backup rings used dimensions that were based only on the fit to hardware and O-ring dimensions at ambient. However, backup rings to AS5781, AS5782, AS5860, AS5861 were designed to suit practical operating conditions and machining capabilities of the material. Thus, there is a requirement for a document that provides the means to determine the dimensions for these backup rings. This document has been compiled to meet this need.
