Rotary shaft lip-type seals incorporating thermoplastic sealing elements - Part 3: Storage, handling and installation

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds, based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low pressure conditions. This part of ISO 16589 gives users of lip-type seals guidance on the careful storage and handling and proper installation of rotary shaft lip-type seals; attention is drawn to the hazards involved and ways of avoiding them are pointed out.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 16589-3 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 7,

Sealing devices.

This second edition cancels and replaces the first edition (ISO 16589-3:2001), which has been technically

revised.

ISO 16589 consists of the following parts, under the general title Rotary shaft lip-type seals incorporating

thermoplastic sealing elements:
⎯ Part 1: Nominal dimensions and tolerances
⎯ Part 2: Vocabulary
⎯ Part 3: Storage, handling and installation
⎯ Part 4: Performance test procedures
⎯ Part 5: Identification of visual imperfections

ISO 16589-3:2011(E)
Introduction

Rotary shaft lip-type seals are used to retain fluid in equipment where the differential pressure is relatively low.

Typically the shaft rotates and the housing is stationary, although in some applications the shaft is stationary

and the housing rotates.

Dynamic sealing is normally the result of a designed interference fit between the shaft and a flexible element

incorporated in the seal.

Similarly, a designed interference fit between the outside diameter of the seal and the diameter of the housing

bore retains the seal and prevents static leakage.

Careful storage and handling and proper installation of all seals are necessary to avoid hazards, both prior to

and during installation, which would adversely affect service life.

1 Scope

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds,

based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for

use under low pressure conditions.

This part of ISO 16589 gives users of lip-type seals guidance on the careful storage and handling and proper

installation of rotary shaft lip-type seals; attention is drawn to the hazards involved and ways of avoiding them

are pointed out.

NOTE ISO 16589 is complementary to ISO 6194, which covers seals incorporating elastomeric sealing elements.

2 Normative references

The following referenced documents are indispensable for the application of this document. For dated

document (including any amendments) applies.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 5598 and ISO 16589-2 apply.

4 General storage

4.1 Rotary shaft lip-type seals need to be stored with caution because any damage to them can adversely

affect their life and subsequently the service life of bearings and/or other costly machined parts. They shall be

stored in accordance with ISO 2230; in addition, the requirements given in 4.2 to 4.6 apply.

4.2 Seals shall be protected from insects and rodents, some of which thrive on rubber products.

ISO 16589-3:2011(E)

4.3 Lip seals should be stored in a place other than a work area to avoid possible mechanical damage by

equipment or falling objects. A closed container will provide protection from mechanical damage, as well as

from dust, grit and other contaminants.

4.4 When cartons of lip seals are stacked, take care to avoid damage to the bottom parts due to excessive

weight.

4.5 Rotary shaft seals incorporating thermoplastic sealing elements can be supplied assembled on

mandrels for ease of transport and storage. These mandrels have the advantage of protecting the sealing lip

and preventing relaxation of the lip which could result in increased interference. When this is the case, the

seals shall remain on mandrels until immediately prior to installation. In some cases, the seals are supplied

with individual mandrels that can be used as assembly tools. The seal manufacturer should ensure that the

seal/seals are assembled onto mandrels backside first, unless individual mandrels are supplied. The user

should withdraw the seal from the mandrel backside first.
4.6 Seals shall
