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. ISO 16589-3:2011 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.

Overview

ISO 16589-3:2011 provides practical guidance for the storage, handling and installation of rotary shaft lip-type seals incorporating thermoplastic sealing elements (for example PTFE-based seals). Part 3 of ISO 16589 focuses on avoiding damage and hazards that shorten seal life or compromise equipment (bearings, housings, shafts) and complements dimensional and vocabulary parts of ISO 16589.

Key topics and requirements

• Storage practices
  • Store seals per ISO 2230 and protect from dust, grit, insects, rodents, radioactive materials and harmful fumes.
  • Keep seals in a dedicated, non-work area or closed containers to prevent mechanical damage and contamination.
  • Avoid excessive stacking weight that could deform packaged seals.
• Packaging and unpacking
  • Protect seals during transport and storage; do not remove from packaging until ready for installation.
  • Unpack carefully to avoid cuts or nicks from knives or tools.
• Handling loose parts
  • Do not hang seals on nails or thread them on wires; avoid contact between metal edges and sealing elements.
  • Keep seal surfaces free of abrasives; use manufacturer-recommended cleaners and avoid abrasive or incompatible solvents.
• Installation
  • Inspect seals before fitting; seals can often be installed unlubricated unless supplier specifies lubricant type/amount.
  • Provide lead-in chamfers on shafts and housing bores as specified in ISO 16589-1.
  • Use proper installation tools (bullet‑nosed or special tools) to avoid lip damage and ensure squareness with the bore or shoulder.
  • When press-fitting components over the running area, reduce shaft diameter in the running area by 0.2 mm to avoid damaging the lip.
  • For low-temperature assembly, restore lip flexibility by immersing seals 10–15 minutes in a compatible fluid not exceeding 50 °C.
• Replacement guidance
  • Always fit new seals when replacing; shift the new seal lip to the fluid side so it does not engage the previous wear track.

Practical applications

• Ensures long service life of rotary seals used in low-pressure rotating applications: hydraulic/pneumatic machinery, pumps, motors, gearboxes and other OEM equipment where PTFE/thermoplastic lip seals are used.
• Useful for maintenance teams, assembly technicians, quality engineers and procurement to reduce leakage risk and costly secondary damage (bearings, shafts).

Who should use this standard

• Seal manufacturers and suppliers
• Maintenance and reliability engineers
• OEM design and assembly teams
• Procurement and quality assurance personnel involved in sealing component specification and handling

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.

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.

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.
