Simmerring and Rotary Seals GlobalCatalog_FST - Handling and assembly of Simmerring

Technical Principles | Informations Techniques Informaciones Técnicas | Princípios técnicos 30 EN Preventing the Simmerring, particularly the sealing lip, from contact with sharp edges and any kind of contamination is essential during handling and installation. The list of possible problems is intended to be of use to the user when handling and fitting Simmerring so that the user can recognize problems and take remedial action in the following areas → Technical Manual – Handling of defects, page 68.

Handling Numerous possible problems have causes that can easily be avoided by some simple steps. In practice, however, the care required during handling is frequently neglected. Some examples from the comprehensive list of issues are: AA Pay attention to damaged packaging AA Leave seals in packaging as long as possible until installation AA Do not leave seals lying around loose AA Protect seals from dust and dirt AA Safeguard seals in a sealed or covered state AA Only use clean grease or oil AA Avoid excessive greasing AA Do not bring sealing edge into contact with a sharp edge or with a damaged installation tool AA Avoid metal chips AA Sharp-edged chamfers on the shaft and bore are not permitted AA Damage and corrosion of shaft and bore are not permitted AA Pay attention to alignment of bore and shaft. Positioning of the seal For most uses only one single seal is necessary. For position- ing of vertical or inclined shafts, the installation of two seals, one behind the other in the same installed direction, is recom- mended for seals that lie below the oil level. The space between the seals is to be used as a lubrication chamber. It is recommended to make provision for re-greasing. The Simmerring can only fulfill sealing tasks and is not suitable as a guide for machine components or for the transmission of axial forces. The Simmerring and accompanying shaft contact surface are greased before fitting in order to ensure lubrication for the initial revolutions of the shaft.
