PTFE Rotary Seals
Within manufacturing limitations, any size seal, inch, metric or a mix of both is available, thus eliminating the need to consult a manufacturers catalogue for tooled sizes. There is no charge for tooling, minimum production quantities or for special tolerances. Extended like for a damaged housing bore or shaft is possible by machining to correct the problem, the selecting one of our seals to meet the new dimensional requirements. Standard Semi-Dual and Dual style seals available in any Outside Diameter from 2.500 inches to 48.00 inches (65mm to 1220mm). Seal Inside Diameter is subject to a minimum producible section.
Also known as an oil seal, shaft seal, lip seal, elastomeric lip seal or any variation of these. It is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Generally it has been developed as a means of protecting the bearings of rotating shafts. The basic principle of sealing is straight forward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energised by means of a garter spring.
