At Arrow Engineering we stock a range of Rotary Shaft Seals. Also known as an oil seal, shaft seal, lip seal, this is a simple device designed for excluding dust, water or any other contaminants whilst retaining lubricant in rotary shaft equipment. Despite their simplicity, these are incredibly important and useful products. Their development means we can guarantee the protection of the bearings of rotating shafts.
They work by placing the flexible lip against the rotating part whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lips require some form of lubrication to avoid overheating and are usually energised by means of a garter spring.
