Cassette seals, or unitised seals provide many benefits over a single component lip seal . For example, a typical cassette seal would have an integral wear sleeve which the sealing lip runs on, thus preventing the shaft from being grooved from the sealing lip, and allowing the seal to be replaced without the need to re-grind or sleeve the shaft.
Another major advantage is they have multiple wipers to protect the main sealing lip against external contaminants, such as dirt, dust, sand, mud, etc. This capability is ideal for applications such as Truck axle seals, agricultural tractors, quarry machinery, mining bogies and valve actuators, etc.
CHO have unrivalled experience and knowledge of the design and manufacturing of these types of seals for all types of applications. Many more factors need to be taken into account when designing and manufacturing these seals and usually a combination of lip materials are used to achieve the most cost effective solution.
