Trelleborg Sealing Solutions, a leader in cassette sealing technology, has revolutionized the cassette seal design with its new CSL 1500. This is a unique innovative seal that incorporates opposing sprung lips and a stacked design to reduce friction and wear, extending the seal life while improving contaminant exclusion and static sealing ability.
Originally designed for agricultural and construction equipment, the CSL 1500 has been vigorously tested to prove its reliability. The seal has completed 3,000 hours of slurry and hot oil testing as well as over a year of gruelling field service without leakage. Now being utilized in other application areas, the seal applies innovative seal design to give greatly improved performance.
A stacked design gives more room to add components and permits a larger volume of grease, which serves as a barrier to contamination, while a new oil seal lip provides the superior sealing capabilities expected from a Trelleborg Sealing Solutions product. In addition, a new bonding method leaves a fine finish on the riding surfaces eliminating the need for grinding operations, and a metal case requiring no crimping to keep it together, reduces manufacturing costs. A cassette seal, fully enclosed, is able to perform as an all-in-one oil seal, wear sleeve and dust protector. It is suitable for all heavy duty applications.
The CLS 1500 is designed as a modular system for customized design requests. If a high speed cassette seal for highway or railway applications is needed or improved dust protection over an oil seal is required, this system gives increased flexibility for the customer. The modular system means that it is not fixed to manufacturing in standard sizes or large quantities, opening the door to modifications which improve performance for specific applications and requirements.
