Four-lip seals

Easy-to-install, high-speed solution

With shaft speeds continuously increasing, there was a need for a sealing solution that could accommodate higher speeds with the same high level of performance that the SKF double-lip seal could provide at lower speeds.

To meet that need, SKF developed a robust, easy-to-mount four-lip seal that can accommodate peripheral speeds up to 13 m/s. This four-lip seal is made from a specially formulated thermoplastic elastomer. It is manufactured using a unique process that improves the finish of the contact surfaces so that there is less friction and heat generated by the seal.

These four-lip seals, which are designed for grease lubrication, can accommodate speeds up to 13 m/s even if the housing uses a grease escape hole. The seals are also split for easy installation.
