Abstract
A seal for a thread drive including several ring parts arranged one within the other, to provide a dependable and compact unit comprised of a few parts. A sealing ring which surrounds and rests against the threaded spindle is comprised of rigid plastic. The sealing ring is a single thread section with axially separated ends which are integrally joined together by a transverse connection which closes the thread gap between the separated ends. A pretensioned tension ring surrounds the sealing ring. A housing ring surrounds both other rings. A wiper or scraper may be located on the sealing ring opposite the transverse connection.
