Did you know?

The teeth of the ZAPEX ZW are lubricated with oil or grease. Special double-lip sealing rings are used to seal the tooth space. These so-called DUO sealing rings offer double security preventing lubricant from escaping and dirt from entering the tooth space. Thanks to this, a long service life of the coupling can be ensured.
