Product Details
MITNIK Track Group/SALT/PPR Structure/Track Shoe Assembly/Track Chain Assembly. MITNIK are committed to providing qualified track groups according to OEM specifications.
MITNIK full range of track groups has been fully proven in various industries (mining, forestry, quarrying, construction and agriculture, etc.) and is suitable for all brands and models of excavators and grabbers.
There are three main types of track groups, which are widely used in different applications: dry type, sealed and lubricated type, and sealed and lubricated type. The first dry type will be rarely used in the future. The sealed and lubricated type is widely used in excavators due to its longer wear life, while the sealed and lubricated type is becoming more and more popular and widely used in other demanding applications of bulldozers. Compared with the lubricated type, its service life is increased by 30%-50%. The track group consists of track shoes, track links, pins, bushings and other components, which are crucial to the wear life of the track group. We use advanced processing technology to ensure precise dimensional tolerances and perfect fit. In addition, after quenching and tempering, induction hardening is performed on the track surface of the chain link, which has excellent wear resistance and fatigue resistance.
MITNIK PARTS can provide customized track sets with PPR structure upon request, with various designs of track shoes.
Typical brands and models: Caterpillar (D11/D10/D9/D8), Komatsu (D475/D375/D355/D275/D155/D85ESS), Hitachi, Daewoo, Doosan, John Deere, Kobelco, Hyundai, Liebherr (PR764/PR765), Sumitomo, Volvo, etc.
