RING

Thrust rings are used to help protect the sealing system. Attributes: Cat® Sealed and Lubricated Track (SALT) seals lubricant into your undercarriage system and keeps abrasives out. It eliminates internal pin and bushing wear to reduce maintenance costs and downtime, while increasing service life and serviceability. SALT offers a universal undercarriage configuration for a wide range of underfoot conditions when coupled with a track design that matches your machine and operating environment.
