5. PPR Track Link Structure
Positive Pin Retention Track features an exclusive design that resists link end play, increases sealability, and maximizes track life, specially machined links and pins that allow for the use of a metal retaining ring. This ring is pressed into the groove between the pin and link, locking the joint to a predetermined factory end-play specification. This design is recommended for mining, heavy construction, demolition, and waste disposal applications conditions that generate high loading and impact, twist the track chain, and cause end play. Machines equipped with wider shoes, extreme service shoes, or super extreme service shoes should also consider PPR Track.
