7P-7428 88 mm Long Idler Link Pin
Cat® idler link pins connect the idler, maintaining track tension, alignment and stability for efficient operation
Description
Cat machine linkage pins support rotation between the frame, linkages and work tools. They are used anywhere rotation must occur between two structures. Genuine Cat pins and sleeve bearings are specially designed to work together as a system to deliver the performance you expect. Caterpillar design engineers match each part with the right combination of size, material, heat treatment, surface finish and manufacturing process so it works effectively and wears in sync with all other adjacent and dependent parts.
Features
Cat linkage pins are machined from premium steel bar and hardened for exceptional strength and wear life. They work as part of the pin joint system on specific Cat machines and are tested and proven in the world's toughest applications. Surface hardness, finish and plating are carefully selected for outstanding performance with sleeve bearings. They lowers overall cost while delivering outstanding strength and fatigue life, superior wear resistance and excellent pin wear protection, even under high-load conditions.
Applications
Cat hardened linkage pins are designed for situations that require superior load-carrying capacity, strength and wear resistance, extending pin joint life. Cat linkage pins are the first choice for maximizing performance in demanding applications. They are designed to work with mating sleeve bearings.
