Caterpillar Undercarriage Pins: Precision Connectors for Maximum Durability
Caterpillar undercarriage pins are essential components that link track segments, secure movable joints, and enable smooth, controlled movement across challenging terrain. Each pin is engineered for specific machine models including D6, D8, D9, D10, D11, and more, ensuring a precise fit and robust connection that withstands high impact, twisting forces, and abrasive environments. Available in standard, long, and specialized configurations, these pins are manufactured from high strength, through hardened steel for toughness and wear resistance.
From track pin assemblies to clevis and link pins, Caterpillar designs support both general and heavy duty applications. Advanced options like Positive Pin Retention (PPR) technology use machined grooves and retaining rings to lock pins in place, preventing end play, reducing seal wear, and extending the life of your track chains in demanding conditions. Regular inspection and timely replacement of worn or corroded pins help avoid undercarriage misalignment, uneven wear, and costly downtime.
Propel Parts supplies a comprehensive catalog of high-quality replacement undercarriage pins for Caterpillar equipment. In addition, Propel Parts provides clear compatibility information and fast shipping for quick, reliable repairs.
The internal hardness of our new Pins is thicker to ensure better resistance and longer life. They are manufactured with alloy steel, and are put through an induction hardness procedure that makes the pin more resistant to extreme wear and prevents corrosion. Our pins feature: - Induction harden zone HRC 56 min to depth 1mm - Minimum core hardness HRC 22 to 25 - 0.02 to 0.03mm layer of chrome coating on all surfaces of the pin - Material 42CrMo and 35CrMo
