Heavy Duty Bogie Pins for Caterpillar® (CAT) Mining Dozers
Introduction For mining and heavy construction, the undercarriage of your Caterpillar® dozer takes the hardest hit. Our aftermarket Bogie Pins are engineered to keep your CAT D10 and D11 machines moving. We specialize in providing both Standard and Heavy Duty (HD) versions designed to survive the most abrasive and high-impact environments.
The Heavy Duty (HD) Advantage Unlike standard components, our Heavy Duty Bogie Pins are crafted for extreme longevity:
Special Alloy Steel: Manufactured from a custom steel blend designed for maximum core strength.
Specialized Heat Treatment: Our HD pins undergo a deep-hardening process that creates a wear-resistant surface while maintaining a tough, ductile core to prevent snapping under load.
Severe Application Ready: Ideal for machines operating in rock quarries, mines, and abrasive soil conditions where standard pins fail prematurely.

Q: When should I choose Heavy Duty (HD) bogie pins over Standard ones?
A: Heavy Duty pins (like 7T9307 HD) are recommended for extreme applications involving high impact or abrasive terrain (mining). They have specialized heat treatment to resist wear longer than standard pins.
