The design of Cat 349D bushings reflects Caterpillar's focus on robustness and serviceability:
Material and Hardening Process:
They are typically manufactured from high-strength, medium-carbon steel.
The key design feature is a through-hardened or case-hardened surface. This process creates an extremely hard, wear-resistant outer layer while maintaining a tough, ductile core to absorb shock loads and prevent cracking or brinelling.
This 462-2003 bushing is used for 349D excavator.
