Undercarriage Terminology

Special heat treat processes give Cat links consistent surface hardness, superior hardening depth, and strong core hardness. This results in excellent wear resistence, strength, and durability for unmatched sealability and long life.


Cat rollers are through hardened for long wear life, unmatched structural support, and resistance to deformation. Cat's Duo-Cone seals help ensure lifetime lubrication to extend life, permit roller reshelling, and lower your costs.


High surface hardness and excellent hardened depth and core hardness mean Cat segments provide long wear life, resistance to bending and breakage, and maximum hardware retention. The bolt-on design reduces replacement time.


Pins & Bushings
Cat pins and bushings are dimensionally matched to the links and manufactured to provide excellent track joint integrity. This design helps ensure maximum sealability. High surface and core hardness translate into increased strength and wear resistence.


To keep abrasives out and oil in, the Caterpillar rigid seal design combines high wear reistance and load protection. The result is a "wet" joint at turn time, which extends bushing life and lowers your cost


Special heat treat processes help ensure proper hardness levels, providing wear resistance. Duo-Cone seals help ensure lifetime lubrication. eliminating idler maintenance and lowering operating costs.


Track Shoes
Caterpillar track shoes are furnace hardened and tempered for strength and resistance to bending and breakage. We offer a variety of track shoe options to meet the requirements of your work environment.
