Back to Undercarriage Track Chain Components

Individual components work together to provide assemblies with Excellent Durability and Long Service Life in tough working environments.

Pins & Bushings

ITR Pins & Bushings are designed, manufactured, and dimensionally matched to link bores providing excellent pin retention and Track Joint Stability. Better joint reliability helps eliminate seal / joint problems and results in extended wear and performance.

ITR Pins resist bending and breakage by using selected materials and special heat treating processes with differential spray quenching. ITR Bushings have high surface and core hardness that provides excellent strength and wear characteristics by utilizing Through Hardening or Through Hardening plus Induction Hardening processes depending on application.

Links

Forged Boron Steel links provide greater strength, stability and wear resistance. Sophisticated heat-treating processes give ITR chain links excellent surface hardness, deep hardening depth and strong core hardness for durability and strength.

High strength materials in conjunction with heavy cross sections are designed to maximize pin to link contact area…Large pin to rail contact helps eliminate “Pin Walking” and premature failure in tough working environments. ITR link designs result in a link profiles that resist link twisting and deformation.

ITR track chains use the preferred Split Master Link designs, produced using state of the art machining technology for proper mating of the split link halves.

Sealing

To keep lubricants in and abrasives out, ITR chain designs utilize specially engineered Rigid Polyurethane Seal designs. These durable long lasting seals combine high wear resistance and lubricant protection to extend pin and bushing life.

Sealed & Lubricated joints on lubricated tracks are designed for the life of the chain. Advanced computer controlled assembly insures proper seal installation and guarantee each joint is filled with the correct amount of lubricant. Each lubricated joint is pressure tested during the manufacturing process. Wet joint Integrity is covered by ITR’s Wet Turn Assurance Warranty.
