Undercarriages Systems

The patented fifth link is what sets torsion suspension apart from other undercarriages. This additional fifth link acts like an independent suspension system, allowing the undercarriage to move with the terrain beneath it. It’s a smarter, smoother way to move.

The 5-Link torsion suspension absorbs the natural vibration of steel undercarriages, creating a smoother ride and reducing wear on both the machine and operator over time. It’s a simple, smart design that turns rough ground into a more comfortable, productive experience. 

The 5-Link system is engineered to maximize ground contact, which reduces ground pressure and improves traction in soft or muddy conditions, enhancing ride quality across all terrains.

The elevated sprocket in Bobcat’s 5-Link torsion suspension helps reduce wear and makes undercarriage cleanout easier. For those working in muddy, sandy, or debris-heavy environments, it’s a simple design change that makes a major difference in uptime and undercarriage health.

Key components in the 5-Link system, including inner bars, arm and spindles are heat-treated for maximum strength and durability.

Exclusive to the T86 compact track loader, the triple-flange rear idler delivers superior track retention and durability. The added third flange helps keep the track engaged, even under partial de-tracking conditions—allowing you to travel safely back to home base for service. It enhances alignment security, extends idler life, and provides an extra layer of protection against unexpected downtime.

Built from heavy-duty forged steel, dual-flange idlers help keep the track aligned and maintain consistent ground contact for a smoother ride. By reducing the chance of de-tracking, they extend the life of both the track and the entire undercarriage system—keeping your operation steady and your uptime protected.

In Bobcat’s solid undercarriage, the drive motor and hydraulic hoses are routed and protected within the undercarriage. This layout helps prevent damage from debris, snags and impacts that are common on harsh worksites. By reducing exposure, we help extend the life of critical components, reduce the frequency of maintenance issues, and boost uptime where it matters most.

Bobcat undercarriages are built to make maintenance easier and extend component life. The sloped-side design helps prevent debris buildup during operation, while raised cutouts provide convenient access for quick cleaning. Together, these features reduce the chances of de-tracking due to debris buildup, simplify upkeep, and keep you focused on the work—not the cleanup.

Wide rollers give you more surface area in contact with the track—providing a smoother ride for the operator and less wear and tear on your machine over time. Permanently lubricated and engineered for endurance, Bobcat wide rollers are built for long hours and tough terrain.

Maintaining proper track tension is crucial for performance—but that doesn’t mean it should be a hassle. The solid undercarriage features an easy-to-access tensioning system, letting you adjust quickly and get back to work.
