7G9709 Sleeve Bearing for Caterpillar CAT Dozer

Sleeve Bearing 7G-9709 for Caterpillar Bulldozer The 7G-9709 sleeve bearing (also classified as a track roller bushing) is a high-strength undercarriage component engineered specifically for heavy track-type tractors and earthmoving machinery. Positioned within the lower roller assemblies, this precision-machined sleeve minimizes frictional wear between the rotating roller shell and the stationary shaft. Built to survive extreme radial loads, continuous structural shock, and severe multi-directional stress, this premium aftermarket bearing guarantees smooth undercarriage rotation and maintains track alignment in punishing mining and construction applications. Product Specifications Precision-manufactured to strict dimensional tolerances with specialized internal oil channels that facilitate continuous lubrication and prevent heat buildup under load. Part Number: 7G-9709 Alternative Format: 7G9709 Product Class: Heavy Machinery Undercarriage Wear Parts Component Type: Sleeve Bearing / Flanged Track Roller Bushing Material Composition: Heavy-Duty Bronze-Copper Alloy / Bimetal Steel Backing Cross-Reference & System Placement This industrial sleeve bearing matches original equipment manufacturing standards and integrates into the primary chassis lower frame assembly: Interchangeable References: 7G-9709, 7G9709 System Association: Lower Track Roller Group / Single and Double Flange Roller Assembly Primary Function: Provides a low-friction, high-load bearing surface for the roller shaft to distribute machine weight evenly across the track chains. Application and Machinery Compatibility Accurately dimensioned to deliver a secure hydraulic press-fit for the following Caterpillar (CAT) crawler dozer and track-type tractor series: Compatible Caterpillar Bulldozer Models D7G Series / D7G Series II D7H Series / D7H XR / D7H LGP D7R Series / D7R XR / D7R LGP D8N Series Associated Mechanical Assemblies Standard undercarriage lower roller groups Heavy-Duty (HD) track roller assemblies Installation and Undercarriage Maintenance Notes Technical Recommendation: Excessive side-play in the track rollers, abnormal track chain alignment, or oil weeping from the duo-cone floating seals point to advanced internal sleeve wear. When rebuilding track roller groups using the 7G-9709 sleeve bearing, always employ a specialized hydraulic press with an appropriately sized alignment mandrel to avoid scoring the soft inner bronze bore. Thoroughly inspect the roller shaft for grooving or out-of-round wear prior to press-fitting, and renew the floating seal assembly to lock in the internal oil reservoir. Related Part Numbers NO P.N.
