Product Description

Bulldozer lower bottom roller for CAT D7G D7H D7R tractor machine spare parts.Caterpillar D7G Double Flange Track Roller (D7G double side bottom roller) is heavy-duty undercarriage component engineered for CAT D7G dozer, equipped with two integrated guiding flanges on both roller ends to lock track chain firmly and prevent track derailment during sharp turns or uneven rough ground.

Application

Double flange track rollers are installed at front & rear ends of D7G track frame, essential for harsh working environments including stone mines, mountain excavation, mud and gravel construction sites. Cooperates with single flange rollers to balance track stability and rolling resistance for full machine undercarriage protection.

Features

Premium 50Mn/35MnB forged steel body with deep quenching, surface hardness HRC52–58, wear resistance boosted for long service life.

Reliable Duo-Cone oil seal + lifelong internal lubrication, blocks mud, sand and dust infiltration to avoid oil leakage and bearing damage.

Exact OEM dimension matching, plug-and-play installation without modification, fits all original D7G track frame assemblies.

Compact single-flange structure reduces extra friction, lowers overall undercarriage operation cost for general earthmoving projects.

Reinforced forged steel roller body, thicker flange wall, stronger impact resistance for high-load mining, quarry and hill construction working conditions.

Standard Duo-Cone sealing system with permanent grease lubrication, minimal maintenance intervals, stable continuous operation 2000+ working hours.

1:1 OEM size replication, seamless fit for CAT D7G original track undercarriage, compatible with full D7G track link groups.

Dual-flange limiting design disperses lateral side force, reduces abnormal abrasion of track links, idlers and sprockets, cutting long-term parts replacement expenses.
