Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
This double flange track roller for Komatsu D65 bulldozer is designed to carry the full machine weight while ensuring stable and reliable undercarriage movement. As a heavy-duty bottom roller for bulldozer undercarriage systems, it helps maintain proper track tension, reduces the risk of derailment, and supports smooth operation on uneven or challenging terrain. Their robust design provides enhanced lateral guidance and is especially suitable for dozers operating in tough environments like mining, construction, and forestry.
Premium Materials for Superior Durability
Bulldozer track rollers are typically made of high-strength alloy steel, such as 50MN-45 or 50MN-40, chosen for their excellent hardness, toughness, and fatigue resistance. These materials are well-suited for the conditions of daily bulldozing operations and can withstand the sustained heavy loads and harsh ground contact conditions encountered in mining operations.
After forging, the roller body undergoes controlled heat treatment to achieve a hardened outer surface and a tough inner core. This structure allows the roller to resist wear from continuous contact with the track chain while maintaining its ability to absorb impact without cracking.
Using high-quality steel also ensures dimensional stability under prolonged stress, helping to maintain proper alignment with the track chain and reducing uneven wear on the undercarriage system. This contributes to extended service life and provides more reliable performance in harsh environments such as mining, quarrying, and large-scale earthmoving projects.
