![]() You need reliable, high-quality components for your operation. Materials and specifications are subject to change without notice. ![]() ![]() Note: All comparisons and claims of improved performance made herein are made with respect to the prior Komatsu model unless otherwise specifically stated. Conventional and general construction track rollers available for Komatsu D51, D61 and D65 crawler dozers.Cold weather spec - seal designed to withstand cold temperatures and help maintain elasticity.PLUS (Parallel Link Undercarriage System), single flange and double flange - with increased tread depth and flange height, and internal lubrication.Standard, single flange and double flange - for standard rollers.Expanded flange height promotes effective track alignment and machine stability under varying operating conditions.Material hardness tapers toward the inner bore to help impede brittleness and provide absorption of shock loads.Surface hardness of the roller’s outer shell helps to alleviate wear caused by friction.Reservoir cavities in roller shells and shafts feed lubricant throughout the roller’s interior to help mitigate damage-causing heat.Heavy-duty mounting brackets secure rollers to track frames, allowing the transmission of shock loads throughout the track frame, thereby reducing potential damage.Heat-treated tread and flange areas also contribute to increased strength and longer wear life. Highly polished shafts and bronze bushings help reduce friction and promote extended roller life. Komatsu genuine OEM rollers are constructed of long-wearing, heat-resistant material supported by rubber load rings that keep oil in and dirt out. Skidding Link Assembly: This innovative link structure is engineered for strength and reinforcement that delivers durability, especially in demanding applications such as forestry.Please note: GC link assemblies should not be used in high impact applications such as quarries, forestry and waste applications. Compatible with Komatsu PC160, PC200, PC300 & PC400 excavators, these parts perform well for general construction applications. General Construction (GC): These track link assemblies help control operating and maintenance costs based on application.These assemblies are the basic form of the sealed track, but include grease to help reduce internal pin and bushing wear, promoting extended life of the assembly. Grease Sealed Track (GST): The link assemblies of the GST consist of links, pins, bushings and a “W” seal.Working with our valued customers, we’ve designed three different types of link assemblies for excavators to help you meet the needs of your wide-ranging machine applications. We understand your excavator needs are demanding and varied. Order online Note: All comparisons and claims of improved performance made herein are made with respect to the prior Komatsu model unless otherwise specifically stated. Komatsu now offers conventional and general construction track rollers for PC200, PC220, PC300 and PC400. Cold weather spec, which has a different seal to withstand cold temperatures and maintain elasticity.Standard and single flange with internal lubrication, to offer track alignment during operation.Greater flange height on Komatsu OEM rollers provides maximum track alignment and machine stability under varying operating conditionsĭepending on the application, you can choose from a wide range of track rollers:.To provide absorption of shock loads and avoid brittleness, hardness decreases toward the inner bore surface hardness of the outer shell reduces wear caused by friction.Reservoir cavities in roller shells and shafts feed lubricant throughout the roller’s interior to reduce damage-causing heat.To help keep you up and running, heavy-duty mounting brackets secure rollers to track frames, allowing the transmission of shock loads throughout the track frame.For strength and long wear life, rollers have heat-treated tread and flange areas.To reduce friction and help extend roller life, Komatsu OEM rollers utilize highly polished shafts and bronze bushings.To help keep oil in and dirt out, rollers are constructed of long-wearing, heat-resistant material supported by rubber load rings.To withstand this, several quality steps are taken in the manufacturing of Komatsu genuine OEM rollers. Friction and shock loads transmitted from the track chain create heat within the roller.
