| Steel tracks | |
| Komatsu undercarriage is developed and manufactured according to high quality requirements as defined in the Komatsu Engineering standards. This is what makes us better than the most of our competitors: | |
| Sprockets: | |
| Komatsu offers sprockets in cast, single-piece or segmented styles. Both styles feature deep introduction hardened teeth made of silicone manganese steel for superior resistance to impact, heavy loads and wear. They are also reinforced with additional metal at stress areas. Precision manufacturing and machining techniques insure perfect sprocket fit, alignment and interchangeability. | |
| Track shoes: | |
| With four styles to choose from – single grouser, triple grouser, offset and swamp shoe – there is an appropriate style designed for your particular working condition. Each shoe style is manufactured to specific steel specifications then heat-treated for maximum wear resistance. | |
| Track links: | |
| Komatsu offers both , dry and lubricated track systems. Each features high-strength tempered manganese steel links, heat treated to the optimum degree and depth of hardness for extraordinary wear resistance. Both styles offer Komatsu's split master link design for easy servicing. The advantages of our lubricated track system are multiple. First, it seals in lubrication while sealing out contaminants. Secondly, it virtually eliminates internal pin and bushing wear as well as elongation of link pitch, which reduces sprocket tooth tip wear. | |
| Idlers: | |
| Using sophisticated CAD system, Komatsu designs and manufactures its idlers to demanding specifications for smooth operating performance and extended wear life. Rail surface hardness of 52 to 60 HrC and case depth harness of 3 to 5 mm are typical, depending on the size of the idler. Komatsu idlers come complete with brackets and are factory lubricated and sealed. | |
| Rollers: | |
| Komatsu rollers feature two-piece drop forged, deep heat-treated roller shelles with a rail surface hardness of 53 to 60 HrC and core hardness of 40 HrC where contact is made with hubs and bushings. Collars and hubs are made of cast iron and machined to the tightest specifications. Bushings have a steel outer shell to resist deformities and an antifriction inner brass liner. Shafts are induction hardened to 60 HrC and precision machined. They offer superior wear resistance and strength, generous lubrication capacity and floating seals to keep oil in and dirt out. | |
| Pins and bushings: | |
| Komatsu link pins and bushing are made of special composite steels which are surface, core and case deep heat treated for exceptional strength and wear resistance. Precision machining insures pins and bushings will perfectly match-up with individual links. | |
