excavator undercarriage parts

Hitachi excavator undercarriage parts mainly track rollers, sprockets, idlers, carrier rollers, and tracks. Track roller: As the name implies, it plays a supporting role and is located between the lower surface of the left/right beam of the undercarriage and the crawler, depending on the tonnage of the excavator. Usually there are 5-10 on one side. Driving sprockets: plays the role of driving the crawler, fixed on the traveling motor, and transmits the driving force of the traveling motor to the crawler through the gear structure. Usually 1 on each travel motor. Idler wheel: plays the role of guiding the track and is located at the end opposite to the driving force. Usually there are 2 per excavator.

The track adjuster assembly is applied to excavator and bulldozer idler. Track adjuster assembly is made of track adjuster/ track cylinder, idler yoke, tension spring/recoil spring, seals, etc. It is made by forging, heat treatment.

The carrier roller excavator, which is also called carrier roller or top roller, is one part of undercarriage parts for crawler heavy equipments such as excavator, bulldozer, crane, drilling machine etc. Excavator carrier roller excavator is made of roller body, shaft, collars, Bi-metallic Bearings and seal group. It is made by forging, machining, heat treatment, assembly, painting etc. The quality and working life depends on the quality of raw steels, the hardness of rail surface, the depth of hardness layer, the quality of seal group etc. The carrier wheel is located above the X frame, and its function is to maintain the linear motion of the chain rail. If the carrier wheel is damaged, the track chain rail will not be able to maintain a straight line. The carrier wheel is a one-time injection of high-quality oil. It can be replaced with a new one. During the work, try to avoid the rollers being soaked in muddy water for a long time. Usually, keep the X-frame inclined platform clean, and don't let too much dirt and gravel accumulate to hinder the rotation of the rollers.

Idler excavator use low alloyed boron steels with certified hardenability based on Berco specification (for fabricated versions).  Low alloyed cast steel (cast version).  Heavy duty ring-rolled tread rims (for fabricated versions).  Induction hardened tread diameter.  High tread surface hardness (HRC > 50) for reduced wear and longer life.  Tempered to resist cracking and chipping of idler excavator.  Precise design and manufacturing for proper fit.  Easy resurfacing.  Idler excavator can be supplied alone or fully assembled with brackets, adjuster and tension device.

Main Features of kubota track rollers:   1.Single and double-edge road wheel suits for Kubota excavating machine and special machinery ranging 3 to 50 tons. 2.Double conical sealing and lifelong lubrication design enable the road wheel to have longer service life and perfect performance in any circumstances. 3.The shell of kubota track rollers made by hot forging treatment obtains superior structure of internal materials and fiber. 4.Differential quenching or feed-through quenching heat treatment is effective in crack resistance.

The idler pc200, which is also called idler group, idler assy, front idler or idler wheel, is one part of undercarriage parts for crawler heavy equipments such as excavator, bulldozer, crane, drilling machine etc. The idler pc200 is made of idler shell, shaft, brackets, Bi-metallic Bearings and seal group. It is made by casting or forging, machining, heat treatment, assembly, painting etc. The quality and working life depends on the quality of raw steels, the hardness of rail surface, the depth of hardness layer, the quality of seal group etc. The misalignment of the idler excavator has a serious impact on other parts of the walking mechanism, so we need to adjust the gap between the guide wheel guide plate and the track frame to achieve the purpose of extending the life of the walking mechanism. When adjusting the gap, pay attention to use the gasket between the guide plate and the bearing to correct it. If the gap is large, remove the gasket; if the gap is small, add a gasket.
