OEM HITACHI EX100 120-1 TRAVEL DEVICE FINAL DRIVE ROLLER NEEDLE BEARING (OEM HI 4177007 FA 71402036) | Tonkee®

The travel device final drive roller needle bearing for the Hitachi EX100-1 and EX120-1 excavators is a precision-engineered component designed to withstand the demanding conditions of heavy-duty construction work.

This bearing is constructed using high-quality materials to ensure durability and longevity. Typically, needle roller bearings are made from hardened steel, known for its high tensile strength and resistance to wear and tear. These materials are chosen to endure the immense loads and stresses that these excavators encounter during operation.

Function and Importance:

The primary function of the travel device final drive roller needle bearing is to facilitate the smooth rotation of the final drive, which is a crucial part of the excavator's undercarriage system. The final drive is responsible for propelling the excavator and moving it in different directions. It transfers power from the engine to the tracks or wheels, allowing the machine to traverse various terrains and perform excavation tasks effectively.

The needle bearing plays a pivotal role in reducing friction and ensuring efficient power transmission within the final drive. Its design incorporates numerous cylindrical rollers that provide a large contact area, minimizing friction and distributing the load evenly. This design feature is essential for preventing premature wear and tear, thereby extending the service life of the final drive and the entire excavator.

Performance and Reliability:

The Hitachi OEM HI 4177007 or FA 71402036 needle bearing is engineered to meet the stringent performance requirements of the EX100-1 and EX120-1 excavators.

It undergoes rigorous quality control and testing to ensure its reliability in extreme conditions. The precision manufacturing processes employed in its production result in tight tolerances, which are critical for maintaining the bearing's performance under heavy loads and continuous operation.

One of the key benefits of this needle bearing is its ability to operate smoothly and efficiently, even in harsh environments where dust, debris, and contaminants are prevalent. Its sealed design helps prevent the intrusion of foreign particles, further enhancing its durability and performance.

Maintenance and Replacement:

Like all mechanical components, the travel device final drive roller needle bearing requires regular maintenance to ensure optimal performance. Lubrication is essential to minimize friction and heat generation, which can lead to premature failure. Manufacturers often provide maintenance schedules and guidelines to help equipment operators and technicians properly care for and inspect the bearing.
