Buy HITACHI EX100 120-1 TRAVEL DEVICE FINAL DRIVE NEEDLE ROLLER BEARING (OEM HI 4183108) | Tonkee®

The needle roller bearing is a type of rolling element bearing designed specifically for applications where high radial loads and limited available space are common challenges.

It consists of cylindrical rollers that are much thinner in diameter compared to their length. This design allows for a high load-carrying capacity while maintaining a compact and lightweight profile, making it ideal for use in construction equipment like the Hitachi EX100-1 and EX120-1.

The primary purpose of the needle roller bearing within the travel device is to facilitate the rotation of various components, including the final drive assembly. The final drive assembly is a critical part of the machinery's power transmission system, responsible for converting the engine's power into rotational force that drives the machine's tracks or wheels.

Material: The needle roller bearing is typically made from high-quality steel, ensuring durability and resistance to wear and tear in the demanding construction environment.

Precision Engineering: This component is manufactured to precise tolerances, ensuring a snug fit and minimal friction, which is essential for efficient power transmission and extended service life.

Load Capacity: The needle roller bearing is engineered to handle significant radial loads, making it suitable for applications where heavy equipment and dynamic forces are involved.

Lubrication: Proper lubrication is crucial to reduce friction and prevent premature wear of the bearing. Adequate lubrication also helps dissipate heat generated during operation.

Sealing: Many needle roller bearings, including OEM HI 4183108, come equipped with seals or shields to protect against contamination from dust, dirt, and moisture. This enhances the bearing's reliability and longevity.

Compatibility: The Hitachi EX100-1 and EX120-1 travel device final drive needle roller bearing is specifically designed to fit these models, ensuring a seamless replacement process.

Maintenance: Regular inspection and maintenance of the needle roller bearing are essential to prevent breakdowns and extend the overall lifespan of the construction equipment.
