China HITACHI EX25 30 SERIES MINI FINAL DRIVE NEEDLE BEARING 29 X 25 X 13MM | Tonkee®

A needle bearing is a type of roller bearing known for its high load-carrying capacity and compact design.

It is constructed with needle-like cylindrical rollers that have a much smaller diameter compared to traditional ball bearings. This design allows for a larger number of rollers to be accommodated within the bearing, resulting in increased load-bearing capabilities and enhanced durability.

Role in the Final Drive:

The final drive assembly in a mini excavator is responsible for transmitting power from the hydraulic motor to the machine's tracks, enabling it to move forward and backward. The needle bearing with dimensions of 29 x 25 x 13mm is a critical component within the final drive. Its primary role is to provide smooth and frictionless rotation of various parts within the drive, such as gears and shafts.

Load-Bearing Capacity:

The needle bearing's 29 x 25 x 13mm dimensions are carefully engineered to meet the specific load-bearing requirements of the Hitachi EX25/30 series mini excavators. This bearing is designed to withstand the stresses and forces generated during the operation of the final drive, ensuring its longevity and reliability. The high load-carrying capacity of needle bearings is especially beneficial in heavy-duty construction applications.

Compact Design:

Mini excavators like the Hitachi EX25/30 series are known for their compact size and maneuverability.

The needle bearing's small dimensions are well-suited for these machines, allowing it to fit within the confined spaces of the final drive assembly. Its compact design also reduces the overall weight of the final drive, contributing to the machine's efficiency and fuel economy.

Durability and Longevity:

Construction equipment, including mini excavators, operates in challenging and demanding environments. The needle bearing's construction with high-quality materials and precision manufacturing techniques ensures its durability and longevity. This component is designed to withstand heavy loads, vibrations, and extreme temperatures, ensuring the final drive's continued performance throughout its operational life.

Maintenance Considerations:

Proper maintenance of the needle bearing is essential to ensure the reliable performance of the final drive and the overall excavator. Regular inspection and lubrication of the bearing are necessary to prevent premature wear and ensure smooth operation. Timely replacement of the bearing when it reaches the end of its service life is also crucial to prevent costly downtime and potential damage to other components.
