China HITACHI EX200-5 FINAL DRIVE TRAVEL DEVICE NEEDLE ROLLER BEARING PLANETARY 3 (OEM HI 4317122) | Tonkee®

The choice of needle roller bearings for this application is significant due to their high load-carrying capacity and efficient performance under heavy loads and high-speed conditions.

These bearings consist of cylindrical rollers that are much thinner in diameter compared to their length, resembling needles, hence the name "needle roller bearings." This design allows them to accommodate both radial and axial loads efficiently.

The OEM part number HI 4317122 signifies that this needle roller bearing is an original component manufactured by Hitachi specifically for the EX200-5 excavator model. OEM parts are designed to meet the manufacturer's strict quality and performance standards, ensuring compatibility and reliability with the machine

Material: The bearing is typically constructed from high-quality materials, such as hardened steel, to withstand the harsh operating conditions of an excavator.

Dimensions: Needle roller bearings come in various sizes, but the exact dimensions for the HI 4317122 bearing would need to be obtained from the manufacturer's documentation to ensure proper fit and function.

Load Capacity: These bearings are designed to handle both radial and axial loads, which are common in heavy equipment applications like excavators.

Precision: Precision manufacturing is essential to ensure smooth and reliable operation. The needle rollers and bearing surfaces must be carefully machined to minimize friction and wear.

Sealing: Depending on the application and design, the bearing may feature sealing to protect against contamination and moisture, which can extend its service life.

Compatibility: As an OEM part, the HI 4317122 bearing is specifically designed to fit and function with the Hitachi EX200-5 excavator. Using OEM parts ensures compatibility and reliability.

Maintenance: Like all mechanical components, proper maintenance is essential to prolong the life of the needle roller bearing. Regular lubrication and inspection are critical to prevent premature wear and failure.
