Material: The needle bearing is typically constructed from high-quality steel or other durable materials to withstand the demanding conditions of construction equipment.

Dimensions: The bearing's size and dimensions are precisely engineered to fit the specific requirements of the hydraulic pump in the ZX120 and ZX130 excavators. This ensures a proper fit and function.

Load Capacity: Needle bearings are chosen for their ability to handle high radial and axial loads, which is essential for a hydraulic pump operating in heavy-duty applications.

Lubrication: Proper lubrication is critical for the longevity of the needle bearing and the hydraulic pump. It may feature provisions for lubrication to minimize friction and wear.

Seals: Some needle bearings come equipped with seals to protect against contaminants like dirt and moisture, which can compromise the bearing's performance and longevity.

Tolerance and Precision: The needle bearing is manufactured to precise tolerances to ensure smooth operation and minimal play, which is vital for the hydraulic pump's performance.

Compatibility: The needle bearing is designed specifically for use in the Hitachi ZX120 and ZX130 excavators, ensuring that it is a direct replacement part.

Durability: The bearing is engineered to withstand the harsh working conditions and loads encountered during excavator operations, contributing to the overall reliability of the machine.

Regular maintenance and inspection of the hydraulic pump and its components, including the needle bearing, are essential to ensure the excavator's continued performance and minimize downtime. When replacing the needle bearing, it's crucial to use genuine or high-quality replacement parts to maintain the hydraulic system's integrity.
