Hot sale HITACHI EX120-1-2-3 ZAXIS ZX120 130-1 SERIES MAIN LIFT RAM BUSHING 71 X 86 X 85MM HEIGHT | Tonkee®

The primary function of the main lift ram bushing is to provide support and stability to the lift ram within the hydraulic system of the excavator.

It serves as a buffer between moving parts, preventing metal-on-metal contact, reducing friction, and ensuring smooth operation. This is essential for maintaining the longevity and efficiency of the hydraulic system, which is responsible for lifting and moving heavy loads.

The dimensions of this bushing, measuring 71 x 86 x 85mm in height, are meticulously engineered to fit precisely within the hydraulic system of the Hitachi EX120-1-2-3 and ZAXIS ZX120-130-1 Series excavators. The accuracy of these dimensions is critical to ensure proper alignment and function within the machinery.

In terms of material, the bushing is typically constructed from high-strength, wear-resistant materials such as bronze or steel.

These materials are chosen for their ability to withstand the extreme pressures and forces that the hydraulic system generates during operation. Additionally, they have excellent self-lubricating properties, reducing the need for frequent maintenance and ensuring a long service life.

The 71 x 86 x 85mm dimensions are carefully designed to provide a snug fit for the lift ram, preventing any unwanted movement or play that could lead to inefficiencies or damage in the hydraulic system. The bushing's 85mm height ensures that it can effectively distribute the load and absorb shocks and vibrations, contributing to the overall stability and safety of the excavator.
