China HITACHI ZAXIS ZX350 SERIES SLEW BOX SEAL 290 X 250 X 21MM | Tonkee®

First and foremost, the dimensions of the seal are 290 x 250 x 21mm.

These measurements are crucial because they determine how the seal fits within the slew box assembly. The 290mm and 250mm dimensions relate to the seal's outer diameter and inner diameter, respectively. The 21mm thickness is significant as it impacts the seal's ability to prevent the ingress of contaminants, maintain lubrication, and withstand the mechanical stresses and pressures it will encounter during operation.

The material composition of the seal is another vital aspect of its specification. Typically, seals in heavy machinery like excavators are made from high-quality rubber or elastomeric materials. These materials are chosen for their ability to withstand extreme temperatures, resist wear and tear, and maintain their sealing properties over an extended period. However, the specific material used for this seal would need to be confirmed based on the manufacturer's specifications.

Seals in heavy equipment like the Hitachi Zaxis ZX350 Series are designed to perform several critical functions:

Contaminant Exclusion: The seal prevents dust, dirt, water, and other contaminants from entering the slew box. This is crucial to protect sensitive internal components such as gears and bearings from damage or premature wear.

Lubricant Retention: The seal helps retain lubricating oil or grease within the slew box, ensuring that critical moving parts are properly lubricated. Adequate lubrication reduces friction, heat, and wear, extending the lifespan of components.

Pressure and Load Resistance: As part of the slew box assembly, the seal must withstand significant mechanical stresses and pressures.

It prevents hydraulic fluid leakage, helping to maintain the integrity of the hydraulic system.

Temperature Resistance: Heavy machinery operates in a wide range of temperatures, from extreme cold to intense heat. The seal material must be capable of maintaining its sealing properties under these varying conditions.

Longevity: Given the cost and complexity of excavators like the Hitachi Zaxis ZX350 Series, it is essential that components such as seals have a long service life to minimize downtime and maintenance costs.
