Track link oil seal for excavator     

The oil seal of the crawler chain link of the excavator is an important component of the crawler chain link of the excavator.

The main function is to prevent the lubricating oil from leaking from the outside of the chain link, and at the same time prevent external impurities from entering the inside of the chain link, so as to keep the lubricating oil inside the chain link clean and sufficient.

The oil seal is usually composed of rubber and metal materials, installed at both ends of the chain link, and by compressing the rubber sealing ring, the lubricating oil inside the chain link is isolated from the outside world to prevent leakage.

However, polyurethane elastomer coating ring and protection ring run continuously for 1800 times without wear Other materials, 

such as rice husk roller for rice mill, vibrating sieve plate for coal separator, track for sports field, dynamic oil seal for lifting shovel,  elevator wheel, roller skate wheel, etc.,                                     

also use polyurethane elastomer Track Link Oil Seal as Excavator Cylinder Piston Seals It is necessary to pay attention to improving the friction coefficient of medium and low hardness polyurethane elastic elements and the wear resistance under load. 

This polyurethane elastomer can be added with a small amount of lubricant,

 such as two kinds of aluminum, graphite or silicone oil
