Track Link Oil Seal Excavator

SGU track chain oil seal (link oil seal)

Operating conditions:

Material: Polyurethane

Temperature: -35~100 ℃

Design Notes:

Clothing belt is an important component of walking construction machinery, widely used in construction, ports, mining and other occasions, facing harsh working conditions such as sand and sewage. In these harsh working conditions, the service life of the track depends on the sealing performance of the track chain pin.

In addition to sealing, waterproof, dustproof and other functions, as well as the compatibility of materials and grease, we also consider the situation of turning and unbalanced terrain in the design. The unique M-shaped design can fill gaps like a spring and maintain good sealing. feature

Excellent wear resistance

Low permanent compression deformation

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
