Excavator Seal Kits

Excavators, also known as excavating machinery, are also earthmoving machines that use buckets to dig materials that are higher or lower than the bearing surface and load them into transport vehicles or unload to the stockyard. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator: operating weight (mass), engine power and bucket capacity.

According to the driving mode, the internal combustion-driven excavator, the electric-driven excavator, the walking excavator, the hydraulic excavator, and the mechanical excavator, according to the driving method, are divided into the front excavator, and the backhoe. Excavator, excavator, backhoe excavator

There are two types of common excavators driven by internal combustion engines and electric drives. The electric excavator is mainly used in plateau hypoxia and underground mines and other flammable and explosive places.

According to the size, excavators can be divided into large excavators, medium excavators and small excavators

According to different walking methods, excavators can be divided into crawler excavators and wheel excavators.

According to the different transmission methods, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines.

Divided according to use, excavators can be divided into different categories such as general excavators, mining excavators, marine excavators, special excavators, etc.

Divided by bucket, excavators can be further divided into forward shovel, back shovel, drag shovel and grab shovel. The front shovel excavator is mostly used to dig materials above the ground, and the back shovel is mostly used to dig materials below the ground.

For Hydroline Cylinder seal kits, there are BOOM seal kits cylinder excavator; ARM cylinder seal kits; BUCKET cylinder seal kits,excavator, excavator TRACK ADJUSTER seal kits, CENTER JOINT seal kits, MAIN PUMP seal kits, SWING MOTOR seal kits, TRAVEL MOTOR seal kits, CONTROL VALVE seal kits, PILOT VALVE seal kits AND SO ON.

Different excavators have different hydro line cylinder seal kits, and different cylinder may allocate in the same model of excavators, therefore we kindly advise you to provide the brand; like:sumitomo excavator, samsung excavator, jcb seal,model;cat 305,tata hitachi zaxis 75 part;komatsu cylinder part no.of the machines; the most important one is the part no. Of the part that you want, we will follow the OEM part no. Manual to check for you to fit your machines; how to replace hydraulic cylinder seals,we will guide you to choose suitable one for excavator cylinder repair like jcb hydraulic seal kits as we are hydraulic cylinder seal kits suppliers.

If you do not have part no., you could send the ROD diameter and BORE diameter to double check with the drawing as following.

Power transmission route table

Boom motion transmission route: diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-boom cylinder (hydraulic energy is converted into mechanical energy)-realization of boom motion

Stick movement transmission route: diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-stick cylinder (hydraulic energy is converted into mechanical energy)-to achieve arm movement

Bucket motion transmission route: diesel engine-coupling-hydraulic pump (mechanical energy is converted into hydraulic energy)-distribution valve-bucket cylinder (hydraulic energy is converted into mechanical energy)-achieve bucket motion

For excavators, the brand that we have as following:

The cylinder is a very important item in the hydraulic system, and the repair kits or seal kits play a key role in sealing the oil in the cylinder. Once the oil leakage occurs in the hydraulic cylinder, it will cause the machine to slowly lift and dig weakly. To work efficiency, so for the excavator seal kits,we YD not only provide original quality, but also provide OEM quality and after-sales high-quality products, can ensure that the seal kits and the cylinder match. However, when using  excavator seal kits or repair kits, the following issues should be paid attention to in order to save results.

1. The wear ring on the piston is severely worn, causing friction between the piston and the cylinder liner, and finally straining the cylinder liner, piston and seal.

2. Long-term seal failure, piston seals (mostly U, V, Y-rings, etc.) are aging.

3, the hydraulic oil is dirty, a lot of impurities enter the oil cylinder to wear the piston seal to bad, usually iron filings or other foreign matter.
