2.  Product Overview


This product is a sealing kit specially designed for Komatsu PC200 and PC120 model hydraulic cylinders. It contains all the necessary seals to ensure your hydraulic cylinder maintains good sealing performance under all operating conditions.

 

3.  Product features


1. High-quality materials: All seals are made of high-quality rubber materials with good wear resistance and pressure resistance.
2. Fully compatible: This product is fully compatible with Komatsu PC200 and PC120 model hydraulic cylinders, no need to worry about size or compatibility issues.
3. Easy to install: All seals are designed to be very easy to install and can be completed without the need for professional technicians.
4. Long life: Due to the use of high-quality materials and sophisticated design, the seals of this product have a long service life.

 

4.  Installation steps


1. Turn off the hydraulic system and ensure that the hydraulic cylinder is at rest.
2. Use appropriate tools to remove the old seal.
3. Install the new seals in the correct order.
4. Make sure all seals are properly installed and tightened.
5. Start the hydraulic system and test to make sure all seals are installed correctly and there are no leaks.

 

5.  Precautions


1. Before installing a new seal, make sure the surface of the hydraulic cylinder is clean and free of any impurities.
2. During installation, please avoid applying excessive pressure to the seal to prevent damage to the seal.
3. Before starting the hydraulic system for testing, make sure all seals are correctly installed and tightened.
4. If any leakage is found, please stop using it immediately and contact a professional for inspection and repair.


6.  Product characteristics

​ 1. Speed = >hammer mechanical movement speed is high, the lubriion oil film may be destroyed, because of not good lubriion and friction heating oil seal, cause life is greatly reduced, we use polyurethane or rubber oil seal at 0.03 m/s ~ 0.8 m/s speed within the scope of work is good
2. The temperature= > low temperature will lower the elasticity of polyurethane or rubber seal, cause leaks, and even the entire oil seal becomes hard and brittle. High temperature can make oil seal volume expansion, soft, cause movement oil seal friction resistance increase rapidly and reduce the compression capacity. Suggest polyurethane or rubber oil seal work continuously - 10 ℃ ~ + 80 ℃ temperature range.
3. Should= > consider when pressure = "high pressure oil seal compression deformation, repellent extrusion ring, groove processing aspect also have special requirements. For get together ammoniac fat sealing the best working pressure in the range of 2.5 ~ 31.5 MPa.
4. Load=>Oil cylinder can bear larger load, seal and bearing ring in a completely different role, suggest polyurethane sealing ring to ensure that the cylinder can bear larger load
