excavator cylinder seal kits

Hydraulic systems are widely used in various machinery and equipment, functioning on the principle of fluid power to perform heavy tasks efficiently. Among the critical components in these systems are hydraulic cylinders, which are responsible for converting hydraulic energy into linear motion. However, over time, the seals in these cylinders can wear out due to factors like pressure cycles, temperature fluctuations, and contamination. When this happens, replacing the hydraulic cylinder seal kit becomes essential to ensure the system operates smoothly and reliably.

Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.

Dust Seal vs Oil Seal Understanding the Key Differences and Applications

1. O-Rings These are the most common type of seal, consisting of a circular ring made from elastomeric materials. O-rings are versatile and can be used in various applications due to their simple design and effective sealing capabilities.

Leather 
Recommended for abrasive applications 
Good running properties, due to the impregnated seal lip 
Can be used on shafts which have a surface roughness outside the range for rubber seals 
Not suitable for water

These are comparable to type R and RST, except the outer case does not have a metal reinforcement ring. To compensate, the outside is not made of normal rubber, but a hard, heavy-duty rubber fabric. The advantage is that these types can be made in a split version. They are almost always produced to order, and made of NBR or FKM.
