Each type of seal has unique properties and is designed to operate under different conditions. We offer O-rings made from various materials, including Viton® FKM FPM, providing resistance to a variety of chemical and temperature factors.


Seal Materials and Compositions

Choosing the right material is key to the durability and effectiveness of the seal. The choice depends on the application specifics and machine operating parameters. Some of the materials we use for seals are presented in the table below:

Material Properties
EPDM, NBR, Silicone, Teflon®, Viton® Varied resistance to temperature, chemicals, abrasion, and other environmental factors

We also offer seals made from other rubber compounds.


What is the basis of seal reliability?

A reliable seal is fundamental to the proper operation of every machine and device. The quality of the seal directly impacts the lifespan of components, minimizing the risk of failures and downtime. Regular replacement and inspection of seals, including O-rings and oil seals, is essential to maintain high-quality machine operation, especially in industrial settings. We offer only top-quality products.

Hydraulic Seals

What are hydraulic seals and where are they used?

Hydraulic seals are critical elements in hydraulic systems designed to seal connections and prevent leaks of hydraulic fluids such as oils. They have wide applications in various industries, including manufacturing, construction, and heavy machinery. Good hydraulic seals ensure efficient machine operation and minimize failure risks.

Power Rubber’s hydraulic seals are characterized by high quality and durability. They are made from premium materials that provide resistance to high pressure, temperatures, and aggressive fluids. Our assortment includes seals for hydraulic cylinders, pumps, and other hydraulic system components. Selecting the right seal is essential to ensure machine reliability and efficiency, and seal quality is our priority.


Hydraulic Seals in Industry

In industry, hydraulic seals play a vital role. They are necessary for the proper functioning of machines and devices used in production, transportation, and other technological processes. Reliable seals help avoid downtime and costly failures, increasing efficiency and profitability. Our hydraulic seal offer in Kraków is aimed at demanding customers seeking the highest quality products.


Bearings in Kraków

Types of Bearings

There is a wide range of bearings available on the market, including ball bearings, roller bearings, tapered bearings, and many more. They are designed for various industrial and structural applications. Choosing the right bearing depends on machine operating parameters such as load, rotational speed, and temperature. Our store supplies both standard and specialized bearing seals.


Bearing Seals – Why Are They Important?

Bearing seals are crucial for their proper functioning and durability. Their primary task is to protect the bearing from contaminants like dust, dirt, and moisture, which can cause premature wear. Good seals also prevent lubricant leaks, which is necessary to ensure optimal lubrication and reduce friction.


O-rings in Kraków – Circular Sealing Rings

What are O-rings and what are they used for?

O-rings, also known as O-ring seals, are popular technical seals with a circular cross-section. They are used for sealing joints in machines and devices across various industries, in both static and dynamic applications. Their simplicity and versatility make them widely used in industry. Our Kraków offer includes a broad assortment of O-rings tailored to diverse needs.


Use of O-rings in Hydraulics

In hydraulics, O-rings play a key role in sealing hydraulic cylinders, pumps, and other components. Their resistance to high pressures and aggressive hydraulic fluids makes them indispensable in such applications. Hydraulic seals based on O-rings provide reliability and minimize failure risks.

We offer high-quality rubber O-rings for sale in Kraków, Warsaw, Poznań, Wrocław, Gdańsk, Katowice, Łódź, Szczecin, Lublin, and many other cities throughout Poland. Our O-rings come in various sizes and materials suitable for different industrial and technical applications. We supply both wholesale and retail, ensuring fast and secure delivery within Poland and abroad.

Gaskets and Oil Seals (Simmerings)

Differences between gaskets and oil seals

Gaskets and oil seals (simmerings) are two different types of technical seals, though both serve sealing functions. Gaskets usually seal static joints between two surfaces, whereas oil seals are designed for rotary motion applications, e.g., around shafts. Oil seals have a special design to ensure effective sealing while minimizing friction. We offer both types of seals.


How to Choose the Right Gasket?

Choosing the right gasket depends on factors such as the type of sealed medium, temperature, and pressure. Selecting the proper gasket is key to reliable sealing and avoiding machine failures. Good technical sealing is fundamental. The material the gasket is made from, e.g., EPDM, NBR, HNBR, PTFE, also affects the choice.


Simmerings – Application in Hydraulic Systems

Oil seals are widely used in hydraulics, especially for sealing shafts of pumps and cylinders. Their design ensures effective sealing even in challenging working conditions. It is important to select oil seals made from materials resistant to hydraulic fluids and high temperatures.
