MARAT offers a wide range of standard industrial seals and customized products for your individual needs.
Seals have a critical impact on machine performance as they prevent contaminants from entering into its immediate environment. Service life and overall reliability of seal can make significant difference to the effective performance of your equipment. MARAT can support the key aspects of the sealing system through its knowledge of bearings, sealing solutions, lubrication and diagnostics.
MARAT introduced its own brand of seals that are manufactured under the name of “GM Seal”. We offer a wide range of seals for a variety of applications and maintenance and repair works . “GM Seal” seals are used in industries such as machine building, petrochemicals, mining, metallurgy, energy, automotive, agriculture and many others.
We offer the following major types of seals and sealing solutions:
- Dynamic seals – shaft seal (simmering), V-rings, radial & axial seals, and sliding seals.
- Static Seals – O-rings, X-rings, back-up rings, seals for pipe and screw connections, and gaskets.
- Hydraulic Seals – piston seals, rod and buffer seals, wiper seals, guide rings and guide strips, and O-rings and back-up rings.
MARAT also offers customized products to better meet individual and specific needs of our customers.Click here and check our commercial offer for seals
Seals in contact with sliding surfaces
The seals in contact with sliding surfaces are also called dynamic seals. They are designed for sealing the space between surfaces with definite relative motion (rotating or oscillating motion). This type of seals includes: radial shaft seals, axial shaft seals (V-rings), and packing and piston seal rings. These seals are manufactured in metric and inch standards and are commonly made of NBR or FPM material. This group also includes mechanical face seals (bearing seals), which are designed to operate in harsh environments and are normally made of elastomer bearing steel or cast iron and elastomer. Dynamic sealing is more difficult than static sealing as it requires more meticulous selection of design and material execution. Dynamic seals commonly serve the purpose of retaining lubricant, excluding contaminants and withstanding differential pressures.
Seals in contact with stationary surfaces
The seals in contact with stationary surfaces are commonly referred to as static seals. Typical examples of static seals are: O-rings and gaskets. A static seal is located in a groove and sees little or no relative motion between the mating surfaces. These seals are available in standard metric and inch sizes as well as in a wide variety of sealing material and can be safely used in almost every industry.
Seals for reciprocating motion
The seals for reciprocating motion are designed to seal the space between the elements moving to-and-fro relative to each other. This group includes seals for hydraulic and pneumatic actuators such as piston and rod sealing tapes and guide rings. These seals are made of various materials depending on the use and application.
