Sealing and guiding ring type K2

Sealing-guiding ring type K2

The sealing-guiding ring type K2 is a precision component used in hydraulic cylinders, combining the functions of sealing and guiding the piston. Made of high-quality polyurethane and nitrile NBR, it ensures excellent resistance to wear, pressure, and hydraulic fluids such as HFA and HFB. It is characterized by high dimensional stability and low friction coefficient, which extends the life of hydraulic systems and increases their reliability. Ideal for industrial applications.

Sealing-guiding assemblies type K

Application:

The sealing-guiding assembly type K is designed for use in systems with reciprocating motion, such as pistons in hydraulic cylinders or double-acting cylinders. Its modern design is based on the elimination of direct contact between the piston and the cylinder by using guiding rings made of durable synthetic materials. This solution significantly increases the durability of the working components, providing high sealing efficiency and low friction.

Implementing type K rings in the construction of cylinders brings a range of design and operational benefits: it simplifies piston construction, reduces the length of cylinder sleeves, limits dead-stroke, and facilitates the assembly process. This is an optimal solution for applications requiring reliable sealing and efficient piston guidance while maintaining high system durability.

Construction and technical parameters:

The sealing-guiding ring type K is a modern component of hydraulic power systems, designed for reciprocating motion - mainly in hydraulic cylinders and double-acting cylinders. Its key advantage is the integrated guiding and sealing function, which eliminates direct contact between the piston and the cylinder sleeve. This significantly increases the durability of the entire assembly, while reducing friction.

Type K rings are available in various design and material variants, tailored to different working conditions:

• Components marked KP (e.g., K2, K5) are made of high-quality urethane rubber (AU) with a hardness of 90° IRHD, ensuring excellent wear resistance.

• Versions KG (e.g., K, K2) are produced from nitrile rubber (NBR) with a hardness of 82° IRHD, characterized by resistance to mineral oils and hydraulic fluids.

• KF rings are manufactured from polyacetal - a high crystallinity synthetic material providing rigidity and chemical resistance.

• Type KT (e.g., K, K6) is based on a technical fabric impregnated with NBR rubber, enhancing the structure and providing additional operational stability.

• Variants KG (e.g., K3, K5) are also available in injectable polyurethane (UT) with a hardness of 90-95° IRHD.

All series K variants have been optimized to work at speeds up to 0.5 m/s and are compatible with various media - including hydraulic oils, non-flammable fluids such as HFA and HFB, and mineral oils.

The design of type K rings allows for simplifying piston construction, shortening cylinder sleeves, and reducing dead-stroke length of the actuator, resulting in lower costs and more efficient operation of equipment. This solution is dedicated to demanding hydraulic systems where reliability, durability, and optimal sealing are crucial.
