Sealing and guiding ring type K3

Sealing and guiding ring type K3

The sealing and guiding ring type K3 is a component dedicated to hydraulic cylinders operating in demanding operating conditions. Constructed from a mix of NBR and stiffening material, it provides both sealing and guiding functions for the piston or plunger. It is characterized by high resistance to wear, pressures, and HFA and HFB hydraulic fluids. It minimizes friction and protects the cylinder from direct contact with the piston, increasing the system's durability.

Sealing and Guiding Assemblies type K

Application:

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

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

Construction and Technical Parameters:

The K type sealing and guiding ring is a modern component of hydraulic power systems designed for reciprocating motion - mainly in hydraulic cylinders and double-acting actuators. 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.

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

• Elements marked KP (e.g., K2, K5) are made of high-grade 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, known for its resistance to mineral oils and hydraulic fluids.

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

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

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

All K series variants have been optimized to operate 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 construction of K type rings allows for simplifying piston construction, shortening cylinder sleeves, and reducing the dead 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.
