Sealing and guiding ring type K6

Sealing and guiding ring type K6

The sealing and guiding ring type K6 is a modern solution designed for pistons in hydraulic cylinders. By using a technical fabric coated with NBR rubber and polyurethane, it provides optimal guiding and reliable sealing in dynamic conditions. It reduces friction and wear, extending the system's lifespan. Recommended for use in hydraulic systems requiring precision and durability.

Sealing and guiding assemblies type K

Application:

The sealing and guiding assembly type K is intended for use 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 the working elements, providing high sealing efficiency and low friction.

Implementing K rings in the design of cylinders brings a variety 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 and guiding ring type K is a modern component of hydraulic 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 90° IRHD hardness, ensuring excellent wear resistance.

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

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

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

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

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

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