Sealing and guiding ring type K5

Sealing and guiding ring type K5

The sealing and guiding ring type K5 is a precision element designed for hydraulic cylinders and double-acting actuators. It combines guiding and sealing functions, eliminating direct contact between the piston and the cylinder. Made of durable polyurethane and reinforced with cotton fabric coated with NBR, it provides high wear resistance and resistance to hydraulic media. It ensures long system life and low operating friction.

Sealing and guiding assemblies type K

Application:

The K type sealing and guiding assembly is designed for operation in systems with reciprocating motion, such as pistons in hydraulic cylinders or double-acting actuators. 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 improves the durability of working elements, providing high sealing efficiency and low friction.

Implementing K type rings in actuator designs brings a number of design and operational benefits: it simplifies piston construction, reduces the length of cylinder sleeves, limits dead stroke, and facilitates the assembly process. 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 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 piston contact with the cylinder sleeve. This significantly increases the durability of the entire assembly while reducing friction.

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

• Elements labeled 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 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 work stability.

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

All series K 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 like HFA and HFB, and mineral oils.

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