Product Description

KZT is specifically designed for moving pistons and rods within cylinders. Featuring an exceptional guide effect, it efficiently absorbs radial forces at any time, prevents metal-to-metal contact within the cylinder, and significantly reduces friction.

The KZT is a combination of a piston seal ring and an anti-wear ring. When used together, these components prevent cylinder oil from mixing with foreign particles, protecting the seals from damage and ensuring a long service life. For piston rod seals, when combined with a metal bushing, they prevent damage to the rods thanks to the impurity submerge function of the PTFE material.

Working Conditions:
• Max Speed: 5 m/s
• Material: Filled PTFE

Frequently Asked Questions
What are the primary functions of KZT seals?
KZT seals are used for moving pistons and rods in cylinders to provide a guiding effect, absorb radial force, and prevent metal-to-metal contact, which reduces friction and wear.
What materials are used for KZT sealing components?
These seals are primarily made of Filled PTFE (Polytetrafluoroethylene), which provides excellent chemical resistance and low friction properties.
What is the maximum operating speed for KZT seals?
KZT seals can handle a maximum operating speed of up to 5 meters per second (5m/s).
How should these seals be stored for maximum longevity?
Seals should be stored flat in sealed containers, away from direct sunlight, UV light, and ozone. The temperature should be maintained below +32°C but above +10°C.
What is the shelf life of PTFE seals?
PTFE compounds have an unlimited shelf life when stored under proper conditions, unlike other materials like NBR or FKM which typically last around 7 years.
Do KZT seals help protect other cylinder components?
Yes, by acting as a barrier against foreign particles and providing a submerge function for impurities, they prevent damage to the piston rods and extend the service life of the entire sealing system.
