Guide Strip: page 4

The guide strip is a high-tech component used in hydraulic cylinders to guide the piston and rod, absorb lateral forces and protect the contact surfaces against wear. Unlike conventional guide rings, the guide band is supplied in rolls or lengths that can be cut to the required size, offering greater flexibility during installation.

It is made from materials with a low coefficient of friction, which are compatible with hydraulic fluids and resistant to a range of temperatures.

In the Hydraulic Seals Shop catalogue, you can find guide strips in stock in Romania, made from PTFE, POM and composite materials — with fast delivery. 

What is a guide strip and why is it important in hydraulic cylinders 

The guide strip serves the same function as guide rings, but has an additional advantage: it can be cut to any length and fitted into mounting grooves of various shapes. It centres the piston or rod within the cylinder, absorbing radial forces and reducing friction to protect both the moving parts and the cylinder’s inner surface. 

Piston and rod guidance 

It is fitted into special grooves in the piston or rod, and the guide band maintains a controlled clearance relative to the cylinder wall. This prevents metal-to-metal contact, reduces vibration and operating noise, and helps ensure smooth cylinder movement. It is particularly advantageous in applications with high lateral loads or in long-stroke cylinders.

Surface protection against wear 

The material of the guide strip, whether PTFE, POM or resin-based composites, has a lower hardness compared to metal. This means that the strip wears out first, protecting the cylinder’s expensive surfaces. The guide strip is easier and more cost-effective to replace than reconditioning a damaged cylinder.

What determines the price of the guide strip?

The cost of guide strips varies depending on the material (standard PTFE, PTFE with strength-enhancing additives, POM or special composites), width, thickness and length. Strips made from special materials or with tight tolerances are more expensive, but offer superior performance in demanding applications. See also the guide rings, Vee Packing seals and static seals categories for standardised guiding solutions.

Frequently Asked Questions 

What is a guide strip? 

A guide strip is a technical component in hydraulic cylinders used to guide the piston and rod, absorbing lateral forces and protecting the contact surfaces from wear. It is supplied in rolls and cut to the required size.

What is the purpose of a guide band in hydraulic systems?

It centres the piston or rod within the cylinder, absorbs radial forces and reduces friction — all of which help to protect the cylinder’s internal surfaces and extend the service life of the assembly.

What materials is the guide strip made from? 

The guide band can be made from PTFE (with or without additives), POM or resin-based composite materials. The choice of material depends on the load parameters, the operating temperature and the type of hydraulic fluid.

Can I buy the guide band online? 

Yes, you can order the guide band from the Hydraulic Seals Online catalogue in the required quantity for fast delivery to your address in Romania.
