Thanks to the material combination of metal and hard fabric, this guide ring prevents so-called galling on the devices. It also has a high load-bearing capacity and the chamfered profile edges prevent edge pressure in the corner radii of the installation groove.

Freudenberg Sealing Technologies offers high quality and durable guides as rod guide rings. The entire selection of guide rings including product and material data sheets, ordering options, prices and availability as well as dealer contacts can be found in our FST e-catalog.

Guide rings are used to guide the rod and piston of pneumatic and hydraulic cylinders. These rod guide rings prevent direct metallic contact with the cylinder housing.

The guide rings from Freudenberg Sealing Technologies meet the high requirements needed in the industry: For example, they are able to absorb high lateral forces even with a short guide distance and low friction losses at the same time. Different materials are used that are best suited to the respective degree of load. These include PTFE, polyamide and hard fabric.

For example, it is interchangeable with existing SB and SF type installation spaces, has a high radial load capacity and excellent utilization of the guide length thanks to uniform tension distribution. In addition, the optimized stress distribution in the contact zone between the guide ring and the lubricant improves the intake of lubricants. All rod guide rings from Freudenberg Sealing Technologies are of the highest quality, durable and easy to install.

Guide rings are used in earthmoving equipment, industrial trucks. Agricultural machinery and presses. The Merkel SB guide ring, for example, a non-metallic guide element for rods and for standardized installation spaces in accordance with ISO 10766, is suitable for this purpose.

The patented Merkel Guivex SBK guide ring made of hard fabric is perfect for use in mobile and heavy-duty hydraulics and for preventing the piston rod from bending in long-stroke cylinders. It offers significant advantages over conventional guide bands and rings.

We offer rod guide rings with maximum reliability and durability for every type of cylinder and application. They must be able to absorb high lateral forces even with a short guide distance and low friction losses at the same time. Thanks to the highest quality standards, we are the market leader for guide rings.

The task of guides is to guide the rods and pistons of pneumatic and hydraulic cylinders and prevent them from coming into direct metallic contact with the cylinder housing. The guides of Freudenberg Sealing Technologies are able to take up high shearing forces even in case of a short guiding distance and, at the same time, low frictional losses. They are also available as guide rings. Depending on the load, various materials may be used: PTFE, polyamide and laminated fabric. For every type of cylinder and application, Freudenberg Sealing Technologies offers the right guide with maximum reliability and durability from this portfolio:
