Sealing Rings

Sealing Rings for Hydraulics, Mechanical Engineering and Tail Gates – Reliable Sealing in the System

Sealing rings are universal sealing elements in mechanical engineering and perform a central function in a wide range of technical applications. In this category you will find sealing rings suitable for use in hydraulic systems, mechanical assemblies and especially on tail gates. They ensure that liquids and pressure media are reliably retained within the system while also preventing the ingress of dirt, moisture and foreign particles. Sealing rings therefore make a decisive contribution to the functional reliability, efficiency and service life of technical systems.

Function and Application Areas of Sealing Rings

Sealing rings are used wherever moving or static components must be reliably sealed against each other. In hydraulic systems they prevent hydraulic oil from escaping and thus maintain the necessary operating pressure. At the same time, they protect sensitive components from external influences and reduce wear on sealing surfaces and moving parts. On tail gates, sealing rings perform important functions in hydraulic cylinders, valves and line systems. They ensure that pressure can be built up and maintained and that platform movements run smoothly and in a controlled manner. They fulfil comparable functions in other machines and systems as well and are therefore universally applicable.

Designs, Materials and Technical Versions

Sealing rings are manufactured in different designs and materials to meet the respective requirements. Depending on the area of use, O-rings, shaft sealing rings or special profile seals are used, for example. The selection depends, among other things, on pressure, temperature, medium and mechanical load. Typical materials include NBR (nitrile rubber), FKM (Viton) or other elastomeric materials that offer high resistance to oil, temperature and mechanical stress. PTFE-based seals are also used for special applications and are characterised by particularly low friction and high chemical resistance. A precisely fitting design is crucial: only correctly dimensioned sealing rings ensure reliable sealing and prevent leaks or premature wear.

Wear, Maintenance and Replacement of Sealing Rings

Sealing rings are subject to natural wear during operation. Mechanical movement, pressure load, temperature changes and chemical influences can cause the material to harden, become brittle or lose its sealing effect over time. Typical signs include oil loss, pressure drop or visible damage to the sealing element. As part of maintenance, sealing rings should be checked regularly and replaced when necessary. Especially in hydraulic applications, timely replacement is crucial in order to avoid malfunctions and consequential damage to pumps, cylinders or valves. Replacing sealing rings is one of the classic repair measures and can be carried out quickly and efficiently in many cases.

Quality and Reliability of Sealing Rings

The quality of sealing rings has a direct influence on the operational safety and performance of a system. Inferior materials or inaccurate dimensions can lead to leaks, increased wear and failures. High-quality sealing rings are characterised by precise manufacturing, high material resistance and a permanently reliable sealing effect. At SULEJ Ladebordwand you will find precisely fitting sealing rings that are suitable both for use on tail gates and for general hydraulic applications. They help to seal systems reliably, optimise maintenance intervals and extend the service life of technical components.

Selection and Use of Suitable Sealing Elements

The sealing rings offered in this category are suitable for a wide range of applications and allow quick selection of suitable sealing elements for maintenance, repair and replacement.
