Rotary Seals

Installation spaces for rotary seals typically take the form of a semi-open groove. However, we may also encounter classic closed rectangular grooves, as well as deep and narrower grooves designed for combined elements (so-called omegats).

When designing and manufacturing installation spaces for static seals, it is necessary to follow the recommendations generally applicable to the construction of sealing elements. In particular, it is essential to adhere to the surface roughness of the sealing groove, Ra ≤ 1.6 μm and Rt ≤ 6.3 μm, and before assembly, also ensure that the sealing groove is free of potential contaminants and that there are no sharp edges, burrs, or other surface imperfections at the given location. It is also necessary to observe the recommended size of the lead-in chamfer in the cylinder or on the piston. Otherwise, damage to the sealing lips may occur during assembly.

Thanks to our technological equipment, we can manufacture sealing elements (and more) up to an outer diameter of 505 mm. However, in cooperation with verified international partners, we can also offer seals of significantly larger diameters.

We maintain a large stock of basic materials, from the smallest sizes up to diameters exceeding 500 mm. This enables us to respond flexibly to urgent requests. We typically manufacture seals within a few days, but in case of need (e.g., breakdowns, urgent repairs of hydraulic equipment), we can produce seals virtually on demand.

We manufacture sealing elements starting from a single piece. However, thanks to the automation elements we utilize in production, we can also efficiently produce large series. We use a wide range of machining tools specifically developed for manufacturing seals and machining specific sealing materials. This enables us to produce many non-standard profiles and shapes, or to perform shape and dimensional modifications of standard profiles.
