High-Pressure Rotary Shaft Seals for Pressure-Loaded Rotary Applications
High-pressure rotary shaft seals from INNSEALS are designed for applications where rotating shafts must be reliably sealed against elevated pressures. They are used, among other applications, in hydraulic pumps, hydraulic motors and power steering systems.
Depending on the design type, rotational speed and temperature, high-pressure rotary shaft seals can be used at a continuous pressure of up to 30 bar. Pressure peaks of up to 60 bar are possible with a suitable version.

High-Pressure Rotary Shaft Seals from INNSEALS
High-pressure rotary shaft seals are special rotary seals for applications where increased system pressure must be considered in addition to rotational movement. They are used when standard rotary shaft seals are not sufficiently designed for the existing pressure conditions.
The appropriate design type, pressure load, rotational speed, temperature and medium to be sealed are decisive for reliable performance. INNSEALS supports you in selecting a version that matches the specific operating conditions.
Pressure Load in High-Pressure Rotary Shaft Seals
Various design types of high-pressure rotary shaft seals can be used for high pressure loads depending on rotational speed and temperature. A distinction must be made between continuous operating pressure and short-term pressure peaks.

Your FAQs answered
Frequently asked questions:
High-pressure shaft seals are used when elevated pressures occur in applications that can no longer be safely managed with standard seals. They ensure reliable sealing even under extreme conditions.
Standard shaft seals can fail, deform or become leaky under excessive pressure. This can lead to leakage, increased wear and in the worst case damage to the machine.
They have reinforced sealing lips, more stable housings and often additional support elements. This design makes it possible to safely seal significantly higher pressures.
Important factors are the pressure range, temperature, rotational speed and chemical resistance to the medium. Careful selection increases service life and operational reliability.
No, with correct design and installation they work reliably over long periods. Nevertheless they should be regularly inspected to detect wear or damage early.
