Многофункциональные уплотнения вала Multi-Seal

Высокопроизводительное Уплотнение Вала

Конструктивные особенности

Universal shaft seal rings

are produced without metal housing and do basically consist of three elements:

fabric-reinforced Elastomer to secure the seal rings against the casing bore.

seal lips made from a homogeneous Elastomermixture with addition of PTFE (minor friction!)

stainless steel garter spring

Universal shaft seal rings
are available in various
types, in split and endless version.

Applications

Universal shaft seal rings
are generally used in the
engine construction, however, mainly with heavy equipment and shipbuilding (e.g. rolling mill, power transmission, propeller shaft, water turbine etc.).

In addition to the above, they are used where shaft seal rings in a metal housing may not be applied.

Shaft Seal Technical Data

Peripheral speed

With optimum operating conditions the universal shaft seal ring T51 can be used for peripheral speeds of max. 25 m/s. As for type T61, the allowed peripheral speed depends on the pressure load (Please see diagram).

Hardness of seal surface

Depending on the operating conditions 40 – 45 HRC.

Quality of seal surface

shaft_seal_technical_data_chart_01 Grinding of the shaft surface must be plunge grinded.

Pressure

The universal shaft seals T51 and T53 are only used in applications without pressure load. With pressure differences, type T52 can be used according to DIN 3769 depending on the rotating speed and peripheral speed (max. 0.5 bar).

Run-out and misalignment

Because of their construction, the universal shaft seals are able to accept high rotation and concentric deviations in the radial direction. The diameter and the peripheral speed are the decisive parameters.
