PRR seals have a remarkably short working length in relation to the shaft diameter, and due to their flexible membrane can accept considerable misalignment in use.Their pressure capabilities depend upon whether they are used on either parallel or stepped shafts and are shown in the technical data. Technical data link.

The PRR range are available in sizes between 5 mm. and 150 mm. shaft diameter and in a wide variety of materials.
They are particularly suitable for applications where axial space is limited and are normally used with stationary seats types TAR, LTAR, LAR or LBR, dependent upon application.

Operating conditions:
Temperature:-40°C to +180°C depending on material choice

Pressure:up to 10 bar

Speed:up to 12 m/s

Construction:
One piece construction for rapid installation.For pressures above 5 bar the use of a retaining sleeve or stepped shaft will avoid the
risk of the bellows moving on the shaft.
