FEY Labyrinth Sealing Rings

Protect components in dirty and abrasive environments up to 700oC

AXIAL & RADIAL MOVEMENT CONSIDERATIONS

Axial

The groove width A or B must be widened by twice the axial play if play occurs in the area of the rings.

Damage to the rings and the surrounding components may occur if this is not adhered to.

It is recommended to use the full groove width tolerances, especially in cases involving thermal expansion.

Radial

The external clamping rings, the groove diameter D1 must be decreased by the radial play if radial play occurs in the area of the rings.

For internal clamping rings, the groove diameter D2 must be increased by the radial play if radial play occurs in the area of the rings.

Damage to the rings and the surrounding components may occur if this is not adhered to.
