SPEED

Floating seals can withstand speeds of up to 10 m/s depending on the quality of the materials selected for the metal

friction rings.

The graph below sets out the limitations of use according to the materials.

The graph below converts the rotation speed (rpm) into peripheral speed (m/s) according to the outside diameter

ØDa of the seal.

Peripherical speed (m/s)

Possible

grease lubrication

Installation dimension I to be adpated

Example : for a diameter ØDa = 245,00 mm with a speed of 400 r.p.m,

the peripheral speed is 5,13 m/s and installation dimension I is to be adapted.
