SURFACE ROUGHNESS

The housing must be free from burrs and scratches

for optimal operation. The table below sets out

the recommendations for surface roughness to be

followed.

Assembly recommendations

Floating seals are hard cast iron or steel precision parts.

•

The seal must not be removed from its original packaging until just before it is fitted, and it must protect the

operational surfaces (A) from any soiling or deterioration.

•

The housings of the seal (B) must be clean and there must be no burrs around the installation.

•

The floating seals must be fitted using mounting tools (D). They are composed of two bearing shells fitted around

a floating seal. In this way, the exertion required for installation is applied directly through the O'Ring (C).

•

The floating seal must then be inserted into the housing, and all parts must be positioned symmetrically.

•

The O'Rings, once put in place, must not be twisted or jammed.

•

Before the final fitting, a thin film of oil must be applied to the two operational parts with a lint-free cloth (e.g.: a

chamois)
